The QEMU platform has only been used with LOAD_IMAGE_V2=1 for some time
now and bit rot has occurred for LOAD_IMAGE_V2=0. To ease the
maintenance make LOAD_IMAGE_V2=1 mandatory and remove the platform
specific code for LOAD_IMAGE_V2=0.

The codebase was using non-standard headers. It is needed to replace
them by the correct ones so that we can use the new libc headers.

Use the console_pl011_core_* functions directly in the crash console
callbacks.

This bypasses the MULTI_CONSOLE_API for the crash console (UART1), but
allows using the crash console before the C runtime has been initialized
(eg to call ASM_ASSERT). This retains backwards compatibility with respect
to functionality when the old API is used.

Use the MULTI_CONSOLE_API to register UART0 as the boot and runtime
console.

type, not id. The function is used in aarch64 exception handling and
currently the irq/fiq forwarding fails if a secure interrupt happens while

can be removed and common file can be used instead.

Define Qemu AArch32 implementation for some platform functions
(core position, secondary boot cores, crash console). These are
derived from the AArch64 implementation.

BL31 on Qemu is needed only for ARMv8 and later. On ARMv7, BL32 is
the first executable image after BL2.

Support SP_MIN and OP-TEE as BL32: create a sp_min make script target
in Qemu, define mapping for IMAGE_BL32

Minor fix Qemu return value type for plat_get_ns_image_entrypoint().

Qemu model for the Cortex-A15 does not support the virtualization
extension although the core expects it. To overcome the issue, Qemu
ARMv7 configuration set ARCH_SUPPORTS_VIRTUALIZATION to 0.

In the next commit, I need the image name in lowercase because
output files are generally named in lowercase.

Unfortunately, TOOL_ADD_IMG takes the first argument in uppercase
since we generally use uppercase Make variables.

make_helpers/build_macros.mk provides 'uppercase' macro to convert
a string into uppercase, but 'lowercase' does not exist.  We can
implement it if we like, but it would be more straightforward to
change the argument of TOOL_ADD_IMG.

Before this change, plat_secondary_cold_boot_setup reads wake up mailbox

Replace all use of memset by zeromem when zeroing moderately-sized
structure by applying the following transformation:
memset(x, 0, sizeof(x)) => zeromem(x, sizeof(x))

As the Trusted Firmware is compiled with -ffreestanding, it forbids the
compiler from using __builtin_memset and forces it to generate calls to
the slow memset implementation. Zeromem is a near drop in replacement
for this use case, with a more efficient implementation on both AArch32
and AArch64.

One nasty part of ATF is some of boolean macros are always defined
as 1 or 0, and the rest of them are only defined under certain
conditions.

For the former group, "#if FOO" or "#if !FOO" must be used because
"#ifdef FOO" is always true.  (Options passed by $(call add_define,)
are the cases.)

For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because
checking the value of an undefined macro is strange.

Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like
follows:

  $(eval IMAGE := IMAGE_BL$(call uppercase,$(3)))

  $(OBJ): $(2)
          @echo "  CC      $$<"
          $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@

This means, IMAGE_BL* is defined when building the corresponding
image, but *undefined* for the other images.

So, IMAGE_BL* belongs to the latter group where we should use #ifdef
or #ifndef.
