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.
I've run some tests with the following 2 Kirkwood boards: Cloud
Engines Pogo V4 88F6192 (with CONFIG_DM_RTC and CONFIG_RTC_EMULATION),
and Marvell Sheevaplug 88F6281 (with CONFIG_DM_RTC and CONFIG_RTC_MV).
It seems that it was either frozen or the timer did not expire at some
subsequent sleep commands. Sometime it happened at 2nd command, some
time at a later sleep command. For example,
=== Pogo V4 (the 1st sleep command works correctly at 10 seconds on my
stopwatch)
U-Boot 2022.10-rc3-00048-g66ccd87a9c-dirty (Aug 30 2022 - 13:38:24 -0700)
Pogoplug V4
Hit any key to stop autoboot: 0
Pogo_V4> sleep 10
Pogo_V4> sleep 31.5
<frozen here>
Does the cmd interface support fractial numbers? Please test again with
31 or other integral numbers.
=== Sheevaplug (RTC battery is old, so the date was not updated, but
the clock seems OK)

Please let me know what I can do (i.e. perhaps running a debug patch).
Please see above. I assume that the fractional numbers result in very
long numbers internally, which result in a frozen / hanging system.
I just tested fractional numbers on another board and hey, it just
works. Learned something new. So we seem to have a problem here. Let
me see, if I can find something.
Thanks,
Stefan
