* Add start-up delay to make sure power has stabilized before

attempting to switch on USB on SX1 board.

* Patch by Josef Wagner, 18 Mar 2004:
  - Add support for MicroSys XM250 board (PXA255)
  - Add support for MicroSys PM828 board (MPC8280)
  - Add support for 32 MB Flash on PM825/826
  - new SDRAM refresh rate for PM825/PM826
  - added support for MicroSys PM520 (MPC5200)
  - replaced Query by Identify command in CPU86/flash.c
    to support 28F160F3B

* Fix wrap around problem with udelay() on ARM920T

* Add support for Macronix flash on TRAB board
