- CPLD memory mapping
|
|
|
|
The board designers chose to use high address lines for controlling
|
|
access to the CPLD registers. It turns out to be a big waste
|
|
because we're using an MMU and must map IO space into virtual
|
|
memory. The result is that we have to make a mapping for every
|
|
register.
|
|
|
|
- Serial Console
|
|
|
|
It may be OK not to use the serial console option if the user passes
|
|
the console device name to the kernel. This deserves some exploration.
