Thanks for submitting this. It has been on the wish list for a while.
My first comment is that information needs to be added to the Users Guide
on
this BSP. Guidance on capabilities, use, and debug is always appreciated by
the
next user. Remember that often this is where search engines and other humans
find out if something is supported.
Comments inline. Hoping others who know this hardware better do a more
technical review.

The RTEMS style would have this more like:
for (...) {
if (...) {
break;
}
}
There is a nearly finished format configuration for clang-format which might
help. Gedare is trying to finish that up.

Someone else should comment on whether this Xilinx file should be in
a location where it is shareable by other BSPs.
Is this file unmodified from the Xilinx provided version? Changes for
RTEMS should be inside conditional like "#ifdef __rtems__" or
