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. |
