Asm code uses barrel-shifter instruction that's why we have to protect cases when HW don't have it. Reported-by: John Linn <john.linn@xilinx.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

They are optimized by using word alignment. This will work
|
|
fine if both source and destination are aligned on the same
|
|
boundary. However, if they are aligned on different boundaries
|
|
shifts will be necessary. This might result in bad performance
|

on MicroBlaze systems without a barrel shifter.
