Up to now only board-a9m9750dev.c used GPIOs. It just wrote directly into the

The semantic of the REGSET macros didn't change, but hopefully
it's more obvious as it's now.
REGGET is changed to return the unshifted value, analogous to
REGSET. REGGETIM behaves as REGGET before. All callers changed.
..._IDX is used to work with registers that need a parameter like
BBU_GCONFb1.

GENERIC_TIME and GENERIC_CLOCKEVENTS support for the at91rm9200.
- Oneshot mode (used for NO_HZ and high res timers) uses the
alarm to emulate a real oneshot timer; the trickiest bit is
how to avoid some lowlevel races. Thanks to Remy Bohmer for
various fixes to this code.
- Tighten up periodic mode support using the PIT.
- Streamline reads of the 32KHz counter. Thanks to Marc Pignat
for some testing results: the CRTR register has *very* odd
behavior. The reread appears to work around stranger glitches
than just getting an old clock value (which would quickly
self-correct).
- Remove the rounding-up of tick_usec to 10.009 msec (32KiHz/100),
since that no longer acts correct (time increases too fast).
Note that the at91sam9 and at91x40 chips need other solutions,
since they don't have the same system timer module.

Currently find_legacy_serial_ports() can find no serial ports on the
OPB with flattened device tree. Thus no legacy boot console can be
initialized. Just the early udbg console works, which is initialized
with udbg_init_44x_as1 on the UART's physical address specified in
kernel config. This happens because we look for ns16750 serial
devices only and expect opb node to have a device type property. This
patch makes it look for ns16550-compatible devices and use
of_device_is_compatible() for opb in case device type is not
specified.

This makes the kernel use 1TB segments for all kernel mappings and for
user addresses of 1TB and above, on machines which support them
(currently POWER5+, POWER6 and PA6T).
We detect that the machine supports 1TB segments by looking at the
ibm,processor-segment-sizes property in the device tree.
We don't currently use 1TB segments for user addresses < 1T, since
that would effectively prevent 32-bit processes from using huge pages
unless we also had a way to revert to using 256MB segments. That
would be possible but would involve extra complications (such as
keeping track of which segment size was used when HPTEs were inserted)
and is not addressed here.
Parts of this patch were originally written by Ben Herrenschmidt.
