4a69c8b7fe ARM: omap1: add Kconfig dependencies for unused boards
Legacy board files with no known users are planned to get removed in
early 2023, and this covers the majority of the omap1 boards as well.

According to Tony, the actual users are all on OSK, Nokia770, and
AMS-Delta. Additionally, the sx1 and palmte boards are supported by qemu,
which is convenient for testing, so all five stay around past the initial
board removal.

As omap1 is now part of the multiplatform build and uses the common-clk
framework, it has become easier to convert these to use devicetree
based booting in the future.

3362913046 ARM: sa1100: mark most boards as unused
Most Arm board files are unused and will be removed in early
2023 if no remaining users show up. For the sa1100 platform,
the machines that are still in use are:

 - Russell's Assabet development board
 - Linus' H3600 iPaq PocketPC
 - Collie as the only qemu-supported board, to allow
   testing by others

All remaining sa1100 boards are marked to depend on
CONFIG_UNUSED_BOARD_FILES to give potential users a
last chance to speak up.

bdd50bf19b ARM: footbridge: mark cats board for removal
There are three remaining footbridge boards, as the CO285 and the HP
personal server got removed already over the years.

Russell still uses his ebsa285, while both Linus and Marc have a NetWinder
that they use for testing. Nobody so far replied that they are using cats,
so it goes on the long list of machines to be removed in early 2023 if
it stays like this.

60e3eabca4 ARM: mmp: mark all board files for removal
The mmp platform supports both ATAGS based board files and DT
booting, but it appears that nobody has been interested in

Mark all of them for removal in early 2023 with a dependency
on CONFIG_UNUSED_BOARD_FILES, leaving only the DT support
for the future, unless someone pops up who uses them.

6eea15887f ARM: ep93xx: mark most board files as unused
Most of the remaining ARM board files in the kernel have no known users,
and we plan to remove those in early 2023.

For ep93xx, Alexander Sverdlin still has access to the edb93xx family
of reference boards, while Nikita Shubin has a ts7250 and is working on
a device tree conversion for those. Hartley Sweeten has a
MACH_VISION_EP9307 that is still in use.

This is a total of nine machine definitions that we will keep
around, but these are all similar machines and are defined in only
two board files. The other six board files now have a dependency on
CONFIG_UNUSED_BOARD_FILES to indicate that they are likely going away.

3c1ca64f52 ARM: davinci: mark all ATAGS board files as unused
From an earlier discussion, it appears that the davinci da8xx machines
that are still functional have already been converted to DT, while the
remaining board files are only kept because nobody has stepped up to
remove them.

Mark all these boards as 'depends on UNUSED_BOARD_FILES' with the
plan to remove them in early 2023 after the next longterm supported
kernel is out.

0c00a537bc ARM: orion: add ATAGS dependencies
Most of the remaining arm board files in the kernel are unused and will be
removed in early 2023 if no users step up.  So far I got no user replies
about the orion5x and mv78xx0 machines, but these are still supported
in the default kernel of the Debian 'armel' (armv5 softfloat) distro,
and there is an active project on github that tries to keep some of
these machines working, and Mauri Sandberg is working on a DT conversion
for the D-Link DNS-323.

It appears the Debian-on-Buffalo project has not got the Terastation WXL
working in a few years, and the other mv78xx0 machines are just the
reference designs, so I assume none of these have remaining users.

For the Orion5x family, the same is probably true for its reference
implementations (RD88Fxxxxx, DB88F281) and the machines with less than
64MB of memory (WNR854T, WRT350N v2).

The remaining nine machines are now scheduled to be kept for at least
2023, hopefully to be replaced with DT based versions.

The mv78xx0_defconfig file needs to enable CONFIG_UNUSED_BOARD_FILES
to still build, while the other affected defconfig files lose the
specific boards.

b5aaaa666a ARM: pxa: add Kconfig dependencies for ATAGS based boards
Most of the traditional board files are no longer used by anyone and
will be removed next year, while the DT based machine support remains.

Adding a CONFIG_ATAGS dependency around all the board files means
that they now actaully get disabled when ATAGS support is left out,
and the individual boards that have no known users are marked
as depending on CONFIG_UNUSED_BOARD_FILES, with the plan to remove
them in early 2023 unless someone else shows interest.

Laurence de Bruxelles intends to work on converting the Spitz/Akita/Borzoi
family of Sharp Zaurus SL machines to DT, to make that easier those
remain for the moment.

In addition, the "Gumstix" machine is the one that is supported in
qemu with 256MB of RAM, which makes it particularly nice for testing,
I'm leaving it in hoping that someone can take care of converting it to
DT as well.

