[microblaze-uclinux] unaligned data access exception

[Jim Van Vorst <jvanvorst@xxxxxxxxx>]

I enabled the unaligned data exception for the microblaze in EDK 9.1, 
since I ran into a chunk of code that assumes unaligned accesses are 
OK.  I wrote a little test app that does an unaligned access and I do in 
fact get the correct result from an unaligned read, but then the 
processor quickly goes off into the weeds.  I can't even talk to it with 
XMD.  I looked around the exception handler in 2.6 and it looks OK to 
me, but it seems that something is not being restored properly.

Any suggestions on this before I dive down the rabbit hole?

Thanks,
Jim
