README on Implementing Linux for the Logic PD LPD7A400-10
=========================================================
- 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.
