The `bl1_init_bl2_mem_layout()` API is now deprecated. The default weak
implementation of `bl1_plat_handle_post_image_load()` calculates the
BL2 memory layout and populates the same in x1(r1). This ensures
compatibility for the deprecated API.

This patch migrates the ARM Standard platforms to the new BL
handover interface. The arm_blx_early_platform_setup() functions
are also modified to take in 4 arguments. The `ARM_BL31_PLAT_PARAM_VAL`
value passed to BL31 from BL2 is now in arg3 in preparation of dynamic
configuration arguments.

This patch introduces a new BL handover interface. It essentially allows
passing 4 arguments between the different BL stages. Effort has been made
so as to be compatible with the previous handover interface. The previous
blx_early_platform_setup() platform API is now deprecated and the new
blx_early_platform_setup2() variant is introduced. The weak compatiblity
implementation for the new API is done in the `plat_bl_common.c` file.
Some of the new arguments in the new API will be reserved for generic
code use when dynamic configuration support is implemented. Otherwise
the other registers are available for platform use.

This patch updates the `fiptool` and `cert_create` for the
`hw_config` and `tb_fw_config` dynamic configuration files.
The necessary UUIDs and OIDs are assigned to these files and
the `cert_create` is updated to generate appropriate hashes
and include them in the "Trusted Boot FW Certificate". The
`fiptool` is updated to allow the configs to be specified
via cmdline and included in the generated FIP.

This patch adds an argument to bl1_plat_post/pre_image_load() APIs
to make it more future proof. The default implementation of
these are moved to `plat_bl1_common.c` file.

These APIs are now invoked appropriately in the FWU code path prior
to or post image loading by BL1 and are not restricted
to LOAD_IMAGE_V2.

The patch also reorganizes some common platform files. The previous
`plat_bl2_el3_common.c` and `platform_helpers_default.c` files are
merged into a new `plat_bl_common.c` file.

NOTE: The addition of an argument to the above mentioned platform APIs
is not expected to have a great impact because these APIs were only
recently added and are unlikely to be used.

drivers:ufs: fix hynix ufs bug with quirk on hi36xx SoC

Hynix ufs has deviations on hi36xx platform which will result
in ufs bursts transfer failures at a very low probability.

To fix the problem, the Hynix device must set the register
VS_DebugSaveConfigTime to 0x10, which will set time reference

ARM Platforms: Add assertion for BL2_BASE

The Arm Trusted Firmware is built by default for ARMv8-A version 8.0.
However, the Foundation FVP runs by default in the highest version of
the architecture it supports. This causes problems when trying to run
the Arm Trusted Firmware on it.

This patch adds a note to the User Guide about this problem.

Previously the definition of `_tzc_read_peripheral_id()` was wrapped

hikey960: avoid hardcode on uart port

Commit fdb1964c

 ("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.

EHF: Fix priority check

ARM platforms: Fix console address for flush

Remove URLs from comments

optee: print header info before validate

According to the SMC Calling Convention (ARM DEN0028B):

    The Unknown SMC Function Identifier is a sign-extended value of
    (-1) that is returned in R0, W0 or X0 register.

The value wasn't sign-extended because it was defined as a 32-bit
unsigned value (0xFFFFFFFF).

SMC_PREEMPT has been redefined as -2 for the same reason.

NOTE: This might be a compatibility break for some AArch64 platforms
that don't follow the previous version of the SMCCC (ARM DEN0028A)
correctly. That document specifies that only the bottom 32 bits of the
returned value must be checked. If a platform relies on the top 32 bits
of the result being 0 (so that SMC_UNK is 0x00000000FFFFFFFF), it will
have to fix its code to comply with the SMCCC.

This fixes all defects according to MISRA Rule 3.1: "The character
sequences /* and // shall not be used within a comment". This affects
all URLs in comments, so they have been removed:

- The link in `sdei_state.c` can also be found in the documentation file
  `docs/sdei.rst`.

- The bug that the file `io_fip.c` talks about doesn't affect the
  currently supported version of GCC, so it doesn't make sense to keep
  the comment. Note that the version of GCC officially supported is the
  one that comes with Linaro Release 17.10, which is GCC 6.2.

- The link in `tzc400.c` was broken, and it didn't correctly direct to
  the Technical Reference Manual it should. The link has been replaced
  by the title of the document, which is more convenient when looking
  for the document.

Function plat_ic_get_pending_interrupt_type() should return interrupt
type, not id. The function is used in aarch64 exception handling and
currently the irq/fiq forwarding fails if a secure interrupt happens while

The qemu-specific gic file does not contain any extra functionality so it
can be removed and common file can be used instead.
