Changes since U-Boot 1.1.4:
======================================================================
+* Update omap5912osk board support
+ - Fix OMAP support that omap5912osk compiles in current source tree
+ - Update with code from "http://omap.spectrumdigital.com/osk5912"
+ to fix problems with DDR initialization
+ - Fix timer setup
+ - Use CFI flash driver and support complete 32MB of onboard flash
+ - Add "print_cpuinfo()" and "checkboard()" functions to display
+ CPU (with frequency) and Board infos
+ Patch by Stefan Roese, 10 May 2006
+
* Fix watchdog issues for ColdFire boards.
* Add M5271EVB board support.
