Subject: * Patch by Arun Dharankar, 4 Apr 2003:   Add IDMA example code
 (tested on 8260 only)

* Add support for Purple Board (MIPS64 5Kc)

* Add support for MIPS64 5Kc CPUs

* Fix missing setting of "loadaddr" and "bootfile" on ARM and MIPS

* Patch by Denis Peter, 04 Apr 2003:
  - update MIP405-4 board

* Patches by Denis Peter, 03 April 2003:
  - fix PCI IRQs on MPL boards
  - fix two more un-relocated pointer problems

* Fix behaviour of "run" command:
  - print error message iv variable does not exist
  - terminate processing of arguments in case of error

* Patches by Peter Figuli, 10 Mar 2003
  - Add support for BTUART on PXA platform
  - Add support for WEP EP250 (PXA) board

* Fix flash problems on INCA-IP; add tool to allow bruning images  to
  flash using a BDI2000

* Implement fix for I2C Edge Conditions problem for all boards that
  use the bit-banging driver (common/soft_i2c.c)

* Add patches by Robert Schwebel, 31 Mar 2003:
  - csb226 board: bring in sync with innokom/memsetup.S
  - csb226 board: fix MDREFR handling
  - misc doc fixes / extensions
  - innokom board: cleanup, MDREFR fix in memsetup.S, config update
  - add BOOT_PROGRESS to armlinux.c
