This adds Linux booting to the SPL
This depends on CONFIG_MACH_TYPE patch by Igor Grinberg

Related CONFIGs:
CONFIG_SPL_OS_BOOT
Activates/Deactivates the OS booting feature
CONFIG_SPL_OS_BOOT_KEY

booted
CONFIG_SYS_NAND_SPL_KERNEL_OFFS

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.

Add calls to bootstage before and after relocation, and just
before jumping to the OS.
The idea here is you can call bootstage_report() to get a report.
Additionally, if you define CONFIG_BOOTSTAGE_REPORT then a report is
printed automatically by U-Boot just before jumping to the kernel.

Mainline kernel for OMAP3 doesn't enable L2 cache
It expects L2$ to be enabled by ROM-code/bootloader.
Leaving L2$ enabled can be troublesome in cases where
the L2 cache is not under CP15 control, such as in
Cortex-A9. This problem is explained in detail in
the commit dc7100f408
However, this problem doesn't apply to Cortex-A8
because L2$ in Cortex-A8 is under CP15 control and
hence the generic armv7 maintenance opertions work
for it.
As such we can make an exception for OMAP3 and
leave the L2$ enabled when we jump to kernel. This
is done by removing the strongly-linked implementation
of v7_outer_cache_disable() and allowing it to fall
back to the weakly linked implementation that doesn't
do anything.
