The BL1 stage setup code for ARM platforms sets up the SP805 watchdog
controller as the secure watchdog. But not all ARM platforms use SP805
as the secure watchdog controller.
So introduce two new ARM platform code specific wrapper functions to
start and stop the secure watchdog. These functions then replace the
calls to SP805 driver in common BL1 setup code. All the ARM platforms
implement these wrapper functions by either calling into SP805 driver
or the SBSA watchdog driver.

This changes the auth_img_desc_t struct to have pointers to struct
arrays instead of struct arrays. This saves memory as many of these
were never used, and can be NULL pointers. Note the memory savings are
only when these arrays are not initialised, as it is assumed these
arrays are fixed length. A possible future optimisation could allow for
variable length.

When Trusted Board Boot is enabled, we need to specify the Chain of
Trust (CoT) of the BL1 and BL2 images. A CoT consists of an array
of image descriptors. The authentication module assumes that each
image descriptor in this array is indexed by its unique image
identifier. For example, the Trusted Boot Firmware Certificate has to
be at index [TRUSTED_BOOT_FW_CERT_ID].
Unique image identifiers may not necessarily be consecutive. Also,
a given BL image might not use all image descriptors. For example, BL1
does not need any of the descriptors related to BL31. As a result, the
CoT array might contain holes, which unnecessarily takes up space in
the BL binary.
Using pointers to auth_img_desc_t structs (rather than structs
themselves) means these unused elements only use 1 pointer worth of
space, rather than one struct worth of space. This patch also changes
the code which accesses this array to reflect the change to pointers.
Image descriptors not needed in BL1 or BL2 respectively are also
ifdef'd out in this patch. For example, verifying the BL31 image is
the responsibility of BL2 so BL1 does not need any of the data
structures describing BL31.

ARMv7 and Cortex-A32(ARMv8/aarch32) uses "arm-linux-gnueabi" toolchain which
has both soft-float and hard-float variants and so there could be scenarios
where soft-float toolchain is used.Even though TF-A documentation recommends
to use hard-float toolchain for aarch32 but there are external projects where
we cannot mandate the selection of toolchain and for those projects at least
the build should not fail.
Current TF-A source fails to build with soft-float toolchain because assembler
does not recognizes "vmsr" instruction which is required to enable floating
point unit.
To avoid this piece of code being compiled with soft-float toolchain add
predefined macro guard " __SOFTFP__" exposed by soft-float toolchain.

ARMv8.3-PAuth adds functionality that supports address authentication of
the contents of a register before that register is used as the target of
an indirect branch, or as a load.
This feature is supported only in AArch64 state.
This feature is mandatory in ARMv8.3 implementations.
This feature adds several registers to EL1. A new option called
CTX_INCLUDE_PAUTH_REGS has been added to select if the TF needs to save
them during Non-secure <-> Secure world switches. This option must be
enabled if the hardware has the registers or the values will be leaked
during world switches.
To prevent leaks, this patch also disables pointer authentication in the
Secure world if CTX_INCLUDE_PAUTH_REGS is 0. Any attempt to use it will
be trapped in EL3.

Armv8.5 introduces the field CSV2 to register ID_AA64PFR0_EL1. It can
have the following 3 values:
- 0: Branch targets trained in one hardware described context may affect
speculative execution in a different hardware described context. In
some CPUs it may be needed to apply mitigations.
- 1: Branch targets trained in one hardware described context can only
affect speculative execution in a different hardware described
context in a hard-to-determine way. No mitigation required.
- 2: Same as 1, but the device is also aware of SCXTNUM_ELx register
contexts. The TF doesn't use the registers, so there is no
difference with 1.
The field CSV2 was originally introduced in the TRM of the Cortex-A76
before the release of the Armv8.5 architecture. That TRM only mentions
the meaning of values 0 and 1. Because of this, the code only checks if
the field has value 1 to know whether to enable or disable the
mitigations.
This patch makes it aware of value 2 as well. Both values 1 and 2
disable the mitigation, and 0 enables it.

This reverts commit 2f37046524 ("Add support for the SMC Calling
Convention 2.0").
SMCCC v2.0 is no longer required for SPM, and won't be needed in the
future. Removing it makes the SMC handling code less complicated.
The SPM implementation based on SPCI and SPRT was using it, but it has
been adapted to SMCCC v1.0.

