This patch moves the 'drivers' and the 'lib' folders out of the
'common' folder. This way the 'common' folder shall contain only
the platform support required for all Tegra platforms.

If the user tries to change BUILD_BASE to put the build products outside
the build tree the compile will fail due to hard coded assumptions that
$BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE))
to rationalize to an absolute path every time and remove the relative
path assumptions.
This patch also adds documentation that BUILD_BASE can be specified by
the user.

This patch moves all GICv2 driver files into new added
'gicv2.mk' makefile for the benefit of the generic driver
which can evolve in the future without affecting platforms.
NOTE: Usage of 'drivers/arm/gic/common/gic_common.c' file
is now deprecated and platforms with GICv2 driver need to
be modified to include 'drivers/arm/gic/v2/gicv2.mk' in
their makefiles.

The previous sequence used by the driver to program the new memory
aperture settings and clear the non-overlapping memory was faulty.
The sequence locked the non-overlapping regions twice, leading to
faults when trying to clear it.
This patch modifies the sequence to follow these steps:
* move the previous memory region to a new firewall register
* program the new memory aperture settings
* clean the non-overlapping memory
This patch also maps the non-overlapping memory as Device memory to
follow guidance from the arch. team.

Hotplug poweron is not working for boot CPU as it's being
triggerred using PMC and not with Flow Controller. This is
happening because "cpu_powergate_mask" is only getting set
for non-boot CPU's as the boot CPU's first bootup follows
different code path. The patch is marking a CPU as ON within
"cpu_powergate_mask" when turning its power domain on
during power on. This will ensure only first bootup on all
CPU's is using PMC and subsequent hotplug poweron will be
using Flow Controller.

The BL3-1 firmware code is stored in TZSRAM on Tegra194 platforms. This
memory loses power when we enter System Suspend and so its contents are
stored to TZDRAM, before entry. This opens up an attack vector where the
TZDRAM contents might be tampered with when we are in the System Suspend
mode. To mitigate this attack the SE engine calculates the hash of entire
TZSRAM and stores it in PMC scratch, before we copy data to TZDRAM. The
WB0 code will validate the TZDRAM and match the hash with the one in PMC
scratch.

ERRATA_A57_829520 disables "indirect branch prediction" for
EL1 on cpu reset, leading to 15% drop in CPU performance
with coremark benchmarks.
Tegra210 already has a hardware fix for ARM BUG#829520,so
this errata is not needed.
This patch disables the errata to get increased performance
numbers.

As bpmp-fw is running at the same time as ATF, and
the mss client reconfiguration sequence involves performing
a hot flush resets on bpmp, there is a chance that bpmp-fw is
trying to perform accesses while the hot flush is active.
Therefore, the mss client reconfigure has been moved to
System Suspend resume fw and bootloader, and it can be
removed from here.

There are chances a denial-of-service attack, if an attacker
removes the SPE firmware from the system. The console driver
would end up waiting for the firmware to respond indefinitely.
The console driver must detect such scenarios and uninit the
interface as a result.
This patch adds a timeout to the interaction with the SPE
firmware and uninits the interface if it times out.

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".

Code complexity is a good indication of maintainability versus
testability of a piece of software.
ISO26262 introduces the following thresholds:
complexity < 10 is accepted
10 <= complexity < 20 has to be justified
complexity >= 20 cannot be accepted
Rationale is that number of test cases to fully test a piece of
software can (depending on the coverage metrics) grow exponentially
with the number of branches in the software.

as accessible only from the secure world. This setting must be
programmed during cold boot and System Resume.

This patch modifies the delay timer driver to switch to the ARM
secure physical timer instead of using Tegra's on-chip uS timer.
The secure timer is not accessible to the NS world and so eliminates
an important attack vector, where the Tegra timer source gets switched
off from the NS world leading to a DoS attack for the trusted world.
This timer is shared with the S-EL1 layer for now, but later patches
will mark it as exclusive to the EL3 exception mode.

This flag warns if anything is declared more than once in the same
scope, even in cases where multiple declaration is valid and changes
nothing.
Consequently, this patch also fixes the issues reported by this
flag. Consider the following two lines of code from two different source
files(bl_common.h and bl31_plat_setup.c):
IMPORT_SYM(uintptr_t, __RO_START__, BL_CODE_BASE);
IMPORT_SYM(unsigned long, __RO_START__, BL2_RO_BASE);
The IMPORT_SYM macro which actually imports a linker symbol as a C expression.
The macro defines the __RO_START__ as an extern variable twice, one for each
instance. __RO_START__ symbol is defined by the linker script to mark the start
of the Read-Only area of the memory map.
Essentially, the platform code redefines the linker symbol with a different
(relevant) name rather than using the standard symbol. A simple solution to
fix this issue in the platform code for redundant declarations warning is
to remove the second IMPORT_SYM and replace it with following assignment
static const unsigned long BL2_RO_BASE = BL_CODE_BASE;
