On FVP platforms, for now it is assumed that the normal-world
bootloader is already sitting in its final memory location.
Therefore, BL2 doesn't need to load it and so it doesn't need
to know the extents of the non-trusted DRAM.

Also, don't invalidate the TLBs in disable_mmu() function, it's better
to do it in enable_mmu() function just before actually enabling the
MMU.

Any asynchronous exception caused by the firmware should be handled
in the firmware itself. For this reason, unmask SError exceptions
(and Debug ones as well) on all boot paths. Also route external
abort and SError interrupts to EL3, otherwise they will target EL1.

Global and static variables are expected to be initialised to zero
by default. This is specified by the C99 standard. This patch
removes some unnecessary initialisations of such variables.
It fixes a compilation warning at the same time:
plat/fvp/bl31_plat_setup.c:82:3: warning: missing braces around
initializer [-Wmissing-braces]
section("tzfw_coherent_mem"))) = {0};
^
plat/fvp/bl31_plat_setup.c:82:3: warning: (near initialization for
‘ns_entry_info[0]’) [-Wmissing-braces]
Note that GCC should not have emitted this warning message in the
first place. The C Standard permits braces to be elided around
subaggregate initializers. See this GCC bug report:

blx_plat_arch_setup() should only perform platform-specific
architectural setup, e.g. enabling the MMU. This patch moves
generic architectural setup code out of blx_plat_arch_setup().

- The Foundation FVP is a cut down version of the Base FVP and as
such lacks some components.
- Three FDTs are provided.
fvp-foundation-gicv2legacy-psci:
Use this when setting the Foundation FVP to use GICv2. In this
mode the GIC is located at the VE location, as described in the
VE platform memory map.
fvp-foundation-gicv3-psci :
Use this when setting the Foundation FVP to use GICv3. In this
mode the GIC is located at the Base location, as described in the
Base platform memory map.
fvp-foundation-gicv2-psci :
Use this when setting the Foundation FVP to use GICv3, but Linux
is expected to use GICv2 emulation mode. In this mode the GIC is
located at the Base location, but the GICv3 is used in GICv2
emulation mode.
