| 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. |
