Changes for U-Boot 1.1.1:
======================================================================
+* Clean up the TQM8xx_YYMHz configurations; allow to use the same
+ binary image for all clok frequencies. Implement run-time
+ optimization of flash access timing based on the actual bus
+ frequency.
+
* Modify KUP4X board configuration to use SL811 driver for USB memory
sticks (including FAT / VFAT filesystem support)
