Wondering about the PPC parallel I/O handling

Hi,

Looking at U-boot's handling of PPC parallel I/O, there are some things I was wondering about:
- There's no module that's responsible of it. Handling is done in the cpu_init module alone (among other things). This means that there's some duplicated code (for instance in the 85xx and 83xx cpu_init modules).
- There's no easy way to read from a port or write to it - one needs to perform some cumbersome actions on the port registers instead of having simple read_port and write_port functions.
- For some reason, in the QE PIO configuration table, there's no field for the port data (relevant for output ports) as it was with CPM2. This requires to setup all initial values manually.

Are there any plans to reform this piece of code?

Regards,
David.
