Changes since U-Boot 1.1.4:
======================================================================
+* Add command for handling DDR ECC registers on MPC8349EE MDS board.
+
+* Fix DDR ECC bit definitions for MPC83xx.
+
+* Add initial support for MPC8349E MDS board.
+
+* Add support for ECC DDR initialization on MPC83xx.
+
+* Add DMA support for MPC83xx.
+
+* Add sync in do_reset() routine for MPC83xx after RPR register
+ was written to. It is need on some targets when BAT translation
+ is enabled.
+
+* Add bit definitions for MPC83xx DDR controller registers.
+
+* Add Dcbz(), Dcbi() and Dcbf() routines for MPC83xx.
+
+* Correct shift offsets in icache_status and dcache_status for MPC83xx.
+
+* Add support for DS1374 RTC chip.
+
+* Add support for Lite5200B board.
+ Patch by Patch by Jose Maria (Txema) Lopez, 16 Jan 2006
+
+* Apply SoC concept to arm926ejs CPUs, i.e. move the SoC specific
+ timer and cpu_reset code from cpu/$(CPU) into the new
+ cpu/$(CPU)/$(SOC) directories
+ Patch by Andreas Engel, 13 Mar 2006
+
+* Change max size of uncompressed uImage's to 8MByte and add
+ CFG_BOOTM_LEN to adjust this setting.
+
+ As mentioned by Robin Getz on 2005-05-24 the size of uncompressed
+ uImages was restricted to 4MBytes. This default size is now
+ increased to 8Mbytes and can be overrided by setting CFG_BOOTM_LEN
+ in the board config file.

+ incorrectly generating start/stop conditions on the bus.
+ Patch by Andrew Dyer, 26 Jul 2005
+
+* Fix bug in [id]cache_status commands for MPC85xx processors;
+ should look at LSB of L1CSRn registers to determine if L1 cache is
+ enabled, not the MSB.

+ (broken!) versions of GCC generate byte accesses when encountering
+ the packed attribute regardless if the struct is already correctly
+ aligned for a platform. Peripherals that can only handle word

+ there is no need to packed the struct in that case.

+Overview
+========
+
+The overall usage pattern for ECC diagnostic commands is the following:
+
+ * (injecting errors is initially disabled)
+
+ * define inject mask (which tells the DDR controller what type of errors
+ we'll be injecting: single/multiple bit etc.)
+
+ * enable injecting errors - from now on the controller injects errors as
+ indicated in the inject mask
+
+IMPORTANT NOTICE: enabling injecting multiple-bit errors is potentially
+dangerous as such errors are NOT corrected by the controller. Therefore caution
+should be taken when enabling the injection of multiple-bit errors: it is only
+safe when used on a carefully selected memory area and used under control of
+the 'ecc test' command (see example 'Injecting Multiple-Bit Errors' below). In
+particular, when you simply set the multiple-bit errors in inject mask and
+enable injection, U-Boot is very likely to hang quickly as the errors will be
+injected when it accesses its code, data etc.
+
+
+Use cases for DDR 'ecc' command:
+================================
+
+Before executing particular tests reset target board or clear status registers:
+
+=> ecc captureclear
+=> ecc errdetectclr all
+=> ecc sbecnt 0
+
+
+Injecting Single-Bit Errors
+---------------------------
+
+1. Set 1 bit in Data Path Error Inject Mask
+
+=> ecc injectdatahi 1
+
+2. Run test over some memory region
+
+=> ecc test 200000 10
+
+3. Check ECC status
+
+=> ecc status
+...
+Memory Data Path Error Injection Mask High/Low: 00000001 00000000
+...
+Memory Single-Bit Error Management (0..255):
+ Single-Bit Error Threshold: 255
+ Single Bit Error Counter: 16
+...
+Memory Error Detect:
+ Multiple Memory Errors: 0
+ Multiple-Bit Error: 0
+ Single-Bit Error: 0
+...
+
+16 errors were generated, Single-Bit Error flag was not set as Single Bit Error
+Counter did not reach Single-Bit Error Threshold.
+
+4. Make sure used memory region got re-initialized with 0xcafecafe pattern
+
+=> md 200000
+00200000: cafecafe cafecafe cafecafe cafecafe ................
+00200010: cafecafe cafecafe cafecafe cafecafe ................

