Running optee_test failed because SEC_DRAM0_SIZE is too small. Previous
is 2 MB. We enlarge it to 11 MB for passing the test. Also we reduce
the NS_DRAM0_SIZE from 13MB to 4MB so that the whole section is still
fit in 16MB.
This commit also modified the document to reflect the changes we've
made in code.

Implement minimal interrupt routing functions. All interrupts are
treated as non-secure interrupts to be handled by the non-secure world.
Add note to the documentation about disabling FIQs qhen using OP-TEE
with Linux.

The plat_arm_mmap variable is already declared in plat_arm.h, which is
included from plat/arm/common/arm_common.c.
Similarly, plat_arm.h declares the 'plat_arm_psci_pm_ops' variable, which
does not need to be declared again in plat/arm/common/arm_pm.c.
The duplication was not compliant with MISRA rule 8.5.

These directives are only used when stabs debugging information
is used, but we use ELF which uses DWARF debugging information.
Clang assembler doesn't support these directives, and removing
them makes the code more compatible with clang.

The H6 is Allwinner's most recent SoC. It shares most peripherals with the
other ARMv8 Allwinner SoCs (A64/H5), but has a completely different memory
map.
Introduce a separate platform target, which includes a different header
file to cater for the address differences. Also add the new build target
to the documentation.
The new ATF platform name is "sun50i_h6".

So far we already support booting on two different SoCs, and we will

This can be later used to runtime detect certain properties.
Also print the SoC name to the console, to give valuable debug information.

The "#ifdef SUNXI_SPC_BASE" guard was meant to allow the build on SoCs
without a Secure Peripherals Controller, so that we skip that part of
the security setup. But in the current position this will trigger a
warning about an unused variable.
Simply move the guard one line up to cover the variable as well.

Having an active stack while enabling MMU has shown coherency problems.
This patch builds on top of translation library changes that introduces
MMU-enabling without using stacks.
Previously, with HW_ASSISTED_COHERENCY, data caches were disabled while
enabling MMU only because of active stack. Now that we can enable MMU
without using stack, we can enable both MMU and data caches at the same
time.
NOTE: Since this feature depends on using translation table library v2,
disallow using translation table library v1 with HW_ASSISTED_COHERENCY.

The file arm_ras.c intended to provide common platform-specific RAS

This patch therefore renames and makes the file specific to FVP. Other
