Subject: * Patches by Reinhard Meyer, 14 Feb 2004:   - update board/emk tree;
 use common flash driver   - Corrected tested bits in machine check exception
 in cpu/mpc5xxx/traps.c     [adapted for other PPC CPUs -- wd]   - Added
 support for the M48T08 on the EVAL5200 board in rtc/mk48t59.c

* Patch by Jon Diekema, 13 Feb 2004:
  Call show_boot_progress() whenever POST "FAILED" is printed.

* Patch by Nishant Kamat, 13 Feb 2004:
  Add support for TI OMAP1610 H2 Board
  Fixes for cpu/arm926ejs/interrupt.c
       (based on Richard Woodruff's patch for arm925, 16 Oct 03)
  Fix for a timer bug in OMAP1610 Innovator
  Add support for CS0 (ROM)/CS3 (Flash) boot in OMAP1610 Innovator and H2

* Patches by Stephan Linz, 12 Feb 2004:
  - add support for NIOS timer with variable period preload counter value
  - prepare POST framework support for NIOS targets

* Patch by Denis Peter, 11 Feb 2004:
