When build U-boot with clang with using commands:
$ make HOSTCC=clang xenguest_arm64_defconfig
$ make HOSTCC=clang CROSS_COMPILE=aarch64-linux-gnu- \
CC="clang -target aarch64-linux-gnueabi" -j8
The compiler reports error:
/tmp/start-acdf31.s:330:1: error: symbol '_start' is already defined
_start:
^
Because the symbol '_start' has been defined twice, one is defined in
arch/arm/cpu/armv8/start.S, another is defined in the header
boot0-linux-kernel-header.h.
To fix building failure, this patch removes the symbol '_start' from
boot0-linux-kernel-header.h.

ARM requires a 4-byte alignment on all ARM code (though this
requirement is relaxed to 2-byte for some THUMB code) and we
should be explicit about that here.
GAS has its own fix for this[1] that forces proper alignment
on any section containing assembled instructions, but this is
not universal: Clang's and other gaslike assemblers lack this
implicit alignment. Whether or not this is considered a bug in
those assemblers, it is better to ask directly for what we want.

Booting from sdmmc on RK3588 currently works because of a workaround in
the device tree, clocks are reordered so that the driver use ciu-sample
instead of ciu, and the BootRom initializes sdmmc clocks before SPL is
loaded into DRAM.
The sdmmc clocks are normally controlled by TF-A using SCMI. However,
there is a need to control these clocks in SPL, before TF-A has started.
This adds a rk3588_scru driver to control the sdmmc clocks in SPL before
TF-A has started, using scru regs. It also adds a small glue driver to
bind the scmi clock node to the rk3588_scru driver in SPL.

Some SoCs of the H616 family use a die variant, that puts some CPU power
and reset control registers at a different address. There are examples
of two instances of the same board, using different die revisions of the
otherwise same H313 SoC. We need to write to a register in that block
*very* early in the SPL boot, to switch the core to AArch64.
Since the devices are otherwise indistinguishable, let the SPL code read
that die variant and use the respective RVBAR address based on that.
That is a bit tricky, since we need to do that in hand-coded AArch32
machine language, shared by all 64-bit SoCs. To avoid build dependencies
in this mess, we always provide two addresses to choose from, and just
give identical values for all other SoCs. This allows the same code to
run on all 64-bit SoCs, and controls this switch behaviour purely from
Kconfig.

To switch the ARMv8 Allwinner SoCs into the 64-bit AArch64 ISA, we need
to program the 64-bit start code address into an MMIO mapped register
that shadows the architectural RVBAR register.
This address is SoC specific, with just two versions out there so far.
Now a third address emerged, on a *variant* of an existing SoC (H616).
Change the boot0.h start code to make this address a Kconfig
selectable option, to allow easier maintenance.

On popular request make the display driver from T20 work on T30 as
well. Turned out to be quite straight forward. However a few notes
about some things encountered during porting: Of course the T30 device
tree was completely missing host1x as well as PWM support but it turns
out this can simply be copied from T20. The only trouble compiling the
Tegra video driver for T30 had to do with some hard-coded PWM pin
muxing for T20 which is quite ugly anyway. On T30 this gets handled by
a board specific complete pin muxing table. The older Chromium U-Boot
2011.06 which to my knowledge was the only prior attempt at enabling a
display driver for T30 for whatever reason got some clocking stuff
mixed up. Turns out at least for a single display controller T20 and
T30 can be clocked quite similar. Enjoy.

The handshake is needed when M33 is booted or DBD_EN fused, because both
