+
+The configuration for the AMCC 440EP eval board "Bamboo" was changed
+to only use 384 kbytes of FLASH for the U-Boot image. This way the
+redundant environment can be saved in the remaining 2 sectors of the
+same flash chip.
+
+Caution: With an upgrade from an earlier U-Boot version the current
+environment will be erased since the environment is now saved in
+different sectors. By using the following command the environment can
+be saved after upgrading the U-Boot image and *before* resetting the
+board:
+
+setenv recover_env 'prot off FFF80000 FFF9FFFF;era FFF80000 FFF9FFFF;' \
+ 'cp.b FFF60000 FFF80000 20000'

+ 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 :-)
+

+
+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.

+------------------------------------------
+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:
