Patches by Yasushi Shoji, 29 Jun 2004:
- add empty include/asm-microblaze/processor.h - add to CREDITS and MAINTAINERS - add gd initialization - add MicroBlaze and SUZAKU board to MAKEALL script - add reset support for SUZAKU - add flush_cache() for MicroBlaze - add CFG_FLASH_SIZE to include/configs/suzaku.h since we have fixed size flash memory on SUZAKU
