Refine the function plat_add_sp_images_load_info() by saving the
previous node and only setting its next link when the current node is
valid. This can reduce the check for the next node and simply the
total logic.

The traverse flow in function plat_add_sp_images_load_info() will find
the last node in the main load info list, with its
next_load_info==NULL. However this node is still useful and should not
be overridden with SP node info.

The bug will cause below error on RDN2 for spmd enabled:

ERROR:   Invalid NT_FW_CONFIG DTB passed

Fix the bug by only setting the next_load_info of the last node in the
original main node list.

  stm32mp1: add TZC400 interrupt management

  tzc400: add support for interrupts

A TZC400 controller is placed inline on DRAM channels and regulates
the secure and non-secure accesses to both secure and non-secure
regions of the DRAM memory. Configure each of the TZC controllers
across the Chips.

For use by secure software, configure the first chip's trustzone
controller to protect the upper 16MB of the memory of the first DRAM
block for secure accesses only. The other regions are configured for
non-secure read write access. For all the remote chips, all the DRAM
regions are allowed for non-secure read and write access.

On a multi-chip platform, the boot CPU on the first chip programs the
TZC controllers on all the remote chips. Define a memory region map for
the TZC controllers for all the remote chips and include it in the BL2
memory map table.

In addition to this, for SPM_MM enabled multi-chip platforms, increase
the number of mmap entries and xlat table counts for EL3 execution
context as well because the shared RAM regions and GIC address space of
remote chips are accessed.

When the BL31 for the Allwinner H616 runs in DRAM, we need to make sure
we tell the non-secure world about the memory region it uses.

Add a reserved-memory node to the DT, which covers the area that BL31
could occupy. The "no-map" property will prevent OSes from mapping
the area, so there would be no speculative accesses.

The new Allwinner H616 SoC lacks the management controller and the secure
SRAM A2, so we need to tweak the memory map quite substantially:
We run BL31 in DRAM. Since the DRAM starts at 1GB, we cannot use our
compressed virtual address space (max 256MB) anymore, so we revert to
the full 32bit VA space and use a flat mapping throughout all of it.

The missing controller also means we need to always use the native PSCI
ops, using the CPUIDLE hardware, as SCPI and suspend depend on the ARISC.

In preparation for changing the memory map, express the locations of the
various code and data pieces more dynamically, allowing SoCs to override
the memmap later.
Also prepare for the SCP region to become optional.

No functional change.

The code to power the current core off when SCPI is not available is now
different for the two supported SoC families.
To make adding new platforms easier, move sunxi_cpu_power_off_self()
into the SoC directory, so we don't need to carry definitions for both
methods for all SoCs.

On the H6 we just need to trigger the CPUIDLE hardware, so can get rid
of all the code to program the ARISC, which is now only needed for the
A64 version.

For the existing SoCs we support, we use SEPARATE_NOBITS_REGION, to move
some parts of the data into separate memory regions (to save on the SRAM
A2 we are loaded into).
For the upcoming H616 platform this is of no concern (we run in DRAM),
so make this flag a platform choice instead.

The upcoming refactoring to support the new H616 SoCs will push the A64
build over the edge, by using more than the 48KB of SRAM available.

To reduce the code size, set some libfdt options that aim to reduce
sanity checks (for saving code space):
- ASSUME_LATEST: only allow v17 DTBs (as created by dtc)
- ASSUME_NO_ROLLBACK: don't prepare for failed DT additions
- ASSUME_LIBFDT_ORDER: assume sane ordering, as done by dtc
