pxa_gpio_mode() is a universal call that fiddles with the GAFR
(gpio alternate function register.)  GAFR does not exist on PXA3
CPUs, but instead the alternate functions are controlled via the
MFP support code.

Platforms are expected to configure the MFP according to their
needs in their platform support code rather than drivers.  We
extend this idea to the GAFR, and make the gpio_direction_*()
functions purely operate on the GPIO level.

This means platform support code is entirely responsible for
configuring the GPIOs alternate functions on all PXA CPU types.

Switch the tps65010 driver into a "new-style" I2C driver, and convert all
of its in-tree users (board support for OSK, H2, H3) accordingly.

That accounts for most of the board-specific code in this driver; the
rest of that code is now moved into board-specific initcalls.

Also remove some of the many now-superfluous #includes.

Newer versions of binutils support --build-id, which adds an ELF
note section called ".note.gnu.build-id" to the output.  On the ARM
kernel build, because there is no explicit mention of this section
in the shipped ld script, this section is placed at vaddr 0x00000000
(whereas the normal kernel text/data typically starts at vaddr
0xc0008000), causing the output of objcopy (Image) to produce a 3G+
file.

This patch makes objcopy strip the .note.gnu.build-id section from
the Image file along with all other note sections, which fixes the
build.

This patch resolves a kexec boot failure that can occur because
no ATAGs are passed in to the kexec'd kernel. Currently the
newly-kexec'd kernel may fail if it requires specific ATAGs, or
it may fail because the fixed memory location at which it expects
to find the ATAGs may contain random data instead of ATAGs.

The patch ensures that any ATAGs passed to the current kernel
at boot time are copied to a static buffer, and are copied back
when kexec copies the new kernel into place. Thus the new
kernel sees the same ATAGs from kexec and the boot loader.

The boot parameters are copied without regard to type, content,
or length -- this patch's scope is limited soley to saving and
restoring a fixed-size block of memory containing the kernel's
boot parameters. Additional functionality to examine, alter, or
replace the ATAGs (using kexec, for example) can be implemented
by manipulating the static buffer containing the preserved ATAGs.

Note: the size of the buffer (1.5KB) is selected to comfortably
hold one of each ATAG type, including a maximum-length command
line and the maximum number of ATAG_MEM structures currently
supported by the kernel. Should an ATAG list exceed that limit,
the list will be silently truncated to that limit (to do other-
wise at that point in the boot process would make a simple
problem exceedingly complicated).

[Note: this is the same patch as 4579, modified to accomodate
the ATAG changes introduced in 2.6.23]

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.
