# For a description of the syntax of this configuration file,
docs: kbuild: convert docs to ReST and rename to *.rst The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

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"
microblaze: Enable asm optimization only for HW with barrel-shifter 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>

microblaze: Setup dependencies for ASM optimized lib functions The patch: "microblaze: Setup proper dependency for optimized lib functions" (sha1: 7b6ce52be3f86520524711a6f33f3866f9339694) 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.
