+Changes for U-Boot 0.4.5:
+======================================================================
+
+* Patch by Martin Krause, 17 Jul 2003:
+ add delay to get I2C working with "imm" command and s3c24x0_i2c.c
+
+* Patch by Richard Woodruff, 17 July 03:
+ - Fixed bug in OMAP1510 baud rate divisor settings.
+
+* Patch by Nye Liu, 16 July 2003:
+ MPC860FADS fixes:
+ - add MPC86xADS support (uses MPC86xADS.h)
+ - add 866P/T core support (also MPC859T/MPC859DSL/MPC852T)
+ o PLPRCR changes
+ o BRG changes (EXTAL/XTAL restricted to 10MHz)
+ o don't trust gclk() software measurement by default, depend on
+ CONFIG_8xx_GCLK_FREQ
+ - add DRAM SIMM not installed detection
+ - use more "correct" SDRAM initialization sequence
+ - allow different SDRAM sizes (8xxADS has 8M)
+ - default DER is 0
+ - remove unused MAMR defines from FADS860T.h (all done in fads.c)
+ - rename MAMR/MBMR defines to be more consistent. Should eventually
+ be merged into MxMR to better reflect the PowerQUICC datasheet.
+
+* Patch by Yuli Barcohen, 16 Jul 2003:
+ support new Motorola PQ2FADS-ZU evaluation board which replaced
+ MPC8260ADS and MPC8266ADS
+
