SDHI0 card-detect GPIO IRQ on mackarel currently works, because it is the
default configuration of IRQ26. However, we should not rely on this and
should configure the function explicitly.

chclr_write() will use (chan_reg + chclr_offset).
In sh7372 case, DMA1CHCLR is started from 0xfe008220,
and chan_reg is started from 0xfe008020 (= sh7372_dmae0_resources).
Thus, chclr_offset should be (0x220 - 0x20) instead of 0x220.

The STI hardware is based on a single 48-bit 32kHz
counter that together with two individual compare
registers can generate interrupts. There are no
timer operating modes selectable which means that
the timer can not clear on match.

This driver is providing clocksource support for the
48-bit counter. Clockevents are also supported using
the same timer in oneshot mode.

This is V3 of Emma Mobile EV2 SMP support.

At this point only the most basic form of SMP operation
is supported. TWD and CPU Hotplug support is excluded.

Tied to both the Emma Mobile EV2 and the KZM9D board
due to the need to switch on board in platsmp.c and
the newly introduced need for static mappings.

The static mappings are needed to allow hardware
acces early during boot when SMP is initialized.
This early requirement forces us to also map in
the SMU registers.
