+ppcboot for a CU824 board
+---------------------------
+
+CU824 has two banks of flash 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 not embedded in the U-Boot code
+and is located in flash separately from U-Boot, at the address of
+0xFF008000.
