* 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: add POST support for the MIP405 board
