These hooks are intended to allow one platform to try load
images from alternative places. There is a hook to initialize
the sequence of boot locations and a hook to pass to the next
sequence.

plat_get_my_stack is called from C, so it can't expect argument
registers to be preserved. Stash registers temporarily onto the stack
instead.

plat_set_my_stack is called during early init, when there exists no
stack. Use any register other than argument registers to stash temporary
values.

On ARM platforms before exiting from SP_MIN ensure that
the default console is switched to the runtime serial port.

This API makes sure that all the characters sent to the crash console
are output before returning from it.

These source file definitions should be defined in generic
Makefiles so that all platforms can benefit. Ensure that the
symbols are properly marked as weak so they can be overridden
by platforms.

NOTE: This change is a potential compatibility break for
non-upstream platforms.

The files affected by this patch don't really depend on `xlat_tables.h`.
By changing the included file it becomes easier to switch between the
two versions of the translation tables library.

This patch makes the default MP definitions of plat_get_my_stack()
and plat_set_my_stack() as weak so that they can be overridden by
the AArch32 Secure Payload if it requires.

This patch makes following miscellaneous fixes:
* pl011_console.S: Fixed the bit mask used to check if the
  transmit FIFO is full or empty.
* smcc_macros.S: Added `_fsxc` suffix while updating the SPSR.
  By default the assembler assumes `_fc` suffix which does not
  update all the fields in SPSR. By adding `_fsxc` suffix all
  the fields gets updated.
* platform_helpers.S: Removed the weak definition for
  `plat_my_core_pos()` as this is a mandatory function which
  needs to be defined by all platforms.

This patch adds common changes to support AArch32 state in
BL1 and BL2. Following are the changes:

* Added functions for disabling MMU from Secure state.
* Added AArch32 specific SMC function.
* Added semihosting support.
* Added reporting of unhandled exceptions.
* Added uniprocessor stack support.
* Added `el3_entrypoint_common` macro that can be
  shared by BL1 and BL32 (SP_MIN) BL stages. The
  `el3_entrypoint_common` is similar to the AArch64
  counterpart with the main difference in the assembly
  instructions and the registers that are relevant to
  AArch32 execution state.
* Enabled `LOAD_IMAGE_V2` flag in Makefile for
  `ARCH=aarch32` and added check to make sure that
  platform has not overridden to disable it.

This patch adds AArch32 support for FVP and implements common platform APIs
like `plat_get_my_stack`, `plat_set_my_stack`, `plat_my_core_cos` for AArch32.
Only Multi Processor(MP) implementations of these functions are considered in
this patch. The ARM Standard platform layer helpers are implemented for
AArch32 and the common makefiles are modified to cater for both AArch64 and
AArch32 builds. Compatibility with the deprecated platform API is not
supported for AArch32.
