* 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!
+

+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
