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.

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.
Furthermore support the step 'bootm fake'.

common/board_f: enable setup_board_part1() for MIPS
The variables bd_t:bi_memstart and bd_t:bi_memsize have to be
initialized also on MIPS. Otherwise LMB and cmd_bdinfo do not
correctly work. This currently breaks the booting of FIT images
on MIPS. Enable the board_init_f hook setup_board_part1()

At present in SPL we place the device tree immediately after BSS. This
avoids needing to copy it out of the way before BSS can be used. However on
some boards BSS is not placed with the image - e.g. it can be in RAM if
available.
Add an option to tell U-Boot that the device tree should be placed at the
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.
We should update the code so that it does not use so much BSS.
