Antonio Nino Diaz 09d40e0e08 Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Antonio Nino Diaz c3cf06f1a3 Standardise header guards across codebase
All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

Jerome Forissier bde0f3279d qemu: increase PLAT_QEMU_DT_MAX_SIZE to 1 MiB
Since upstream QEMU commit 14ec3cbd7c1e ("device_tree: Increase
FDT_MAX_SIZE to 1 MiB"), which is included in release v2.12.1
and later, BL2 initialization fails with the following error (-3 is
-FDT_ERR_NOSPACE):

 ERROR:   Invalid Device Tree at 0x40000000: error -3

Increase PLAT_QEMU_DT_MAX_SIZE accordingly.

Michalis Pappas f68d22e879 qemu: Add support for stack canary protection
Allow qemu users to enable stack protection. Since the virt platform
does not provide an RNG, use a basic, timer-based, canary generation,
similarly to FVP.

Increase SRAM size and BL2 size to fit images when stack protection is
enabled.

Notice that stack protection is not enabled by default in qemu.

Michalis Pappas c5c7538ec4 qemu: Accessing UART1 causes a data abort
The register address range of UART1 (crash console) are outside the
address ranges mapped for MMIO, resulting to an MMU abort when the
device registers are accessed.

Increase the size of DEVICE1 memory to include the range of UART1.

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.

David Cunado 5724481fdd Update ULL() macro and instances of ull to comply with MISRA
MISRA C-2012 Rule 7.3 violation: lowercase l shall not be used as literal suffixes.

This patch resolves this for the ULL() macro by using ULL suffix instead
of the ull suffix.

Etienne Carriere 765ed9fc55 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.

Etienne Carriere 11d9b20f4b qemu/optee: load OP-TEE pageable part 2MB above OP-TEE image
OP-TEE dedicates the end of the Qemu secure DRAM as specific out-of-TEE
secure RAM. To support this configuration the trusted firmware should
not load OP-TEE resources in this area.

To overcome the issue, OP-TEE pageable image is now loaded 2MByte above
the secure RAM base address.

Etienne Carriere 33dd33f8f0 qemu: fix holding pen mailbox sequence
Before this change, plat_secondary_cold_boot_setup reads wake up mailbox
as a byte array but through 64bit accesses on unaligned 64bit addresses.
In the other hand qemu_pwr_domain_on wakes secondary cores by writing
into a 64bit array.

This change forces the 64bit mailbox format as PLAT_QEMU_HOLD_ENTRY_SIZE
explicitly specifies it.

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
