0a672d494d arm: Add Prep subcommand support to bootm
Adds prep subcommand to bootm implementation of ARM. When bootm is called
with the subcommand prep the function stops right after ATAGS creation and
before announce_and_cleanup.

This is used in command "cmd_spl export"

379c19ab70 omap-common/spl: Add linux boot to SPL
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

67ee3dd35e mx53: Make PLL2 to be the parent of UART clock
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.

70db4212fc sandbox: add getopt support
This adds simple command-line parsing to sandbox. The idea is that it
sets up the state with options provided, and this state can then be
queried later, as needed.

New flags are declared with the SB_CMDLINE_OPT_SHORT helper macro,
pointers are automatically gathered up in a special section, and
then the core code takes care of gathering them up and processing
at runtime.  This way there is no central place where we have to
store a list of flags with ifdefs.

6fb6207821 sandbox: add concept of sandbox state
The state exists through the life of U-Boot. It can be adjusted by command
line options and perhaps later through a config file.  It is available to
U-Boot through state_...() calls (within sandbox code).

The primary purpose of this is to contain the "hardware" state.  It should
only be used by sandbox internal code.
