* 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
