- 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.
