The provided bootlog shows that the RedBoot partition parser was

since the comment in the device-tree says it should be at 0xfe0000.

The PMGR block in Apple Silicon SoCs is responsible for SoC power
management. There are two PMGRs in T8103, with different register
layouts but compatible registers. In order to support this as well
as future SoC generations with backwards-compatible registers, we
declare these blocks as syscons and bind to individual registers
in child nodes. Each register controls one SoC device.
The respective apple compatibles are defined in case device-specific
quirks are necessary in the future, but currently these nodes are
expected to be bound by the generic syscon driver.

This syscon child node represents a single SoC device controlled by the
PMGR block. This layout allows us to declare all device power state
controls (power/clock gating and reset) in the device tree, including
dependencies, instead of hardcoding it into the driver. The register
layout is uniform.
Each pmgr-pwrstate node provides genpd and reset features, to be
consumed by downstream device nodes.
Future SoCs are expected to use backwards compatible registers, and the
"apple,pmgr-pwrstate" represents any such interfaces (possibly with
additional features gated by the more specific compatible), allowing
them to be bound without driver updates. If a backwards incompatible
change is introduced in future SoCs, it will require a new compatible,
such as "apple,pmgr-pwrstate-v2".

When in ANALOG state, no pull-up can be applied in the GPIO HW controller,
still the setting is done into the register. The pull-up is effective
currently, only when the GPIO IRQ is requested. The correct setting is to
use directly the GPIO, instead of ANALOG state.

arm64: dts: renesas: Fix operating point table node names
Align the node names of device nodes representing operating point v2
tables with the expectations of the DT bindings in
Documentation/devicetree/bindings/opp/opp-v2.yaml.
Rename the below RZ/G2L clocks to match with the clock names used in
R-Car Gen2 and later generations.
imclk->core
clk_hs->clkh
imclk2->cd
This changes will avoid using fallback for RZ/G2L high speed clock,
if "clkh" is not used in device tree and also the code changes in
driver related to this clocks.

In practice, this power staggering approach will be included in the
bootloader (not in the kernel), as we might want to boot from a SATA
drive.
>From my experiments, if the bootloader doesn't implement the power
staggering, only one HDD will get recognized (probably cause the others
didn't boot due to few power).
Still, it makes sense to expose this block in the device-tree, so the
kernel can ensure both rails are on (and this can be shared with
u-boot).

proc/vmcore: fix clearing user buffer by properly using clear_user()
To clear a user buffer we cannot simply use memset, we have to use
clear_user(). With a virtio-mem device that registers a vmcore_cb and
has some logically unplugged memory inside an added Linux memory block,
I can easily trigger a BUG by copying the vmcore via "cp":
Some x86-64 CPUs have a CPU feature called "Supervisor Mode Access
Prevention (SMAP)", which is used to detect wrong access from the kernel
to user buffers like this: SMAP triggers a permissions violation on
wrong access. In the x86-64 variant of clear_user(), SMAP is properly
handled via clac()+stac().
To fix, properly use clear_user() when we're dealing with a user buffer.
