microblaze: Fix cache loop function for cache range

2010-02-24T12:18:29+00:00

I create wrong asm code but none test shows that this part of code is wrong.
I am not convinces that were good idea to create asm optimized macros
for caches. The reason is that there is not optimization with previous code
that's why make sense to add old code and do some benchmarking which
functions are faster.

microblaze: Support for WB cache

2009-12-14T07:45:10+00:00

Microblaze version 7.20.d is the first MB version which can be run
on MMU linux. Please do not used previous version because they contain
HW bug.
Based on WB support was necessary to redesign whole cache design.
Microblaze versions from 7.20.a don't need to disable IRQ and cache
before working with them that's why there are special structures for it.

microblaze: Remove ancient and fake microblaze version from cpu_ver table

2009-12-14T07:45:09+00:00

We need to continue with next microblaze PVR version that's why
I have to remove that ancient version. These version strings not match
any versions. From Microblaze v5.00.a is possible to use this style.
I believe that none use ancients versions. If yes they will be just
labeled as unknown version.

microblaze: Extend cpuinfo for support write-back caches

2009-12-14T07:44:58+00:00

There is missing checking agains PVR but this is not important
for now. There are some missing checking too.

microblaze: Fix cache_line_lenght

2009-12-14T07:44:57+00:00

We used cache_line as cache_line_lenght. For this reason
we did cache flushing 4 times longer than was necessary.

microblaze: ftrace: add static function tracer

2009-12-14T07:40:09+00:00

If -pg of gcc is enabled with CONFIG_FUNCTION_TRACER=y. a calling to
_mcount will be inserted into each kernel function. so, there is a
possibility to trace the kernel functions in _mcount.

This patch add the specific _mcount support for static function
tracing. by default, ftrace_trace_function is initialized as
ftrace_stub(an empty function), so, the default _mcount will introduce
very little overhead. after enabling ftrace in user-space, it will jump
to a real tracing function and do static function tracing for us.
