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 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. Signed-off-by: NMichal Simek <monstr@monstr.eu>

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.

This was intended to allow manual override of CPU settings copied automatically to Kconfig.auto, however it's problematic for several reasons, but mostly: * If the defconfig doesn't have ALLOW_EDIT_AUTO=y, then it's impossible for that defconfig to iverride the values in the kernel source tree. This leads to very strange errors where the kernel is compiled with the wrong CPUFLAGS. Next patch in the series will back out the default in Kconfig.auto to baseline settings, so a kernel built with no default values will at least boot on any hardware, just not make use of additional CPU features.
