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: Invalidate dcache before enabling it

2010-02-08T10:39:18+00:00

We found that on write-trough kernel is necessary to do that invalidation.
One WB is possible to use invalidation too.

microblaze: fix interrupt state restore

2010-02-03T12:17:44+00:00

Interrupts must be disabled while an interrupt state restore
(prep for interrupt return) is in progress.
Code to do this was lost in the port to the mainline kernel.

microblaze: nommu: Don't clobber R11 on syscalls

2009-12-14T07:45:11+00:00

The noMMU syscall trap has a bug that causes R11 to be zero on return to
userland. Remove the extra "save" of R11 responsible for the bug.

Remove reloading of mode indicator because r11 already contains it.

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.