ARMv8.4-TTST (Small Translation tables) relaxes the lower limit on the
size of translation tables by increasing the maximum permitted value
of the T1SZ and T0SZ fields in TCR_EL1, TCR_EL2, TCR_EL3, VTCR_EL2 and
VSTCR_EL2.
This feature is supported in AArch64 state only.
This patch adds support for this feature to both versions of the
translation tables library. It also removes the static build time
checks for virtual address space size checks to runtime assertions.

On ARM platforms, the BL2 memory can be overlaid by BL31/BL32. The memory
descriptors describing the list of executable images are created in BL2
R/W memory, which could be possibly corrupted later on by BL31/BL32 due
to overlay. This patch creates a reserved location in SRAM for these
descriptors and are copied over by BL2 before handing over to next BL
image.
Also this patch increases the PLAT_ARM_MAX_BL2_SIZE for juno when TBBR
is enabled.

Valid addresses for GICR base are always a set calculable distance from
the GICD and is based on the number of cores a given instance of GICv3 IP
can support. The formula for the number of address bits is given by the
ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to
one for GICR instances. Holes in the GIC address space are also
guaranteed to safely return 0 on reads. This allows us to support runtime
detection of the GICR base address by starting from GIC base address plus
BIT(18) and walking until the GICR ID register (IIDR) is detected. We
stop searching after BIT(20) to prevent searching out into space if
something goes wrong. This can be extended out if we ever have a device
with 16 or more cores.

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.

The Armv8.5 extensions introduces PSTATE.SSBS (Speculation Store Bypass
Safe) bit to mitigate against Variant 4 vulnerabilities. Although an
Armv8.5 feature, this can be implemented by CPUs implementing earlier
version of the architecture.
With this patch, when both PSTATE.SSBS is implemented and
DYNAMIC_WORKAROUND_CVE_2018_3639 is active, querying for
SMCCC_ARCH_WORKAROUND_2 via. SMCCC_ARCH_FEATURES call would return 1 to
indicate that mitigation on the PE is either permanently enabled or not
required.
When SSBS is implemented, SCTLR_EL3.DSSBS is initialized to 0 at reset
of every BL stage. This means that EL3 always executes with mitigation
applied.
For Cortex A76, if the PE implements SSBS, the existing mitigation (by
using a different vector table, and tweaking CPU ACTLR2) is not used.

Initial Spectre Variant 1 mitigations (CVE-2017-5753).
A potential speculative data leak was found in PSCI code, this depends
on a non-robust implementation of the `plat_get_core_pos_by_mpidr()`
function. This is considered very low-risk. This patch adds a macro to
mitigate this. Note not all code paths could be analyzed with current
tools.
Add a macro which makes a variable 'speculation safe', using the
__builtin_speculation_safe_value function of GCC and llvm. This will be
available in GCC 9, and is planned for llvm, but is not currently in
mainline GCC or llvm. In order to implement this mitigation the compiler
must support this builtin. Support is indicated by the
__HAVE_SPECULATION_SAFE_VALUE flag.
The -mtrack-speculation option maintains a 'tracker' register, which
determines if the processor is in false speculation at any point. This
adds instructions and increases code size, but avoids the performance
impact of a hard barrier.
Without the -mtrack-speculation option, __builtin_speculation_safe_value
expands to a
ISB
DSB SY
sequence after a conditional branch, before the
speculation safe variable is used. With -mtrack-speculation a
CSEL tracker, tracker, XZR, [cond];
AND safeval,tracker;
CSDB
sequence is added instead, clearing the vulnerable variable by
AND'ing it with the tracker register, which is zero during speculative
execution. [cond] are the status flags which will only be true during
speculative execution. For more information on
__builtin_speculation_safe_value and the -mtrack-speculation option see
https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability/compiler-support-for-mitigations
The -mtracking option was not added, as the performance impact of the
mitigation is low, and there is only one occurence.

- `mmap_add_dynamic_region_alloc_va` it adds a region the same way as

- `mmap_add_alloc_va` takes an array of non const `mmap_region_t`,

their `base_va` field. A helper macro has been created to help create

0x80000000 fits in a unsigned long int, i.e. a 32-bit value). When
summing them up, the result overflows the maximum value that can be
encoded in a 32-bit value so it wraps around and does not result in
the expected value.
This patch changes the suffix of these constants into ULL so that they
always are 64-bit values.

fdtw_read_cells() can only read one or two cells, sometimes it may be
needed to read more cells from one property.