+00200080: deadbeef deadbeef deadbeef deadbeef ................
+00200090: deadbeef deadbeef deadbeef deadbeef ................
+
+
+Injecting Multiple-Bit Errors
+-----------------------------
+
+1. Set more than 1 bit in Data Path Error Inject Mask
+
+=> ecc injectdatahi 5
+
+2. Run test over some memory region
+
+=> ecc test 200000 10
+
+3. Check ECC status
+
+=> ecc status
+...
+Memory Data Path Error Injection Mask High/Low: 00000005 00000000
+...
+Memory Error Detect:
+ Multiple Memory Errors: 1
+ Multiple-Bit Error: 1
+ Single-Bit Error: 0
+...
+
+Observe that both Multiple Memory Errors and Multiple-Bit Error flags are set.
+
+4. Make sure used memory region got re-initialized with 0xcafecafe pattern
+
+=> md 200000
+00200000: cafecafe cafecafe cafecafe cafecafe ................
+00200010: cafecafe cafecafe cafecafe cafecafe ................
+00200020: cafecafe cafecafe cafecafe cafecafe ................
+00200030: cafecafe cafecafe cafecafe cafecafe ................
+00200040: cafecafe cafecafe cafecafe cafecafe ................
+00200050: cafecafe cafecafe cafecafe cafecafe ................
+00200060: cafecafe cafecafe cafecafe cafecafe ................
+00200070: cafecafe cafecafe cafecafe cafecafe ................
+00200080: deadbeef deadbeef deadbeef deadbeef ................
+00200090: deadbeef deadbeef deadbeef deadbeef ................
+
+
+Test Single-Bit Error Counter and Threshold
+-------------------------------------------
+
+1. Set 1 bit in Data Path Error Inject Mask
+
+=> ecc injectdatahi 1
+
+2. Enable error injection
+
+=> ecc inject en
+
+3. Let u-boot run for a with Single-Bit error injection enabled
+
+4. Disable error injection
+
+=> ecc inject dis
+
+4. Check status
+
+=> ecc status
+
+...
+Memory Single-Bit Error Management (0..255):
+ Single-Bit Error Threshold: 255
+ Single Bit Error Counter: 60
+
+Memory Error Detect:
+ Multiple Memory Errors: 1
+ Multiple-Bit Error: 0
+ Single-Bit Error: 1
+...
+
+Observe that Single-Bit Error is 'on' which means that Single-Bit Error Counter
+reached Single-Bit Error Threshold. Multiple Memory Errors bit is also 'on', that
+is Counter reached Threshold more than one time (it wraps back after reaching
+Threshold).

+
+
+NOTE:
+=====
+
+We now use a complete rewrite of the NAND code based on what is in
+2.6.12 Linux kernel.
+
+The old NAND handling code has been re-factored and is now confined
+to only board-specific files and - unfortunately - to the DoC code
+(see below). A new configuration variable has been introduced:
+CFG_NAND_LEGACY, which has to be defined in the board config file if
+that board uses legacy code. If CFG_NAND_LEGACY is defined, the board
+specific config.mk file should also have "BOARDLIBS =
+drivers/nand_legacy/libnand_legacy.a". For boards using the new NAND
+approach (PPChameleon and netstar at the moment) no variable is
+necessary, but the config.mk should have "BOARDLIBS =
+drivers/nand/libnand.a".
+
+The necessary changes have been made to all affected boards, and no
+build breakage has been introduced, except for NETTA and NETTA_ISDN
+targets from MAKEALL. This is due to the fact that these two boards
+use JFFS, which has been adopted to use the new NAND, and at the same
+time use NAND in legacy mode. The breakage will disappear when the
+board-specific code is changed to the new NAND.
+
+As mentioned above, the legacy code is still used by the DoC subsystem.
+The consequence of this is that the legacy NAND can't be removed from
+the tree until the DoC is ported to use the new NAND support (or boards
+with DoC will break).

