Changes for U-Boot 1.1.4:
======================================================================
+* OMAP242x H4 board update
+ - fix for ES2 differences.
+ - switch to using the cfi_flash driver.
+ - fix SRAM build address.
+ - fix for GP device operation.
+ - unlock SRAM for GP devices.
+ - display more device information.
+ - fix potential deadlock in omap24xx_i2c driver.
+ - fix DLL load values to match dpllout*1 operation.
+ - fix 2nd chip select init for combo DDR device.
+ - add support for CFI Intel 28F256L18 on H4 board.
+ Patch by Richard Woodruff, 03 Mar 2005
+
* Fix formating in include/asm-arm/arch-at91rm9200/AT91RM9200.h
Patch by Steven Scholz, 02 Mar 2005
