* Patch by Thomas Frieden, 13 Nov 2002:
Add code for AmigaOne board
(preliminary merge to U-Boot, still WIP)
* Patch by Jon Diekema, 12 Nov 2002:
- Adding URL for IEEE OUI lookup
- Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
being defined.
- In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
root-on-nfs macros are designed to switch how the default boot
method gets defined.

+/**********************************************************************
+ * How it works:
+ * -------------
+ * The framelist / Transfer descriptor / Queue Heads are similar like
+ * in the linux usb_uhci.c.
+ *
+ * During initialization, the following skeleton is allocated in init_skel:
+ *
+ * framespecific | common chain
+ *
+ * framelist[]
+ * [ 0 ]-----> TD ---------\
+ * [ 1 ]-----> TD ----------> TD ------> QH -------> QH -------> QH ---> NULL
+ * ... TD ---------/
+ * [1023]-----> TD --------/
+ *
+ * ^^ ^^ ^^ ^^ ^^
+ * 7 TDs for 1 TD for Start of Start of End Chain
+ * INT (2-128ms) 1ms-INT CTRL Chain BULK Chain
+ *
+ *
+ * Since this is a bootloader, the isochronous transfer descriptor have been removed.
+ *
+ * Interrupt Transfers.
+ * --------------------
+ * For Interupt transfers USB_MAX_TEMP_INT_TD Transfer descriptor are available. They
+ * will be inserted after the appropriate (depending the interval setting) skeleton TD.
+ * If an interrupt has been detected the dev->irqhandler is called. The status and number
+ * of transfered bytes is stored in dev->irq_status resp. dev->irq_act_len. If the
+ * dev->irqhandler returns 0, the interrupt TD is removed and disabled. If an 1 is returned,
+ * the interrupt TD will be reactivated.
+ *
+ * Control Transfers
+ * -----------------
+ * Control Transfers are issued by filling the tmp_td with the appropriate data and connect
+ * them to the qh_cntrl queue header. Before other control/bulk transfers can be issued,
+ * the programm has to wait for completion. This does not allows asynchronous data transfer.
+ *
+ * Bulk Transfers
+ * --------------
+ * Bulk Transfers are issued by filling the tmp_td with the appropriate data and connect
+ * them to the qh_bulk queue header. Before other control/bulk transfers can be issued,
+ * the programm has to wait for completion. This does not allows asynchronous data transfer.

+REMARKS:
+This enumeration defines the type values passed to the PM_agpReservePhysical
+function, to define how the physical memory mapping should be handled.
+
+The PM_agpUncached type indicates that the memory should be allocated as
+uncached memory.
+
+The PM_agpWriteCombine type indicates that write combining should be enabled
+for physical memory mapping. This is used for framebuffer write combing and
+speeds up direct framebuffer writes to the memory.
+
+The PM_agpIntelDCACHE type indicates that memory should come from the Intel
+i81x Display Cache (or DCACHE) memory pool. This flag is specific to the
+Intel i810 and i815 controllers, and should not be passed for any other
+controller type.

+;* Language: NetWide Assembler (NASM) or Turbo Assembler (TASM)
+;* Environment: Any Intel Environment
+;*
+;* Description: Macros to provide memory model independant assembly language
+;* module for C programming. Supports the large and flat memory
+;* models.
+;*
+;* The defines that you should use when assembling modules that
+;* use this macro package are:
+;*
+;* __LARGE__ Assemble for 16-bit large model
+;* __FLAT__ Assemble for 32-bit FLAT memory model
+;* __NOU__ No underscore for all external C labels
+;* __NOU_VAR__ No underscore for global variables only
+;*
+;* The default settings are for 16-bit large memory model with
+;* leading underscores for symbol names.
+;*
+;* The main intent of the macro file is to enable programmers
+;* to write _one_ set of source that can be assembled to run
+;* in either 16 bit real and protected modes or 32 bit
+;* protected mode without the need to riddle the code with
+;* 'if flatmodel' style conditional assembly (it is still there
+;* but nicely hidden by a macro layer that enhances the
+;* readability and understandability of the resulting code).
+;*
+;****************************************************************************
+
+; Include the appropriate version in here depending on the assembler. NASM
+; appears to always try and parse code, even if it is in a non-compiling
+; block of a ifdef expression, and hence crashes if we include the TASM
+; macro package in the same header file. Hence we split the macros up into
+; two separate header files.

