| 4 | - CPLD memory mapping |
| 5 | |
| 6 | The board designers chose to use high address lines for controlling |
| 7 | access to the CPLD registers. It turns out to be a big waste |
| 8 | because we're using an MMU and must map IO space into virtual |
| 9 | memory. The result is that we have to make a mapping for every |
| 10 | register. |

| 12 | - Serial Console |
| 13 | |
| 14 | It may be OK not to use the serial console option if the user passes |
| 15 | the console device name to the kernel. This deserves some exploration. |
