Xilinx IP core drivers for RTEMS- diff attached

[Robert S. Grimes]

Hi Greg,

I attempt to build using your patches on a clean install of 4.6.99.3,
and I get this error:

    ibcpu/powerpc'

The "xilemac.h" file certainly does exist!  It seems there's an include
path problem.  I'm going to try and track it down, but I thought you might:
  - know what I did wrong (if it's my mistake), or
  - want to know (if it's a patch problem).

I will let you know what I find on my end.

Thanks!
-Bob
