I was expecting this patch to convert existing #define's to c struct's
I was not expecting it to add new features.
The features should be broken out into their own patch.
Specifically at91_matrix

These are significant enough changes that you should
append a copyright to them.

This looks like a new feature that needs its own patch

This is also used in at91_pdc.h
Multiple files in the next patches use it as well.
Please review the above reference to memsetup.S

This #if () construct is awkward.
 From above it does ot look like either the AT91_MATRIX_MASTER or
AT91_MATRIX_SLAVE is ever >= 16.
These should be reduced

The board specific element names are also awkward.
Please try to reduce this.

Maybe have seperate headers per board?
This is the way the kernel does it.

This is only used by at91_spi.h's c structure.
It seems like these elements should just be appended to the at91_spi_t
Please move them.

It would be better if the '4' case was an explicit list of
boards like 3 & 5 and the #else case was
#error "Error unsupported AT91_PIO_PORTS"
or something like this.

Is this necessary?
You are packing arguments that you are passing to the gpio functions.
It would be better if there were seperate port, pin parameters than
combining and then uncombining.
Please change this.
