Subject: Re: [PATCH v3 4/4] ARM: reinsert ARCH_MULTI_V4 Kconfig option

Arnd suggested removing one (or many) of the options:

CPU_ABRT_EV4T
CPU_CACHE_V4WT
CPU_COPY_V4WB
CPU_TLB_V4WBI

However boot is still broken after removing all including CPU_32v4T.

Selecting CPU_SA1100 instead, it boots normally and init works.

The idea is, If you can help figure out what exactly breaks boot, the
patch can be dropped.

>From these tests, I have created two branches ( arch/arm/mm have
replacements for calls to no longer compiled in ):
