Changes since U-Boot 1.1.1:
======================================================================
+* Clean up tools/bmp_logo.c to not add trailing white space
+
+* Patch by Hinko Kocevar, 21 Aug 2004:
+ - Group common framebuffer functions in common/lcd.c
+ - Group common framebuffer macros and #defines in include/lcd.h
+ - Provide calc_fbsize() for video ATAG
+
* Patch by Sam Song, 21 August 2004:
- Fix a typo in README
- Align "(RO)" output for "flinfo" after "protect on"
- Add RESET support for RPXlite_DW board; adjust CPU:BUS frequency
ratio 1:1 when core frequency less than 50MHz
-* Patches by himba, 21 Aug 2004:
+* Patches by Hinko Kocevar, 21 Aug 2004:
- fix some "use of label at end of compound statement" warnings
- Define type of LCD panel on lubbock board if CONFIG_LCD is used
