The platform lost the framebuffer due to a commit solving a
circular dependency in v5.14-rc1, so add it back in by explicitly
selecting the framebuffer.
Also fix up some Kconfig options that got dropped or moved around
while we're at it.

The usage of usb-nop-xceiv PHY on Raspberry Pi boards with BCM283x has
been a "regression source" a lot of times. The last case is breakage of
USB mass storage boot has been commit e590474768f1 ("driver core: Set
fw_devlink=on by default") for multi_v7_defconfig. As long as
NOP_USB_XCEIV is configured as module, the dwc2 USB driver defer probing
endlessly and prevent booting from USB mass storage device. So make
the driver built-in as in bcm2835_defconfig and arm64/defconfig.

The platform lost the framebuffer due to a commit solving a
circular dependency in v5.14-rc1, so add it back in by explicitly
selecting the framebuffer.
The U8500 has also gained a few systems using touchscreens from
Cypress, Melfas and Zinitix so add these at the same time as
we're updating the defconfig anyway.

This updates the Versatile Express defconfig for the changes
in the v5.14-rc1 kernel:
- The Framebuffer CONFIG_FB needs to be explicitly selected
or we don't get any framebuffer anymore. DRM has stopped to
select FB because of circular dependency.
- CONFIG_CMA options were moved around.
- CONFIG_MODULES options were moved around.
- CONFIG_CRYPTO_HW was moved around.

As of commit f611b1e7624ccdbd ("drm: Avoid circular dependencies for
CONFIG_FB"), CONFIG_FB is no longer auto-enabled. While CONFIG_FB may
be considered unneeded for systems where graphics is provided by a DRM
driver, R-Mobile A1 still relies on a frame buffer device driver for
graphics support.
Restore support for graphics on R-Mobile A1 and graphical consoles on
DRM-based systems by explicitly enabling CONFIG_FB in the defconfig for
Renesas ARM systems.

Patch series "drivers/char: remove /dev/kmem for good".
Exploring /dev/kmem and /dev/mem in the context of memory hot(un)plug and
memory ballooning, I started questioning the existence of /dev/kmem.
Comparing it with the /proc/kcore implementation, it does not seem to be
able to deal with things like
a) Pages unmapped from the direct mapping (e.g., to be used by secretmem)
-> kern_addr_valid(). virt_addr_valid() is not sufficient.
b) Special cases like gart aperture memory that is not to be touched
-> mem_pfn_is_ram()
Unless I am missing something, it's at least broken in some cases and might
fault/crash the machine.
Looks like its existence has been questioned before in 2005 and 2010 [1],
after ~11 additional years, it might make sense to revive the discussion.
CONFIG_DEVKMEM is only enabled in a single defconfig (on purpose or by
mistake?). All distributions disable it: in Ubuntu it has been disabled
for more than 10 years, in Debian since 2.6.31, in Fedora at least
starting with FC3, in RHEL starting with RHEL4, in SUSE starting from
15sp2, and OpenSUSE has it disabled as well.
1) /dev/kmem was popular for rootkits [2] before it got disabled
basically everywhere. Ubuntu documents [3] "There is no modern user of
/dev/kmem any more beyond attackers using it to load kernel rootkits.".
RHEL documents in a BZ [5] "it served no practical purpose other than to
serve as a potential security problem or to enable binary module drivers
to access structures/functions they shouldn't be touching"
2) /proc/kcore is a decent interface to have a controlled way to read
kernel memory for debugging puposes. (will need some extensions to
deal with memory offlining/unplug, memory ballooning, and poisoned
pages, though)
3) It might be useful for corner case debugging [1]. KDB/KGDB might be a
better fit, especially, to write random memory; harder to shoot
yourself into the foot.
4) "Kernel Memory Editor" [4] hasn't seen any updates since 2000 and seems
to be incompatible with 64bit [1]. For educational purposes,
/proc/kcore might be used to monitor value updates -- or older
kernels can be used.
5) It's broken on arm64, and therefore, completely disabled there.
Looks like it's essentially unused and has been replaced by better
suited interfaces for individual tasks (/proc/kcore, KDB/KGDB). Let's
just remove it.

Pull ARM Nuvoton WPCM450 platform support from Arnd Bergmann:
"The Nuvoton WPCM450 BMC is an older chip based on the ARM926 CPU core
that remains in use on Supermicro X9 server boards among others.
Support gets added for a particular server board using this SoC along
with the basic platform bringup.
As the platform is a predecessor to the npcm7xx platform we already
support, it is added to the same directory, despite using a different
name. It also seems to be related to the older w90x900/nuc9xx platform
that was removed last year"

Pull ARM SoC driver updates from Arnd Bergmann:
"Updates for SoC specific drivers include a few subsystems that have
their own maintainers but send them through the soc tree:
TEE/OP-TEE:
- Add tracepoints around calls to secure world
Memory controller drivers:
- Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
- Add debug statistics to Tegra20 memory controller
- Update Tegra bindings and convert to dtschema
ARM SCMI Firmware:
- Support for modular SCMI protocols and vendor specific extensions
- New SCMI IIO driver
- Per-cpu DVFS
The other driver changes are all from the platform maintainers
directly and reflect the drivers that don't fit into any other
subsystem as well as treewide changes for a particular platform.
SoCFPGA:
- Various cleanups contributed by Krzysztof Kozlowski
Mediatek:
- add MT8183 support to mutex driver
- MMSYS: use per SoC array to describe the possible routing

avoid issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as
we now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and
dra7
- omap-prm driver needs to enable autoidle retention support for
omap4
- omap5 clocks are missing gpmc and ocmc clock registers
- pci-dra7xx now needs to use builtin_platform_driver instead of
using builtin_platform_driver_probe for deferred probe to work
Raspberry Pi:
- Fix-up all RPi firmware drivers so as for unbind to happen in an
orderly fashion
- Support for RPi's PoE hat PWM bus
Qualcomm

The userspace consumer is a development tool, not intended for producton

for specific machines so is not a good fit for defconfig, remove it from
those defconfigs where it is enabled. No system in mainline actually
instantiates one.