+Data structure containing ponters to programmed I/O functions used by the

+I/O for the emulator to handled as necessary by the user program. By
+default the emulator contains simple functions that do not do access the
+hardware in any way. To allow the emualtor access the hardware, you will
+need to override the programmed I/O functions using the X86EMU_setupPioFuncs
+function.

+DESCRIPTION:
+Parse the command line for specific options
+
+HEADER:
+cmdline.h
+
+PARAMETERS:
+argc - Value passed to program through argc variable
+argv - Pointer to the argv array passed to the program
+format - A string representing the expected format of the command line
+argument - Pointer to optional argument on command line
+
+RETURNS:
+Character code representing the next option parsed from the command line by
+getcmdopt. Returns ALLDONE (-1) when there are no more parameters to be parsed
+on the command line, PARAMETER (-2) when the argument being parsed is a
+parameter and not an option switch and lastly INVALID (-3) if an error
+occured while parsing the command line.
+
+REMARKS:
+Function to parse the command line option switches in UNIX System V style.
+When getcmdopt is called, it returns the character code of the next valid
+option that is parsed from the command line as specified by the Format
+string. The format string should be in the following form:
+
+ "abcd:e:f:"
+
+where a,b and c represent single switch style options and the character
+code returned by getcmdopt is the only value returned. Also d, e and f
+represent options that expect arguments immediately after them on the
+command line. The argument that follows the option on the command line is
+returned via a reference in the pointer argument. Thus a valid command line
+for this format string might be:
+
+ myprogram -adlines -b -f format infile outfile
+
+where a and b will be returned as single character options with no argument,
+while d is returned with the argument lines and f is returned with the
+argument format.
+
+When getcmdopt returns with PARAMETER (we attempted to parse a paramter, not
+an option), the global variable NextArgv will hold an index in the argv
+array to the argument on the command line AFTER the options, ie in the

+* Description: Generic Memory Type Range Register (MTRR) functions to
+* manipulate the MTRR registers on supported CPU's. This code
+* *must* run at ring 0, so you can't normally include this
+* code directly in normal applications (the except is DOS4GW
+* apps which run at ring 0 under real DOS). Thus this code
+* will normally be compiled into a ring 0 device driver for
+* the target operating system.

+;*
+;* Language: NASM or TASM Assembler
+;* Environment: IBM PC (MS DOS)
+;*
+;* Description: Uses the 8253 timer and the BIOS time-of-day count to time
+;* the performance of code that takes less than an hour to
+;* execute.
+;*
+;* The routines in this package only works with interrupts
+;* enabled, and in fact will explicitly turn interrupts on
+;* in order to ensure we get accurate results from the timer.
+;*
+;* Externally 'C' callable routines:
+;*
+;* LZ_timerOn: Saves the BIOS time of day count and starts the
+;* long period Zen Timer.
+;*
+;* LZ_timerLap: Latches the current count, and keeps the timer running
+;*
+;* LZ_timerOff: Stops the long-period Zen Timer and saves the timer
+;* count and the BIOS time of day count.
+;*
+;* LZ_timerCount: Returns an unsigned long representing the timed count
+;* in microseconds. If more than an hour passed during
+;* the timing interval, LZ_timerCount will return the
+;* value 0xFFFFFFFF (an invalid count).
+;*
+;* Note: If either more than an hour passes between calls to LZ_timerOn
+;* and LZ_timerOff, an error is reported. For timing code that takes
+;* more than a few minutes to execute, use the low resolution
+;* Ultra Long Period Zen Timer code, which should be accurate
+;* enough for most purposes.
+;*
+;* Note: Each block of code being timed should ideally be run several
+;* times, with at least two similar readings required to
+;* establish a true measurement, in order to eliminate any
+;* variability caused by interrupts.
+;*
+;* Note: Interrupts must not be disabled for more than 54 ms at a
+;* stretch during the timing interval. Because interrupts are
+;* enabled, key, mice, and other devices that generate interrupts
+;* should not be used during the timing interval.
+;*
+;* Note: Any extra code running off the timer interrupt (such as
+;* some memory resident utilities) will increase the time
+;* measured by the Zen Timer.
+;*
+;* Note: These routines can introduce inaccuracies of up to a few
+;* tenths of a second into the system clock count for each
+;* code section being timed. Consequently, it's a good idea to
+;* reboot at the conclusion of timing sessions. (The
+;* battery-backed clock, if any, is not affected by the Zen
+;* timer.)
+;*
+;* All registers and all flags are preserved by all routines, except
+;* interrupts which are always turned on

