Subject[PATCH v3 0/2] arm: add early_ioremap support
Date
This patch adds support for early_ioremap and early_memremap, based
on the existing mechanism in x86. Up to 7 regions of up to 128KB each
can be temporarily mapped in before paging_init, regardless of later
highmem status.

New for this version:
- Addressed feedback on v2
- *cough* corrected early_memremap() to use MT_WRITEALLOC instead
of MT_UNCACHED.
