commit 260364d112bc822005224667c0c9b1b17a53eafd upstream.
The semantics of pfn_valid() is to check presence of the memory map for a
PFN and not whether a PFN is covered by the linear map. The memory map
may be present for NOMAP memory regions, but they won't be mapped in the
linear mapping. Accessing such regions via __va() when they are
memremap()'ed will cause a crash.
On v5.4.y the crash happens on qemu-arm with UEFI [1]:

On kernels v5.10.y and newer the same crash won't reproduce on ARM because
commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with
for_each_mem_range()") changed the way memory regions are registered in
the resource tree, but that merely covers up the problem.
On ARM64 memory resources registered in yet another way and there the
issue of wrong usage of pfn_valid() to ensure availability of the linear
map is also covered.
Implement arch_memremap_can_ram_remap() on ARM and ARM64 to prevent access
to NOMAP regions via the linear mapping in memremap().

Flexcom3 is used as board console serial. There are no pull-ups on these
lines on the board. This means that if a cable is not connected (that has
pull-ups included), stray characters could appear on the console as the
floating pins voltage levels are interpreted as incoming characters.
To avoid this problem, enable the internal pull-ups on these lines.

The pinout of the OMAP35 and DM37 variants of the SOM-LV are the
same, but the macros which define the pinmuxing are different
between OMAP3530 and DM3730. The pinmuxing was correct for
for the DM3730, but wrong for the OMAP3530. Since the boot loader
was correctly pin-muxing the pins, this was not obvious. As the
bootloader not guaranteed to pinmux all the pins any more, this
causes an issue, so the pinmux needs to be moved from a common
file to their respective board files.

which does a write to the CQSPI_REG_WR_COMPLETION_CTRL register

Intel's SoCFPGA platforms does not implement the

results in a crash!

Commit 06b93644f4d1 ("media: Kconfig: add an option to filter in/out
platform drivers") introduced CONFIG_MEDIA_PLATFORM_SUPPORT, to allow
more fine grained control over the inclusion of certain Kconfig files.
multi_v5_defconfig was selecting some drivers described in
drivers/media/platform/Kconfig, which now wasn't included anymore.
Explicitly set the new symbol in multi_v5_defconfig to bring those
drivers back.
This enables some new V4L2 and VIDEOBUF2 features, but as modules only.

While the HVS has the same context memory size in the BCM2711 than in
the previous SoCs, the range allocated to the registers doubled and it
now takes 16k + 16k, compared to 8k + 16k before.
The KMS driver will use the whole context RAM though, eventually
resulting in a pointer dereference error when we access the higher half
of the context memory since it hasn't been mapped.
