Introduce a new fragment configuration in u-boot to enable support for
the snagfactory tool [1], used for factory flashing of boards. Snagfactory
tool first recovers the board via USB DFU (peripheral boot), and then
uses fastboot to flash given binaries/images to MMC or other on-board
memory via USB. The fragment config can be used to generate boot binaries
for board recovery. This fragment config needs to be added additionally,
while building a53 images for USB DFU boot.
The fragment config enables configurations to allow flashing via
fastboot, manage MMC partitions and boot partitions, customize buffer
size and memory usage for fastboot and also integrate OEM commands and
UUU compatibility. It sets CONFIG_BOOTCOMMAND to start fastboot mode
immediately on startup. It also sets BOOTDELAY to 0 to reduce snagfactory
recovery time. Since BOOTCOMMAND and BOOTDELAY configs are being
modified, these changes cannot be placed in existing DFU fragment config.
Snagfactory used mtd support for flashing both SPI NAND and SPI NOR
devices. The fragment config enables mtd in u-boot and also allows SPI
flash to be treated as an MTD device.

Every SetVariable() call triggers efi_var_mem_ins() followed by
efi_var_to_storage(), even when the variable value is not actually
changing. This is unfriendly to flash-backed stores that suffer
wear from unnecessary erase/write cycles.
Add a change-detection path to efi_var_mem_ins(): when size2 == 0
(i.e. not an append) and the caller passes a non-NULL changep flag,
look up the existing variable and compare attributes, length, time
and data byte-by-byte. If everything matches, set *changep = false
and return EFI_SUCCESS without touching the variable buffer.
Both efi_set_variable_int() and efi_set_variable_runtime() now
check the flag and skip efi_var_mem_del() / efi_var_to_storage()
when nothing changed.
Introduce efi_memcmp_runtime() - a runtime-safe byte-by-byte memory
comparison helper, following the same pattern as the existing
efi_memcpy_runtime(). The standard memcmp() is not available after
ExitBootServices() and calling it from Linux will crash.

Rockchip RK356x supports up to 8 GiB DRAM, however U-Boot only includes
the initial 32-bit 0-4 GiB addressable range in its memory map,
something that matches gd->ram_top and current expected memory available
for use in U-Boot.
The vendor DRAM init blobs add following ddr_mem rk atags [1]:
4 GiB: [0x0, 0xf0000000) and [0x1f0000000, 0x200000000)
8 GiB: [0x0, 0x200000000)
Add the remaining 64-bit 4-8 GiB addressable range, that already is
reported to OS, to the U-Boot memory map to more correctly describe all
available and addressable DRAM of RK356x. While at it also add the
missing UL suffix to the PCIe address range for consistency.

This series updates the Resource Management (RM) configuration files
for AM62 family devices to align with the TIFS v11.02.09 firmware.
Background
----------
With the latest TIFS firmware (v11.02.09), an additional virtual
interrupt and event is reserved for MCU cores to DM usage on am62x,
am62ax, and am62px devices. This series brings the rm-cfg and
tifs-rm-cfg files in sync with these firmware changes across both
TI reference boards and vendor boards.
These changes are backward compatible with older TIFS firmware versions.
Additionally, the am62x platform was originally introduced without a
tifs-rm-cfg.yaml file, unlike other platforms in the AM62 family.
This series addresses that gap and enables tifs-rm-cfg in binman for
am625-sk and am62p-sk platforms.
Changes
-------
TI reference boards (patches 1-4):
- Update rm-cfg.yaml for am62x, am62ax, am62px
- Sync am62px tifs-rm-cfg.yaml with TIFS firmware template
- Add missing tifs-rm-cfg.yaml for am62x
- Enable tifs-rm-cfg in binman for am625-sk and am62p-sk
Vendor boards (patches 5-9):
- beagleplay (am62x-based)
- phytec phycore_am62x
- toradex verdin-am62
- phytec phycore_am62ax
- toradex verdin-am62p
with the required interrupt reservation. The tifs-rm-cfg.yaml files
cannot be updated without access to the corresponding SysConfig files,
as both rm-cfg.yaml and tifs-rm-cfg.yaml must remain in sync.