+REMARKS:
+This function allows the application programmer to install an event filter

+new event that will be placed into the event queue. Your callback can the
+modify the contents of the event before it is placed into the queue (for
+instance adding custom information or perhaps high precision timing
+information).
+
+If your callback returns FALSE, the event will be ignore and will not be
+posted to the event queue. You should always return true from your event
+callback unless you plan to use the events immediately that they are
+recieved.
+
+Note: Your event callback may be called in response to a hardware
+ interrupt and will be executing in the context of the hardware
+ interrupt handler under MSDOS (ie: keyboard interrupt or mouse
+ interrupt). For this reason the code pages for the callback that
+ you register must be locked in memory with the PM_lockCodePages
+ function. You must also lock down any data pages that your function
+ needs to reference as well.
+
+Note: You can also use this filter callback to process events at the
+ time they are activated by the user (ie: when the user hits the
+ key or moves the mouse), but make sure your code runs as fast as
+ possible as it will be executing inside the context of an interrupt
+ handler on some systems.

+queue for later retrieval.
+
+Note: Most analogue joysticks will provide readings that change even
+ though the joystick has not moved. Hence if you call this routine
+ you will likely get an EVT_JOYMOVE event every time through your
+ event loop.

+Hence we simply open the file handle every time that we need to call the
+device driver to work around these problems.

+it with a handler that does an MGL_exit() before terminating the application

+
+REMARKS:
+Starts the Long Period Zen Timer counting. Once you have started the timer,
+you can stop it with LZTimerOff or you can latch the current count with
+LZTimerLap.
+
+The Long Period Zen Timer uses a number of different high precision timing
+mechanisms to obtain microsecond accurate timings results whenever possible.
+The following different techniques are used depending on the operating
+system, runtime environment and CPU on the target machine. If the target
+system has a Pentium CPU installed which supports the Read Time Stamp
+Counter instruction (RDTSC), the Zen Timer library will use this to
+obtain the maximum timing precision available.
+
+Under 32-bit Windows, if the Pentium RDTSC instruction is not available, we
+first try to use the Win32 QueryPerformanceCounter API, and if that is not
+available we fall back on the timeGetTime API which is always supported.
+
+Under 32-bit DOS, if the Pentium RDTSC instruction is not available, we
+then do all timing using the old style 8253 timer chip. The 8253 timer
+routines provide highly accurate timings results in pure DOS mode, however
+in a DOS box under Windows or other Operating Systems the virtualization
+of the timer can produce inaccurate results.
+
+Note: Because the Long Period Zen Timer stores the results in a 32-bit
+ unsigned integer, you can only time periods of up to 2^32 microseconds,
+ or about 1hr 20mins. For timing longer periods use the Ultra Long
+ Period Zen Timer.

+REMARKS:
+Starts the Ultra Long Period Zen Timer counting. Once you have started the
+timer, you can stop it with ULZTimerOff or you can latch the current count

+
+The Ultra Long Period Zen Timer uses the available operating system services
+to obtain accurate timings results with as much precision as the operating
+system provides, but with enough granularity to time longer periods of
+time than the Long Period Zen Timer. Note that the resolution of the timer
+ticks is not constant between different platforms, and you should use the
+ULZTimerResolution function to determine the number of seconds in a single
+tick of the timer, and use this to convert the timer counts to seconds.
+
+Under 32-bit Windows, we use the timeGetTime function which provides a
+resolution of 1 millisecond (0.001 of a second). Given that the timer
+count is returned as an unsigned 32-bit integer, this we can time intervals
+that are a maximum of 2^32 milliseconds in length (or about 1,200 hours or
+50 days!).
+
+Under 32-bit DOS, we use the system timer tick which runs at 18.2 times per
+second. Given that the timer count is returned as an unsigned 32-bit integer,
+this we can time intervals that are a maximum of 2^32 * (1/18.2) in length
+(or about 65,550 hours or 2731 days!).

