+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.
