[RFC v3 PATCH 00/25] Allow NOMMU for MULTIPLATFORM

Hi,

With transition to MULTIPLATFORM we lost capability to build NOMMU
configurations. Maybe not a big deal, but there is still interest in
building NOMMU configuration apart from M-class cores. Basically, I'm
talking about R-class cores which shares a lot with A-class except
MMU; there was little interest to run A-class with MMU disabled (or
1:1 MMU mapping) as well. By now it is not even possible to build
such configurations without extra patches on top. Another aspect is
that some portion of NOMMU code have been (build) untested for a
while. All these makes it even harder to involve more people in using
NOMMU and build community around that.

This series is trying to make it possible to build NOMMU
configurations. It is done in PATCH 25/25 which allows to select
ARCH_MULTIPLATFORM even for NOMMU. This is controlled with EXPERT
config option. All patches prior 25/25 is an attempt to fix build
failures for NOMMU case. I don't claim they are 100% correct, so I'm
open to suggestion how they can be done in a better way.

It was build tested with allmodconfig and defconfigs [1] with
!MMU. Additionally, I've been running randconfig, so two more patches
have been added compared to RFC v2.
I had to keep following diff on top:

diff --git a/drivers/mtd/nand/orion_nand.c b/drivers/mtd/nand/orion_nand.c

+// asm volatile ("ldrd\t%0, [%1]" : "=&r" (x) : "r" (io_base));
buf64[i++] = x;
}
i *= 8;

Not sure all cases are fixed yet, so keep running randconfig.

Patches can be pulled from Git tree:
