FVPs that model DynamIQ configuration implements all CPUs in a single
cluster. I.e., such models have a single cluster with more than 4 CPUs.
This differs from existing default build configuration for FVP where up
to 4 CPUs are assumed per cluster.
To allow building for DynamIQ configuration, promote the macro
FVP_MAX_CPUS_PER_CLUSTER as a build option to have it set from the build
command line. The value of the build option defaults to 4.

The SCP binaries provided in the 17.10 Linaro release (and onwards)
have migrated to the SCMI/SDS protocols. Therefore, the ARM TF should
now use the corresponding drivers by default.
This patch changes the default value of the CSS_USE_SCMI_SDS_DRIVER
build option to 1 for Juno.

When the MMU is enabled and the translation tables are mapped, data
read/writes to the translation tables are made using the attributes
specified in the translation tables themselves. However, the MMU
performs table walks with the attributes specified in TCR_ELx. They are
completely independent, so special care has to be taken to make sure
that they are the same.
This has to be done manually because it is not practical to have a test
in the code. Such a test would need to know the virtual memory region
that contains the translation tables and check that for all of the
tables the attributes match the ones in TCR_ELx. As the tables may not
even be mapped at all, this isn't a test that can be made generic.
The flags used by enable_mmu_xxx() have been moved to the same header
where the functions are.
Also, some comments in the linker scripts related to the translation
tables have been fixed.

This patch adds TB_FW_CONFIG for FVP and allows FVP
to select the appropriate HW_CONFIG to include in the
fip. The HW_CONFIG for FVP is selected via `FVP_HW_CONFIG_DTS`
build option. The TB_FW_CONFIG specifies the load address of
HW_CONFIG to BL2. Since currently the load address is different
between AARCH32 and AARCH64, 2 separate TB_FW_CONFIGs are
maintained for the 2 modes.

The patch adds the necessary changes to load HW_CONFIG in BL2 for
ARM Platforms :
1. The load address of HW_CONFIG is specified via the `hw_config_addr`
property in TB_FW_CONFIG is loaded by BL1. The `hw_config_max_size`
property defines the maximum size to be expected for the HW_CONFIG.
The `arm_dyn_cfg_helpers.c` and corresponding header implements
utility functions to parse these DT properties defined.
The `arm_dyn_cfg.c` implements wrappers to these helpers to enable
them to be invoked from ARM platform layer.
2. `HW_CONFIG` is added to the `bl2_mem_params_descs[]` array which is
the list of images to be loaded by BL2.
3. The `libfdt` sources are now included when BL2 is built
4. A new helper `populate_next_bl_params_config()` is introduced in
desc_image_load.c to populate the subsequent executable BL images
with the `hw_config` and the corresponding `fw_config` if available.
The `plat_get_next_bl_params()` API for ARM platforms is modified to
invoke this new helper.
5. The implementation of `bl2_early_platform_setup2()` is modified to
consider `arg0` as well in addition to `arg1` passed from BL1.
6. Bump up the BL2 size for Juno to accommodate the inclusion of libfdt.

This patch modifies the bl1_platform_setup() API to load and authenticate
TB_FW_CONFIG in BL1. The load address of the same is passed on to BL2 in
`arg0` of entrypoint info. The fvp_io_storage.c and arm_io_storage.c also
adds entries corresponding to TB_FW_CONFIG. A helper function
`arm_load_tb_fw_config()` is added to load and authenticate TB_FW_CONFIG
if present.

The `bl1_init_bl2_mem_layout()` API is now deprecated. The default weak

compatibility for the deprecated API.

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 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.

Commit fdb1964c34 ("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.

Define Qemu AArch32 implementation for some platform functions
(core position, secondary boot cores, crash console). These are
derived from the AArch64 implementation.
BL31 on Qemu is needed only for ARMv8 and later. On ARMv7, BL32 is
the first executable image after BL2.
Support SP_MIN and OP-TEE as BL32: create a sp_min make script target
in Qemu, define mapping for IMAGE_BL32
Minor fix Qemu return value type for plat_get_ns_image_entrypoint().
Qemu model for the Cortex-A15 does not support the virtualization
extension although the core expects it. To overcome the issue, Qemu
ARMv7 configuration set ARCH_SUPPORTS_VIRTUALIZATION to 0.
Add missing AArch32 assembly macro arm_print_gic_regs from ARM platform
used by the Qemu platform.

Currently, the xlat region of the on-chip SRAM is always allocated
for all BL images.
The access to the on-chip SRAM is necessary for loading images from
a USB memory device (i.e. when updating firmware), so unneeded for
the usual boot procedure.
To avoid this waste, allocate the xlat region dynamically only for
BL2, and only when it is necessary.

Commit 247fc04351 ("uniphier: switch to BL2-AT-EL3 and remove BL1
support") accidentally changed the location of BL31 and BL32. The
new memory map overlaps with the audio DSP images, also gives impact
to OP-TEE. They are both out of control of ARM Trusted Firmware, so
not easy to change. This commit restores the image layout that was
originally used prior to the BL2-AT-EL3 migration.
