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 0xFF800000 and bank 1 is the one at the address of 0xFF000000. On power-up the processor jumps to the address of 0xFFF00100, the last megabyte of the bank 0 of flash. Thus, U-Boot is configured to reside in flash starting at the address of 0xFFF00000. The environment space is located in flash separately from U-Boot, at the address of 0xFF800000. There is a Davicom 9102A on-board, but I don't have it working yet.
