[PATCH 0/3] Separate generic header usage from ARCH_MULTIPLATFORM

[Jonathan Austin]

The original aim of this series was to restore the ability to build a NOMMU
kernel for Versatile Express, something that was lost when we converted
ARCH_VEXPRESS for ARCH_MULTIPLATFORM.

In order to do this, it is necessary to abstract the use of generic headers
from selection of ARCH_MULTIPLATFORM so that the two can be used separately.
This is necessary becuase building a multiplatform kernel for processors
without and MMU doesn't make sense (it is necessary to hardcode certain mem-map
related data) and the versatile express can host NOMMU processors.

This series performs this separation, and then goes on to add a 'dummy'
ARCH_VEXPRESS_NOMMU platform that can be selected as standalone platform.

Patch 2 was sent to the list as an RFC some time ago where it was ACKd, but
alone is not sufficient to solve the problem, hence this follow-up series.

Since the original single patch was sent I have also selected SPARSE_IRQ for
ARCH_VEXPRESS_NOMMU in that patch.

Jonathan Austin (3):
  ARM: allow platforms to use generic headers without
    ARCH_MULTIPLATFORM
  ARM: nommu: re-enable use of vexpress without ARCH_MULTIPLATFORM
  ARM: vexpress-nommu: add a Makefile.boot to restore single-platform
