ARM: mach-shmobile: SH-Mobile G3 support.
This adds preliminary support for the SH-Mobile G-series. The SH-Mobile G-series is a series of ARM/SH multi-core CPUs that aside from the ARM MPU are primarily composed of existing SH IP blocks. This includes initial support for the SH7367 (SH-Mobile G3) CPU and the G3EVM reference board. Only timer, serial console, and NOR flash are supported at this point. Patches for the interrupt controller, pinmux support, clock framework and runtime pm will be submitted as feature patches on top of this.
