From: Magnus Damm <damm@opensource.se>
This patch adds initial support for Renesas SH-Mobile AG5.
At this point the AG5 CPU support is limited to the ARM
core, SCIF serial and a CMT timer together with L2 cache
and the GIC. The AG5EVM board also supports Ethernet.
Future patches will add support for GPIO, INTCS, CPGA
and platform data / driver updates for devices such as
IIC, LCDC, FSI, KEYSC, CEU and SDHI among others.
The code in entry-macro.S will be cleaned up when the
ARM IRQ demux code improvements have been merged.
Depends on the AG5EVM mach-type recently registered but
not yet present in arch/arm/tools/mach-types.
As the AG5EVM board comes with 512MiB memory it is
recommended to turn on HIGHMEM.
Many thanks to Yoshii-san for initial bring up.

The current code is way too ugly to live, I'll split out as per MSM and
some of the others, which should make it pretty easy to layer on top of
when your demux changes are merged.

You're also missing a defconfig. Preferably with HIGHMEM enabled.
