* 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
