This adds Linux booting to the SPL
This depends on CONFIG_MACH_TYPE patch by Igor Grinberg
(http://article.gmane.org/gmane.comp.boot-loaders.u-boot/105809)
Related CONFIGs:
CONFIG_SPL_OS_BOOT
Activates/Deactivates the OS booting feature
CONFIG_SPL_OS_BOOT_KEY
defines the IO-pin number u-boot switch - if pressed u-boot is
booted
CONFIG_SYS_NAND_SPL_KERNEL_OFFS
Offset in NAND of direct boot kernel image to use in SPL
CONFIG_SYS_SPL_ARGS_ADDR
Address where the kernel boot arguments are expected - this is
normaly RAM-begin + 0x100

The patch below fixes device enumeration through the U-Boot API.
Device enumeration crashes when the system in question doesn't
have any RAM mapped to address zero (I discovered this on a
BeagleBone board), since the enumeration calls get_dev with a
NULL ifname sometimes which then gets passed down to strncmp().
This fix simply ensures that get_dev returns NULL when invoked
with a NULL ifname.

Change the parent UART clock to be PLL2, so that U-boot can also boot
a Freescale 2.6.35 kernel for mx53.
FSL kernel and U-boot changed the UART parent from PLL3 to PLL2 to avoid
conflicts with IPU clocks, so that the video resolution can be changed
without affecting the UART clock.
On a 2.6.35 kernel the serial console is messed up after IPU driver is loaded
and this patch fixes this problem.
Tested on a mx53loco board booting a FSL kernel and also a mainline kernel.

After booting mx6qsabrelite from POR the following is reported:

This is because both the POR and WDOG bits are set after reset.

This is needed to support Freescale-supplied userspaces.
At the moment, both the IPU and VPU libraries provided by Freescale
in the "imx-lib" package contain routines which scrape the system
revision from /proc/cpuinfo. In the VPU library, this information is
used to load the proper firmware, allowing a single binary to be used
across various i.MX processors.

The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).
The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().
Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.
If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.
