As discussed at [1], the Amlogic Meson GX SoCs can embed a BL31 firmware
and a secondary BL32 firmware.
Since mid-2017, the reserved memory address of the BL31 firmware was moved
and grown for security reasons.
But mainline U-Boot and Linux has the old address and size fixed.
These SoCs have a register interface to get the two firmware reserved
memory start and sizes.
This patch adds a dynamic reservation of the memory zones in the device tree bootmem
reserved memory zone used by the kernel in early boot.
To be complete, the memory zones are also added to the EFI reserved zones.
Depends on patchset "Add support for Amlogic GXL Based SBCs" at [2].

Rockchip bootrom will enter download mode if it returns from

in the backup partition.
This patch provide a method to instruct the system to back to
bootrom download mode by checking the BROM_DOWNLOAD_FLAG register.
As the bootrom download function relys on some modules such as
interrupts, so we need to back to bootrom as early as possbile
before the tpl/spl code override the interrupt configurations.

The back-to-bootrom implementation for Rockchip has always relied on
the stack-pointer being valid on entry, so there was little reason to
have this as an assembly implementation.
This provides a new C-only implementation of save_boot_params and
back_to_bootrom (relying on setjmp/longjmp) and removes the older
assembly-only implementation.

The previous setjmp-implementation (as a static inline function that
contained an 'asm volatile' sequence) was extremely fragile: (some
versions of) GCC optimised the set of registers. One critical example
was the removal of 'r9' from the clobber list, if -ffixed-reg9 was
supplied.
To increase robustness and ensure PCS-compliant behaviour, the setjmp
and longjmp implementation are now in assembly and closely match what
one would expect to find in a libc implementation.

Some Rockchip BROM versions (e.g. the RK3188 and RK3066) first read 1KB data
from NAND into SRAM and executes it. Then, following a return to bootrom, the
BROM loads additional code to SRAM (not overwriting the first block read) and
reenters at the same address as the first time.
To support booting either a TPL (on the RK3066) or SPL (on the RK3188) using
this model of having to count entries, this commit adds code to the boot0
hook to track the number of entries and handle them accordingly.

The boot0 hook on ARM does not insert its payload before the vector
table. This is both a mismatch with thec comment above it and
contradict usage of the boot0 hook on ARM64.
To fix this (and unify the semantics for ARM and ARM64), we change the
boot0-hook semantics on ARM to match those on ARM64:
(1) if a boot0-hook is present it is inserted at the start of
the image
(2) if a boot0-hook is present, emitting the ARM vector table
(and the _start) symbol are suppressed in vectors.S and
the boot0-hook has full control over where and when it
wants to emit these
