| 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. |