+
+This is a preliminary version of a VGA softbooter for LINUX.
+
+It makes use of the of the vm86() call and is therefore only
+usable on ix86 systems.
+There are plans to port this program to use a x86 emulator
+like x86emu. Also it may be ported to other operating systems.
+
+So far it has been tested on a small number of cards. It might
+well be that it will fail on your card.
+
+If you need to make modifications to the programs to be able
+to boot your card please let the author know.
+
+So far there is no command line interface. All options need
+to be hardcoded. You can do this by editing debug.h. You can
+turn on a bunch of debug output. Other options allow you to
+boot the primary card (CONFIG_ACTIVE_DEVICE), save the bios
+to a file (SAVE_BIOS), and map the original system bios
+(MAP_SYS_BIOS).
+
+The author wants to thank
+ Hans Lermen (dosemu)
+ and
+ Kendall Bennett (x86emu)
+for their support.
+
+Parts of the code - especially in v86.c and io.c - are based on code
+taken from dosemu. Parts of the code in int.c are based on code taken
+from x86emu

+What I had to do to make cards happy:
+
+1. Tseng ET4000 W32P
+This card wants to call the original system BIOS video routines.
+It sets the int 0x42 vector to F000:F065, the entry point to the
+system bios video routines.
+CAVE: don't catch int 0x42 and use the vbios int 0x10 routines.
+At early stage during initialization they call int 0x42. This
+causes an infinite loop.
+
+2. ATi Mach64 Rage IIc AGP
+This card does similar things like the Tseng ET4000 W32P.
+However it doesn't have the problem with the ininite loop.
+
+3. Elsa Victory II-A16 AGP Banshee
+This card is very clever: It knows it is an AGP card. Therefore
+it knows it is behind a PCI-PCI bridge. It also knows that noone
+else is behind this bridge. Therefore it start reprogramming the
+bridge! For this it assumes the AGP bridge is on bus 1.
+
+4. Elsa Gloria Synergy 8 ViVo AGP PM2
+This card likes to see a complete interrupt vector table. If
+we fill this table with 0 the VBIOS detects this and quits
+initialization.
+
+5. Dimond Viper 330 AGP NVIDIA Riva 128.
+This card has a similar problem like the Elsa Gloria. It wants
+to read the system BIOS date at 0xffffd.
+
+6. Matrox Mystique PCI
+This card reads the IO port 0x62. If it doesn't like what it sees
+it loops forever. To keep the card happy put 0xfc into 0xffffe.
+This location holds the system model id. 0xfc means IBM-AT.
+ One can make an interesting observation: this card likes to know
+with whom it has to share the system. Therefore it accesses PCI
+config space of all the other cards. It does this bypassing the
+PCI BIOS by reading the PCI access ports directly.
+
+7. Matrox G100 AGP
+This card has the same problem as the Mystique.
+
+Apperantly this works now. However not all combinations of cards are
+checked, yet.
+
+Further notes:
+the IO register 0x42-0x43 as well as 0x61-0x63 are of special interest
+for many graphic cards. They should be emulated.
+The so called "Industry Standard BIOS Entry Points" to int 0x42 (0xFF065)
+and to int 0x1a (0xFFE6E) should be filled with useful code. This code
+needs to return as if it was called as int.
+The subvendor ID PCI registers might cause problems. On some chipsets
+they are programmed in a non-obivous non-PCI conformant way.
+V_Bioses are seen to modify the following int:
+0x10 (default video), 0x1f(font table), 0x42(copy of default video),
+0x43 (??), 0x6d (copy of default video - same as 0x10?)
+
+TODO:
+Int 0x6d needs to be done.
+All interrupts where there is no default industry standard entry point
+should point to an unused location in the 0xF000 segmant (possibly
+0xF0000). This way they could be trapped. A trap handler for
+a. int 0x42 and int 0x1a needs to be implemented.
+The default "industry entry point" for video and PCI (0xFFE6E) should
+also be implemented. (any others?) They should either be routed to
+int 0x42(0x6d?) (video) and 0x1A (PCI) or some other interrupts to
+trap them. Mapping of system bios might not be a good idea. Maybe
+the system bios area should just be filled with "hlt" to trap any
+access there.
+Handling of timer IO registers 0x42, 0x43 and IO registers 0x61, 0x62.
+
+Find documentation:
+- on interrupt vector table
+- on industry standard entry points to the system bios
+- on IO registers 0x61 and 0x62

