- README on Implementing Linux for the Logic PD LPD7A40X-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.