+ * drivers/mtd/nand.c
+ *
+ * Overview:
+ * This is the generic MTD driver for NAND flash devices. It should be
+ * capable of working with almost all NAND chips currently available.
+ * Basic support for AG-AND chips is provided.
+ *
+ * Additional technical information is available on
+ * http://www.linux-mtd.infradead.org/tech/nand.html
+ *
+ * Copyright (C) 2000 Steven J. Hill (sjhill@realitydiluted.com)
+ * 2002 Thomas Gleixner (tglx@linutronix.de)
+ *
+ * 02-08-2004 tglx: support for strange chips, which cannot auto increment
+ * pages on read / read_oob
+ *
+ * 03-17-2004 tglx: Check ready before auto increment check. Simon Bayes
+ * pointed this out, as he marked an auto increment capable chip
+ * as NOAUTOINCR in the board driver.
+ * Make reads over block boundaries work too
+ *
+ * 04-14-2004 tglx: first working version for 2k page size chips
+ *
+ * 05-19-2004 tglx: Basic support for Renesas AG-AND chips
+ *
+ * 09-24-2004 tglx: add support for hardware controllers (e.g. ECC) shared
+ * among multiple independend devices. Suggestions and initial patch
+ * from Ben Dooks <ben-mtd@fluff.org>
+ *
+ * Credits:
+ * David Woodhouse for adding multichip support
+ *
+ * Aleph One Ltd. and Toby Churchill Ltd. for supporting the
+ * rework for 2K page size chips
+ *
+ * TODO:
+ * Enable cached programming for 2k page size chips
+ * Check, if mtd->ecctype should be set to MTD_ECC_HW
+ * if we have HW ecc support.
+ * The AG-AND chips have nice features for speed improvement,
+ * which are not supported yet. Read / program 4 pages in one go.

+ * Description:
+ *
+ * When nand_scan_bbt is called, then it tries to find the bad block table
+ * depending on the options in the bbt descriptor(s). If a bbt is found
+ * then the contents are read and the memory based bbt is created. If a
+ * mirrored bbt is selected then the mirror is searched too and the
+ * versions are compared. If the mirror has a greater version number
+ * than the mirror bbt is used to build the memory based bbt.
+ * If the tables are not versioned, then we "or" the bad block information.
+ * If one of the bbt's is out of date or does not exist it is (re)created.
+ * If no bbt exists at all then the device is scanned for factory marked
+ * good / bad blocks and the bad block tables are created.

+ * For manufacturer created bbts like the one found on M-SYS DOC devices
+ * the bbt is searched and read but never created
+ *
+ * The autogenerated bad block table is located in the last good blocks
+ * of the device. The table is mirrored, so it can be updated eventually.
+ * The table is marked in the oob area with an ident pattern and a version
+ * number which indicates which of both tables is more up to date.
+ *
+ * The table uses 2 bits per block
+ * 11b: block is good
+ * 00b: block is factory marked bad
+ * 01b, 10b: block is marked bad due to wear
+ *
+ * The memory bad block table uses the following scheme:
+ * 00b: block is good
+ * 01b: block is marked bad due to wear
+ * 10b: block is reserved (to protect the bbt area)
+ * 11b: block is factory marked bad
+ *
+ * Multichip devices like DOC store the bad block info per floor.
+ *
+ * Following assumptions are made:
+ * - bbts start at a page boundary, if autolocated on a block boundary
+ * - the space neccecary for a bbt in FLASH does not exceed a block boundary

+ * 02-26-2002 TG added chip_delay to nand_chip structure to optimize
