[PATCH v2 00/14] ARM: OMAP2+: AM43x initial support

Hi,

This series adds initial support for AM43x based SoC's. To boot
AM43x, in addition to these patches, PRCM support is also needed,
which would be posted later as a separate series. DT sources doesn't
have "ti,hwmod" entry - this would be added along with PRCM support.

AM43x SoC's are based on ARM Cortex-A9 with one core. AM43x is similar
to AM335x in it's peripheral capabilities, except a few additional
ones, with many of the peripheral register mapping's similar. AM43x
has a sync timer, which is being used as clocksource. Clockevent used
is 1ms dmtimer.

SoC has PL310 L2 cache, support for it would be added later.

soc_is_am43xx() is introduced to handle AM43x specific details and
soc_is_am437x() is a subclass of it - first member of the class.

AM43x is currently in pre-silicon stage and currently there are no
public documents.

This has been tested on a pre-silicon platform that emulates AM43x SoC
with additional changes on top of this.

AM335x based board (AM335x EVM) has been verfied to boot as earlier
with this series.

Baseline: v3.10-rc3
Dependency: "ARM: OMAP3+: am33xx id: Add new am33xx specific function to check dev_feature"

v2: Major change - use SoC timer's outside of ARM instead of depending
	on ARM SMP local timer for clockevent/source.
