microblaze: Fix ASM optimized code for LE
Michal Simek [Fri, 28 Jan 2011 12:26:54 +0000 (13:26 +0100)]
Microblaze little-endian doesn't support ASM optimized library
functions(memcpy/memmove). Kconfig doens't contain
any information about endian that's why it is necessary to
check it in the source code.
The code is used with barrel shifter is used.
