- AMCC Ebony Board
-
- Last Update: September 12, 2002
-=======================================================================
-
-This file contains some handy info regarding U-Boot and the AMCC
-Ebony evaluation board. See the README.ppc440 for additional
-information.
-
-
-SWITCH SETTINGS & JUMPERS
-==========================
-
-Here's what I've been using successfully. If you feel inclined to
-change things ... please read the docs!
-
-DIPSW U46 U80
-------------------------
-SW 1 off on
-SW 2 on on
-SW 3 on on
-SW 4 off on
-SW 5 on off
-SW 6 on on
-SW 7 on off
-SW 8 on off
-
-J41: strapped
-J42: open
-
-All others are factory default.
-
-
-I2C probe
-=====================
-
-The i2c utilities have been tested on both Rev B. and Rev C. and
-look good. The CONFIG_SYS_I2C_NOPROBES macro is defined to prevent
-probing the CDCV850 clock controller at address 0x69 (since reading
-it causes the i2c implementation to misbehave. The output of
-'i2c probe' should look like this (assuming you are only using a single
-SO-DIMM:
-
-=> i2c probe
-Valid chip addresses: 50 53 54
-Excluded chip addresses: 69
-
-
-GETTING OUT OF I2C TROUBLE
-===========================
-
-If you're like me ... you may have screwed up your bootstrap serial
-eeprom ... or worse, your SPD eeprom when experimenting with the
-i2c commands. If so, here are some ideas on how to get out of
-trouble:
-
-Serial bootstrap eeprom corruption:
------------------------------------
-Power down the board and set the following straps:
-
-J41 - open
-J42 - strapped
-
-This will select the default sys0 and sys1 settings (the serial
-eeproms are not used). Then power up the board and fix the serial
-eeprom using the 'i2c mm' command. Here are the values I currently
-use:
-
-=> i2c md 50 0 10
-0000: bf a2 04 01 ae 94 11 00 00 00 00 00 00 00 00 00 ................
-
-=> i2c md 54 0 10
-0000: 8f b3 24 01 4d 14 11 00 00 00 00 00 00 00 00 00 ..$.M...........
-
-Once you have the eeproms set correctly change the
-J41/J42 straps as you desire.
-
-SPD eeprom corruption:
-------------------------
-I've corrupted the SPD eeprom several times ... perhaps too much coffee
-and not enough presence of mind ;-). By default, the ebony code uses
-the SPD to initialize the DDR SDRAM control registers. So if the SPD
-eeprom is corrupted, U-Boot will never get into ram. Here's how I got
-out of this situation:
-
-0. First, _before_ playing with the i2c utilities, do an 'i2c probe', then
-use 'i2c md' to capture the various device contents to a file. Some day
-you may be glad you did this ... trust me :-). Otherwise try the
-following:
-
-1. In the include/configs/EBONY.h file find the line that defines
-the CONFIG_SPD_EEPROM macro and undefine it. E.g:
-
-#undef CONFIG_SPD_EEPROM
-
-This will make the code use default SDRAM control register
-settings without using the SPD eeprom.
-
-2. Rebuild U-Boot
-
-3. Load the new U-Boot image and reboot ebony.
-
-4. Repair the SPD eeprom using the 'i2c mm' command. Here's the eeprom
-contents that work with the default SO-DIMM that comes with the
-ebony board (micron 8VDDT164AG-265A1). Note: these are probably
-_not_ the factory settings ... but they work.
-
-=> i2c md 53 0 10 80

-PCI DOUBLE-ENUMERATION WOES
-===========================
-
-If you're not using PCI-X cards and are simply using 32-bit and/or
-33 MHz cards via extenders and the like, you may notice that the
-initial pci scan reports various devices twice ... and configuration
-does not succeed (one or more devices are enumerated twice). To correct
-this we replaced the 2K ohm resistor on the IDSEL line(s) with a
-22 ohm resistor and the problem went away. This change hasn't broken
-anything yet -- use at your own risk.
-
-We never tested anything other than 33 MHz/32-bit cards. If you have
-the chance to do this, please let me know how things turn out :-)
-
-
-Regards,
---Scott

