This patchset enhaces the recently added Orion Timer driver to support
all other Kirkwood & 32bit MVEBU Armada platforms. Additionally, this
timer support is then enabled per default for those platforms, so that
the board config files don't need to be changed. Also necessary is
some dts hacking, so that the timer DT node is available in early
U-Boot stages.

I've successfully tested this patchset on an Armada XP board. Additional
test on other boards and platforms are very welcome and necessary.

Thanks,
Stefan

I've also discovered that the timer command (CONFIG_CMD_TIMER) was
broken at some time in the past. It does not keep time correctly
(lagging realtime badly), with or without this patch set . I think we
would want to investigate that issue later.

The sleep command works perfectly. Therefore,
