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:

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. Signed-off-by:

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.