- AMCC Ocotea Board
-
- Last Update: March 2, 2004
-=======================================================================
-
-This file contains some handy info regarding U-Boot and the AMCC
-Ocotea 440gx evaluation board. See the README.ppc440 for additional
-information.
-
-
-SWITCH SETTINGS & JUMPERS
-==========================
-
-Here's what I've been using successfully. If you feel inclined to
-change things ... please read the docs!
-
-DIPSW U46 U80
-------------------------
-SW 1 off off
-SW 2 on off
-SW 3 off off
-SW 4 off off
-SW 5 off off
-SW 6 on on
-SW 7 on off
-SW 8 on off
-
-J41: strapped
-J42: open
-
-All others are factory default.
-
-
-I2C Information
-=====================
-
-See README.ebony for information.
-
-PCI
-===========================
-
-Untested at the time of writing.
-
-PPC440GX Ethernet EMACs
-===========================
-
-All EMAC ports have been tested and are known to work
-with EPS Group 4.
-
-Special note about the Cicada CIS8201:
- The CIS8201 Gigabit PHY comes up in GMII mode by default.
- One must hit an extended register to allow use of RGMII mode.
- This has been done in the 440gx_enet.c file with a #ifdef/endif
- pair.
-
-AMCC does not store the EMAC ethernet addresses within their PIBS bootloader.
-The addresses contained in the config header file are from my particular
-board and you _*should*_ change them to reflect your board either in the
-config file and/or in your environment variables. I found the addresses on
-labels on the bottom side of the board.
-
-
-BDI2k or JTAG Debugging
-===========================
-
-For ease of debugging you can swap the small boot flash and external SRAM
-by changing U46:3 to on. You can then use the sram as your boot flash by
-loading the sram via the jtag debugger.
-
-
-Regards,

-------------------------------------------
-Installation of U-Boot using PIBS firmware
-------------------------------------------
-
-This document describes how to install U-Boot on the Ocotea PPC440GX
-Evaluation Board. We do not erase the PIBS firmware but install U-Boot in the
-soldered FLASH. After this you should be able to switch between PIBS and
-U-Boot via the switch U46 SW1. Please check that SW1 is off (= open) before
-continuing.
-
-Connect to the serial port 0 (J11 lower) of the Ocotea board using the cu
-program. See the hints for configuring cu above. Make sure you can
-communicate with the PIBS firmware: reset the board and hit ENTER a couple of
-times until you see the PIBS prompt (PIBS $). Then proceed as follows:
-
-
-Read MAC Addresses from PIBS
-----------------------------
-
-To read the configured MAC addresses available on your Ocotea board please use
-the following commands:
-
-PIBS $ echo $hwdaddr0
-000173017FE3
-PIBS $ echo $hwdaddr1
-000173017FE4
-PIBS $ echo $hwdaddr2
-000173017FE1
-PIBS $ echo $hwdaddr3
-000173017FE2
-
-In U-Boot this is stored in the following environment variables:
-
-* Ethernet Address 0: ethaddr = 000173017FE3 (==> 00:01:73:01:7F:E3)
-* Ethernet Address 1: eth1addr = 000173017FE4 (==> 00:01:73:01:7F:E4)
-* Ethernet Address 2: eth2addr = 000173017FE1 (==> 00:01:73:01:7F:E1)
-* Ethernet Address 3: eth3addr = 000173017FE2 (==> 00:01:73:01:7F:E2)
-
-
-Configure the network interface (ent0 == emac0)
------------------------------------------------
-
-To download the U-Boot image we need to configure the ethernet interface with
-the following commands:
-
-PIBS $ ifconfig ent0 192.168.160.142 netmask 255.255.0.0 up
-PIBS $ set ipdstaddr0=192.168.1.1
-status: writing PIBS variable value to FLASH
-PIBS $ set bootfilename=/tftpboot/ocotea/u-boot.bin
-status: writing PIBS variable value to FLASH
-
-Please insert correct parameters for your configuration (ip-addresses and
-file-location).
-
-
-Program U-Boot into soldered User-FLASH
----------------------------------------
-
-Please make sure to use a newer version of U-Boot (at least 1.1.3), since
-older versions don't support running from user-FLASH.
-
-To program U-Boot into the soldered user-FLASH use the following command:
-
-PIBS $ storefile bin eth 0xffbc0000
-
-This commands loads the file vis ethernet into ram and copies it into the
-user-FLASH.
-
-
-Switch to U-Boot
-----------------
-
-Now you can turn your board off and switch SW1 (U46) to on (= closed). After
-powering the board you should see the following message:
-
-U-Boot 1.1.3 (Apr 5 2005 - 22:59:57)

+Required properties:
+- compatible : Should be "xlnx,zynq-qspi-1.0".
+- reg : Physical base address and size of QSPI registers map.
+- interrupts : Property with a value describing the interrupt
+ number.
+- interrupt-parent : Must be core interrupt controller
+- clock-names : List of input clock names - "ref_clk", "pclk"
+ (See clock bindings for details).
+- clocks : Clock phandles (see clock bindings for details).
+
+Optional properties:
+- num-cs : Number of chip selects used.
+
+Example:
+ qspi@e000d000 {
+ compatible = "xlnx,zynq-qspi-1.0";
+ clock-names = "ref_clk", "pclk";
+ clocks = <&clkc 10>, <&clkc 43>;

+ interrupts = <0 19 4>;
+ num-cs = <1>;
