Michal Simek 18ffc0cce4 microblaze: Setup dependencies for ASM optimized lib functions
The patch:
"microblaze: Setup proper dependency for optimized lib functions"
(sha1: 7b6ce52be3)
didn't setup all dependencies properly.
Optimized lib functions in C are also present for little endian
and optimized library functions in assembler are implemented only for
big endian version.

config OPT_LIB_FUNCTION
bool "Optimalized lib function"
default y
help
Allows turn on optimalized library function (memcpy and memmove).
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.
config OPT_LIB_ASM
bool "Optimalized lib function ASM"
depends on OPT_LIB_FUNCTION && (XILINX_MICROBLAZE0_USE_BARREL = 1)
depends on CPU_BIG_ENDIAN
default n
help
Allows turn on optimalized library function (memcpy and memmove).
Function are written in asm code.
