U-Boot for a Musenki M-3/M-1 board---------------------------Musenki M-1 and M-3 have two banks of flash of 4MB or 8MB each.In board's notation, bank 0 is the one at the address of 0xFF800000and bank 1 is the one at the address of 0xFF000000.On power-up the processor jumps to the address of 0xFFF00100, the lastmegabyte of the bank 0 of flash.Thus, U-Boot is configured to reside in flash starting at the address of0xFFF00000. The environment space is located in flash separately fromU-Boot, at the address of 0xFF800000.There is a Davicom 9102A on-board, but I don't have it working yet.U-Boot test results--------------------x.x Operation on all available serial consolesx.x.x CONFIG_CONS_INDEX 1U-Boot 1.1.1 (Nov 20 2001 -
