In order to unzipped kernel from androidboot img, extra memory for
loadaddr is needed. So once fastboot is enabled fastboot memory also
share with loadaddr.
That can balance with memory constrain soc and android usecase.

Some androidboot image have invalid kernel/ramdisk load addr,
force to ignore those value and use loadaddr instead.
There is a concern on exposing the whole memory to image loading is
dangerous. Also, since it's not always possible to change the load
addr by repacking the boot.img (mainly due to AVB signature mismatch),
we need a way to use kernel_addr_r and ramdisk_addr_r.

The default DIP switch configuration on RB1/2 is to enable flashing
support via USB type-c port either using QDL or fastboot. It's just
cumbersome to get the host mode working in U-Boot via DIP switch toggle
when you need the flashing capability using the type-c port.
So instead lets enable fastboot in U-Boot for RB1/2 boards which is
more useful in the default board DIP switch configuration. This let's

The H-A133L board is an industrial development board made by Liontron.
It contains a number of dedicated JST connectors, to connect external
peripherals. It features:
- Allwinner A133 SoC (4 * Arm Cortex-A53 cores at up to 1.6 GHz)
- 1 GiB, 2 GiB or 4 GiB of LPDDR4 DRAM
- between 16 and 128 GiB eMMC flash
- AXP707 PMIC (compatible to AXP803)
- 100 Mbit/s RJ45 Ethernet socket, using an JLSemi JL1101 PHY
- XR829 WIFI+Bluetooth chip
- 2 * USB 2.0 USB-A ports, plus three sets of USB pins on connectors
(connected via a USB hub connected to USB1 on the SoC)
- microSD card slot
- 3.5mm A/V port
- 12V power supply
- connectors for an LVDS or MIPI-DSI panel
Add the devicetree describing the board's peripherals and their
connections.
Despite being a devboard, the manufacturer does not publish a schematic
(I asked), so the PMIC rail assignments were bases on BSP dumps,
educated guesses and some experimentation. Dropping the always-on
property from any of the rails carrying it will make the board hang as
soon as the kernel turns off unused regulators.

The Allwinner A100 SoC has been around for a while, mostly on cheap
tablets, but didn't generate much interest in the community so far.
There were some efforts by two Allwinner employees in 2020, which led
to basic upstream Linux support for that SoC, although this momentum
dried up pretty quickly, leaving a lot of peripherals unsupported.
The A100 was silently replaced with the seemingly identical Allwinner
A133, which is reportedly a better bin of the A100. So far we assume
that both are compatible from a software perspective. There are some
more devices with the A133 out there now, so people are working on
filling the gaps, and adding U-Boot (and TF-A) support.
Based on the just added pinctrl, clock and DRAM support, this adds the
missing bits, mostly addresses and values for the SPL.
The A133 seems to be an predecessor to the H6, so we can share a lot of
code with that (and the H616 code), and just need to adjust some details.

Commit 6fe50e395080 ("arm: asm/system.h: mrc and mcr need .arm if
__thumb2__ is not set") is not a proper fix for the LTO link error
mentioned in its description. It causes 32-bit arm instructions to be
mixed with thumb instructions, which the Kirkwood SoCs do not support.
For example, board_init_r() is mostly generated in Thumb-1 mode as
expected since the build flags contain -mthumb -mthumb-interwork. The
MCR instruction corresponding to writefr_extra_feature_reg() is also
correcly emitted as a 32-bit ARM instruction (it cannot be encoded in
Thumb-1 anyways). The problem is, the compiler inlines the MCR without
generating the BX or BLX instruction which are needed to transition
between the ARM and the Thumb-1 states. From the objdump output:
006186a0 <board_init_r>:
board_init_r():
/home/jerome/work/u-boot/common/board_r.c:799

^^^^^^^^
32-bit ARM instruction
Further investigation is needed to understand how to fix the issue so
that the code size is minimal for all boards. In the mean time, this
fix disables LTO for the two problematic files (common/board_f.c and
common/board_r.c). This makes the Kirkwood-based boards bootable again.
The binary size is increased by 1048 bytes which is perfectly
acceptable.

This patch enhances the Qualcomm watchdog driver by introducing
support for dynamic timeout configuration. Specifically:
- Calculates and sets the bark and bite timeout values based on
the clock rate and the requested timeout in milliseconds.
- Adds retrieval of the watchdog clock rate during probe using
the common clock framework.
- Adds a default timeout value for ARCH_SNAPDRAGON
in WATCHDOG_TIMEOUT_MSECS.
These changes improve the configurability and accuracy of the
watchdog timer on Qualcomm platforms.

As stated in 5e847f7729b3 ("efi_loader: call efi_init_early() earlier"):
efi_init_early() creates an event hook for block device probing.
It has to be called before any block device is probed.
Indeed, efi_bl_init() registers EVT_DM_POST_PROBE event, which calls
efi_disk_probe() whenever any block device is probed. And to make that
hook work, the initialization of all block devices was put after
efi_init_early() in initcall_run_r():
INITCALL(efi_init_early);
INITCALL(initr_nand);
INITCALL(initr_onenand);
INITCALL(initr_mmc);
Because LDFW firmware is being read from MMC, attempt to load LDFW in
board_init() causes MMC driver to be probed. And because board_init() is
executed before efi_init_early(), the hook mentioned above won't work
for MMC devices anymore. So EFI disk objects won't be created, which in
turn makes the EFI subsystem non-functional, showing next symptoms:
- 'efidebug dh' output is empty
- attempt to add boot devices in 'eficonfig' shows this message:
"No block device found!"
- 'bootefi selftest $fdtcontroladdr' shows this warning:
"Cannot persist EFI variables without system partition"
- booting GRUB with 'bootefi' runs minimal GRUB shell which doesn't
see any block devices as well, probably because EFI vars weren't
passed
Load LDFW in board_late_init() instead, as it's called after
efi_init_early(). This fixes the described problem and makes it possible
to run EFI apps like GRUB correctly, add entries in 'eficonfig', and
makes 'efivar --list' command in Linux rootfs actually show EFI
variables.
The only user of LDFW at the moment is the TRNG driver, and it's probed
later, only when it's going to be used (e.g. on "rng" command). So it's
fine to load LDFW in board_late_init(). Now the corresponding call order
will look like this:
efi_init_early()
initr_mmc()
mmc_probe()
EVT_DM_POST_PROBE -> efi_disk_probe()
board_late_init()
load_ldfw() -> fs_read(), blk_dread()
exynos_trng_probe()
