Since now the generic console_t structure holds the UART base address as
well, let's use that generic location and drop the UART driver specific
data structure at all.

Tegra210 SoCs need the sc7entry-fw to enter System Suspend mode,
but there might be certain boards that do not have this firmware
blob. To stop the NS world from issuing System suspend entry
commands on such devices, we ned to disable System Suspend from
the PSCI "features".

This patch removes the System suspend handler from the Tegra PSCI
ops, so that the framework will disable support for "System Suspend"
from the PSCI "features".

The PMC driver is used only by Tegra210 and Tegra132 platforms. This
patch removes pmc.c from the common makefile and moves it to the
platform specific makefiles.

As a result, the PMC code from common code has been moved to Tegra132
and Tegra210 platform ports.

This patch removes all the weakly defined PSCI handlers defined

This patch converts the weakly defined platform setup handlers into
actual platform specific handlers to improve code coverage numbers
and some MISRA defects.

The weakly defined handlers never get executed thus resulting in
lower coverage - function, function calls, statements, branches
and pairs.

This patch introduces the 'plat_enable_console' handler to allow
the platform to enable the right console. Tegra194 platform supports
multiple console, while all the previous platforms support only one
console.

For Tegra194 platforms, the previous bootloader checks the platform
config and sets the uart-id boot parameter, to 0xFE. On seeing this
boot parameter, the platform port uses the proper memory aperture
base address to communicate with the SPE. This functionality is
currently protected by a platform macro, ENABLE_CONSOLE_SPE.

The platform code generates the power domain tree. The handler to
retrieve the tree should also reside in the platform code.

This patch moves the plat_get_power_domain_tree_desc() to the
individual platforms.

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: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("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.

Commit fdb1964 ("xlat: Introduce
MAP_REGION2() macro") added a granularity field to mmap_region_t.

Tegra platforms were using the v2 xlat_tables implementation in
common/tegra_common.mk, but v1 xlat_tables.h headers in soc/*/plat_setup.c
where arrays are being defined. This caused the next physical address to
be read as granularity, causing EINVAL error and triggering an assert.

Consistently use xlat_tables_v2.h header to avoid this.

Fixes ARM-software/tf-issues#548.

Tegra chips support multiple FIQ interrupt sources. These interrupts
are enabled in the GICD/GICC interfaces by the tegra_gic driver. A
new FIQ handler would be added in a subsequent change which can be
registered by the platform code.

This patch adds the GIC programming as part of the tegra_gic_setup()
which now takes an array of all the FIQ interrupts to be enabled for
the platform. The Tegra132 and Tegra210 platforms right now do not
register for any FIQ interrupts themselves, but will definitely use
this support in the future.

well as the crash console on Tegra platforms. The controller ID to

the base addresses might change across Tegra chips.
