Optimized library functions are implemented only for little endian.
Setup this dependency via Kconfig.
commit 206d3642d8 ("arch/microblaze: add choice for endianness and
update Makefile") added an option to setup endianess via Kconfig.

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.
