BL31 is running out of space, and the use-case of SPM doesn't require it
to be in SRAM. To prevent BL31 from running out of space in the future,
move BL31 to DRAM if SPM is enabled.

Secure Partition Manager design document updated to reflect the changes.

Increased the size of the stack of BL31 for builds with SPM.

The translation tables used by SPM in Arm platforms have been moved back
to the 'xlat_tables' region instead of 'arm_el3_tzc_dram'. Everything is
in DRAM now, so it doesn't make sense to treat them in a different way.

Simplify the code of the SMC handler by extracting the code of

Instead of just knowing if the Secure Partition is being initialized or
not, this generic state enum can be used to tell if the Secure Partition
is busy and to add more states in the future if needed.

Also, the spinlock of the secure_partition_context_t structure now only
protects against concurrent accesses to the state of the secure
partition. Previously, it used to lock down the whole structure, thus
preventing one CPU to access any of its fields while another CPU was
executing the partition.

The current internal names are too long, which makes it hard to write

Move all information related to a Secure Partition to the struct
secure_partition_context_t.

This requires an in-depth refactor because most of the previous code of
SPM relied on global information.

This function can be currently accessed through the wrappers
cm_init_context_by_index() and cm_init_my_context(). However, they only
work on contexts that are associated to a CPU.

By making this function public, it is possible to set up a context that
isn't associated to any CPU. For consistency, it has been renamed to
cm_setup_context().

Ensure read and write of flags defined in the console struct are 32 bit

From TF-A v1.5, FVP supports loading the kernel FDT through
firmware as part of dynamic configuration feature. This means
that the FDT no longer needs to be loaded via Model parameters.
This patch updates the user guide to reflect the same.

Since FVP enables dynamic configuration by default, the DT blobs are
compiled from source and included in FIP during build. Hence this
patch removes the dtb files from the `fdts` folder.

Xilinx platform mangement related changes

In 'console_set_scope' and when registering a console, field 'flags' of
'console_t' is assigned a 32-bit value. However, when it is actually
used, the functions perform 64-bit reads to access its value. This patch
changes all 64-bit reads to 32-bit reads.

Existing code blocks each IPI send request in ipi_mb_notify()
function till pmu clears respective bit in ipi observation
register.

After sending PM_SYSTEM_SHUTDOWN request to PMU, PMU will
restart APU. While PMU is restarting APU, ATF is running out
of OCM, which can cause read/write hang from/to OCM.
There is no need to wait for notification from PMU in case
of SystemShutdown request in ATF, as APU is going to restart.

This patch fixes APU only restart issue.

Xilinx now requires the PMU FW when using ATF, so it doesn't make sense
to maintain checks for the PMU FW in ATF. This also means that cases
where ATF came up before the PMU FW (such as on QEMU) ATF will now hang
