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.
