ppcboot for a CU824 board---------------------------CU824 has two banks of flash 8MB each. In board's notation, bank 0 isthe one at the address of 0xFF800000 and bank 1 is the one at theaddress of 0xFF000000. On power-up the processor jumps to the addressof 0xFFF00100, the last megabyte of the bank 0 of flash. Thus,U-Boot is configured to reside in flash starting at the address of0xFFF00000. The environment space is not embedded in the U-Boot codeand is located in flash separately from U-Boot, at the address of0xFF008000.U-Boot test results--------------------x.x Operation on all available serial consolesx.x.x CONFIG_CONS_INDEX 1ppcboot 0.9.2 (May 13 2001 - 17:56:46)Initializing...