+ ds segment override
+ es segment override

+ ss segment override

+*
+* ========================================================================
+*
+* Language: ANSI C
+* Environment: Any
+* Developer: Kendall Bennett
+*
+* Description: This file includes subroutines to implement the decoding
+* and emulation of all the x86 processor instructions.
+*
+* There are approximately 250 subroutines in here, which correspond
+* to the 256 byte-"opcodes" found on the 8086. The table which
+* dispatches this is found in the files optab.[ch].
+*
+* Each opcode proc has a comment preceeding it which gives it's table
+* address. Several opcodes are missing (undefined) in the table.
+*
+* Each proc includes information for decoding (DECODE_PRINTF and
+* DECODE_PRINTF2), debugging (TRACE_REGS, SINGLE_STEP), and misc
+* functions (START_OF_INSTR, END_OF_INSTR).
+*
+* Many of the procedures are *VERY* similar in coding. This has
+* allowed for a very large amount of code to be generated in a fairly
+* short amount of time (i.e. cut, paste, and modify). The result is
+* that much of the code below could have been folded into subroutines
+* for a large reduction in size of this file. The downside would be
+* that there would be a penalty in execution speed. The file could
+* also have been *MUCH* larger by inlining certain functions which
+* were called. This could have resulted even faster execution. The
+* prime directive I used to decide whether to inline the code or to
+* modularize it, was basically: 1) no unnecessary subroutine calls,
+* 2) no routines more than about 200 lines in size, and 3) modularize
+* any code that I might not get right the first time. The fetch_*
+* subroutines fall into the latter category. The The decode_* fall
+* into the second category. The coding of the "switch(mod){ .... }"
+* in many of the subroutines below falls into the first category.
+* Especially, the coding of {add,and,or,sub,...}_{byte,word}
+* subroutines are an especially glaring case of the third guideline.
+* Since so much of the code is cloned from other modules (compare
+* opcode #00 to opcode #01), making the basic operations subroutine
+* calls is especially important; otherwise mistakes in coding an
+* "add" would represent a nightmare in maintenance.

+*
+* Description: This file contains the code to implement the primitive
+* machine operations used by the emulation code in ops.c
+*
+* Carry Chain Calculation
+*
+* This represents a somewhat expensive calculation which is
+* apparently required to emulate the setting of the OF and AF flag.
+* The latter is not so important, but the former is. The overflow
+* flag is the XOR of the top two bits of the carry chain for an
+* addition (similar for subtraction). Since we do not want to
+* simulate the addition in a bitwise manner, we try to calculate the
+* carry chain given the two operands and the result.
+*
+* So, given the following table, which represents the addition of two
+* bits, we can derive a formula for the carry chain.
+*
+* a b cin r cout
+* 0 0 0 0 0
+* 0 0 1 1 0
+* 0 1 0 1 0
+* 0 1 1 0 1
+* 1 0 0 1 0
+* 1 0 1 0 1
+* 1 1 0 0 1
+* 1 1 1 1 1
+*
+* Construction of table for cout:
+*
+* ab
+* r \ 00 01 11 10
+* |------------------
+* 0 | 0 1 1 1
+* 1 | 0 0 1 0
+*
+* By inspection, one gets: cc = ab + r'(a + b)
+*
+* That represents alot of operations, but NO CHOICE....
+*
+* Borrow Chain Calculation.
+*
+* The following table represents the subtraction of two bits, from
+* which we can derive a formula for the borrow chain.
+*
+* a b bin r bout
+* 0 0 0 0 0
+* 0 0 1 1 1
+* 0 1 0 1 1
+* 0 1 1 0 1
+* 1 0 0 1 0
+* 1 0 1 0 0
+* 1 1 0 0 0
+* 1 1 1 1 1
+*
+* Construction of table for cout:
+*
+* ab
+* r \ 00 01 11 10
+* |------------------
+* 0 | 0 1 0 0
+* 1 | 1 1 1 0
+*
+* By inspection, one gets: bc = a'b + r(a' + b)

+* Description: Program to validate the x86 emulator library for
+* correctness. We run the emulator primitive operations
+* functions against the real x86 CPU, and compare the result
+* and flags to ensure correctness.
+*
+* We use inline assembler to compile and build this program.
