* Patch by Yuli Barcohen, 4 Mar 2004:

Fix problems with GCC 3.3.x which changed handling of global
  variables explicitly initialized to zero (now in .bss instead of
  .data as before).

* Patch by Leon Kukovec, 02 Mar 2004:
  add strswab() to fix IDE LBA capacity, firmware and model numbers
  on little endian machines

* Patch by Masami Komiya, 02 Mar 2004:
  - Remove get_ticks() from NFS code
  - Add verification of RPC transaction ID

* Patch by Pierre Aubert, 02 Mar 2004:
  cleanup for IDE and USB drivers for MPC5200

IBM Ocotea Board
Last Update: March 2, 2004
=======================================================================
This file contains some handy info regarding U-Boot and the IBM
Ocotea 440gx evalutation 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.
IBM 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,
--Travis
