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 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).

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.

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.
