[PATCH 2/2] qemu: Support MULTI_CONSOLE_API ...

Add support for the new MULTI_CONSOLE_API

Crash information is now displayed in both the runtime and crash consoles,
if a crash occurs after the runtime console has been enabled

Enable MULTI_CONSOLE_API by default on qemu builds

Fixes ARM-software/tf-issues#561

qemu: Support SEPARATE_CODE_AND_RODATA ...

Update qemu_configure_mmu_##_el to add an additional region for code,
marked as MT_CODE | MT_SECURE. Update ro region attributes to NON_EXEC.

Update calls to QEMU_CONFIGURE_BLx_MMU() to pass an additional region for
code. Update calls to pass regions defined in common_def.h.

Increase MAX_MMAP_REGIONS to 10.

Enable SEPARATE_CODE_AND_RODATA by default on QEMU builds.

qemu: support ARMv7/Cortex-A15 ...

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.

Add missing AArch32 assembly macro arm_print_gic_regs from ARM platform
used by the Qemu platform.

Qemu Cortex-A15 model integrates a single cluster with up to 4 cores.

qemu: Add OP-TEE extra image parsing support ...

OP-TEE may have extra images to be loaded. Load them one by one and do
the parsing. In this patch, ARM TF need to load up to 3 images for
OP-TEE: header, pager and pages images. Header image is the info about
optee os and images. Pager image include pager code and data.  Paged
image include the paging parts using virtual memory.

qemu: Add LOAD_IMAGE_V2 support ...

The generic LOAD_IMAGE_V2 framework has been merged and enable for almost
all the arm platform. Because qemu platform doesn't share those common
files with arm, QEMU haven't got this support yet.

This patch add all the necessary code the files for adding LOAD_IMAGE_V2
support on QEMU and enable it as default.

Fix order of remaining platform #includes ...

This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions to this change in order to retain
header groupings and where there are headers within #if statements.

Replace some memset call by zeromem ...

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.

Move BL_COHERENT_RAM_BASE/END defines to common_def.h ...

We have lots of duplicated defines (and comment blocks too).
Move them to include/plat/common/common_def.h.

While we are here, suffix the end address with _END instead of
_LIMIT.  The _END is a better fit to indicate the linker-derived
real end address.
