The two chips are somewhat different, and needs different handling. Adds handing of the dma, dram initialization, hardware settings, io, memory arbiter and pinmux Also moves the dma, dram initialization and io from CRIS v32 common files.

Configures the direction of general port A bits. 1 is out, 0 is in.

This is often totally different depending on the product used.

There are some guidelines though - if you know that only LED's are
|
|
connected to port PA, then they are usually connected to bits 2-4
|
|
and you can therefore use 1c. On other boards which don't have the
|
|
LED's at the general ports, these bits are used for all kinds of
|
|
stuff. If you don't know what to use, it is always safe to put all
|
|
as inputs, although floating inputs isn't good.
