Cover letter [PATCH 0/2] arm: add early_ioremap support
Quoted 11 lines · Leif Lindholm
early_ioremap()/early_memremap() create temporary virtual mappings in the fixmap region during boot time. Part of the support now exists in core code, but depends on the generic fixmap support.
This set converts arm to use the generic fixmap support, and adds the architecture-specific part of
early_ioremapsupport.The fixmap/kmap changes in 3.15 complicated things slightly compared to previous iterations of these patches - this version works around that by introducing local macros in
arm/mm/highmem.c.

Tested on TC2 and software models, with/without LPAE.
