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. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Allows the configuration of the timer frequency. It is customary
|
|
to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
|
|
case of low timer frequencies other values may be more suitable.
|
|
SH-Mobile systems using a 32768 Hz RCLK for clock events may want
|
|
to select a HZ value such as 128 that can evenly divide RCLK.
|
|
A HZ value that does not divide evenly may cause timer drift.
