arm: support Thumb-1 with CONFIG_SYS_THUMB_BUILD

When building a Thumb-1-only target with CONFIG_SYS_THUMB_BUILD,
some files fail to build, most of the time because they include
mcr instructions, which only exist for Thumb-2.

This patch introduces a Kconfig option CONFIG_THUMB2 and uses
it to select between Thumb-2 and ARM mode for the aforementioned
files.

stm32f429-discovery: add CONFIG_SYS_THUMB_BUILD

This target is ARMv7-M therefore can only build for Thumb,
but it did not #define CONFIG_SYS_THUMB_BUILD, so the U-Boot
code did not know it had to build for Thumb(2), not ARM.

This patch is binary-invariant: builds of stm32f429-discovery
with and without this patch were compared and found to differ
only by their U-Boot version strings.

         but argument 5 has type 'size_t'

arm: add support for semihosting for ARMv7M targets

If you enable CONFIG_SEMIHOSTING for STM32F429 target, you will get compile
error looking like this:

arch/arm/lib/semihosting.c: In function 'smh_read':
{standard input}: Assembler messages:
{standard input}:34: Error: invalid swi expression
{standard input}:34: Error: value of 1193046 too large for field of 2 bytes at 0
scripts/Makefile.build:277: recipe for target 'arch/arm/lib/semihosting.o' failed

The source of the problem is "svc #0x123456" instruction. This instruction
can not be encoded using Thumb2 instruction set used by ARMv7M CPUs.
ARM documentation suggests using "bkpt #0xAB" instruction instead [1].
This patch fixes compile errors and adds support for semihosting for
STM32F429 or any other ARMv7M target.
This change was sested on STM32F429-DISCOVERY board using OpenOCD and
"smhload" u-boot command.

MIPS: bootm: rework and fix broken bootm code

The move to 'generic board' as well as changes in the generic
bootm code broke the boot of FIT uImage's. Especially uImage's
with additional initramfs images or FDT's do not work anymore.

Refactor the bootm code to work again with the generic bootm code.

Always relocate ramdisk and FDT in step 'bootm prep' because the
generic bootm code does this only for legacy uImage's.

Move the step 'bootm cmdline' to 'bootm prep' because the Linux
kernel parameters rd_start and rd_size have to be initialized after
the relocation of the ramdisk.

end of the image binary (_image_binary_end) instead of at the end of BSS.

Note: A common reason to place BSS in RAM is to support the FAT filesystem.