Finally, Marc Zyngier is still able to test the Zeus and Viper machines,
so these could be saved as well if anyone wants to conver them to DT.
This seems less likely, so I'm marking them as unused for the time being.

For the defconfig files, both the pxa3xx_defconfig and pxa_defconfig
now only enable the boards that are not marked as unused, while all the
other ones explicitly enable CONFIG_UNUSED_BOARD_FILES to still allow
building the kernels.

77f349b770 ARM: defconfig: kill remnants of CONFIG_LEDS
CONFIG_LEDS was replaced by CONFIG_NEW_LEDS over ten years ago with commit
fa8bbb13ab49 ("ARM: use new LEDS CPU trigger stub to replace old one"),
but some defconfig files still reference it.

Replace it and its sub-options with the corresponding new versions.

Some of these machines may not actually have a new-style LED driver,
and I did not check them individually as most of the machines are
going away soon anyway.

ddd366bf01 ARM: defconfig: address renamed CONFIG_DEBUG_INFO=y
CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.

This was actually not what I had in mind when I suggested making
it a 'choice' statement, but it's too late to change again now,
and the Kconfig logic is more sensible in the new form.

Change any defconfig file that had CONFIG_DEBUG_INFO enabled
but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain
default.

2002f39687 ARM: refresh defconfig files
A lot of Kconfig options have changed over the years, and we tend
to not do a blind 'make defconfig' to refresh the files, to ensure
we catch options that should not have gone away.

I used some a bit of scripting to only rework the bits where an
option moved around in any of the defconfig files, without also
dropping any of the other lines, to make it clearer which options
we no longer have.

0f5b2c69a4 efi: vars: Remove deprecated 'efivars' sysfs interface
Commit 5d9db883761a ("efi: Add support for a UEFI variable filesystem")
dated Oct 5, 2012, introduced a new efivarfs pseudo-filesystem to
replace the efivars sysfs interface that was used up to that point to
expose EFI variables to user space.

The main problem with the sysfs interface was that it only supported up
to 1024 bytes of payload per file, whereas the underlying variables
themselves are only bounded by a platform specific per-variable and
global limit that is typically much higher than 1024 bytes.

The deprecated sysfs interface is only enabled on x86 and Itanium, other
EFI enabled architectures only support the efivarfs pseudo-filesystem.

So let's finally rip off the band aid, and drop the old interface
entirely. This will make it easier to refactor and clean up the
underlying infrastructure that is shared between efivars, efivarfs and
efi-pstore, and is long overdue for a makeover.

96479c0980 ARM: multiplatform changes, part 2
The second part of the multiplatform changes now converts the
 Intel/Marvell PXA platform along with the rest. The patches went through
 several rebases before the merge window as bugs were found, so they
 remained separate.
 
 This has to touch a lot of drivers, in particular the touchscreen,
 pcmcia, sound and clk bits, to detach the driver files from the
 platform and board specific header files.

Patch series from Nick Hawkins:

"The GXP is the HPE BMC SoC that is used in the majority of HPE current
 generation servers. Traditionally the asic will last multiple
 generations of server before being replaced.

 Info about SoC:

  HPE GXP is the name of the HPE Soc. This SoC is used to implement many
  BMC features at HPE. It supports ARMv7 architecture based on the Cortex
  A9 core. It is capable of using an AXI bus to which a memory controller
  is attached. It has multiple SPI interfaces to connect boot flash and
  BIOS flash. It uses a 10/100/1000 MAC for network connectivity. It has
  multiple i2c engines to drive connectivity with a host infrastructure.
  The initial patches enable the watchdog and timer enabling the host to
  be able to boot."

ecf0aa5317 ARM: ARMv4T/v5 multiplatform support for v5.19, part 1
This series has been 12 years in the making, it mostly finishes the
 work that was started with the founding of Linaro to clean up platform
 support in the kernel.
 
 The largest change here is a cleanup of the omap1 platform, which
 is the final ARM machine type to get converted to the common-clk
 subsystem. All the omap1 specific drivers are now made independent of the
 mach/*.h headers to allow the platform to be part of a generic ARMv4/v5
 multiplatform kernel. The last bit that enables this support is still
 missing here while we wait for some last dependencies to make it into
 the mainline kernel through other subsystems.
 
 The s3c24xx, ixp4xx, iop32x, ep93xx and dove platforms were all almost
 at the point of allowing multiplatform kernels, this work gets completed
 here along with a few additional cleanup.  At the same time, the s3c24xx
 and s3c64xx are now deprecated and expected to get removed in the future.
 
 The PXA and OMAP1 bits are in a separate branch because of dependencies.
 Once both branches are merged, only the three Intel StrongARM platforms
 (RiscPC, Footbridge/NetWinder and StrongARM1100) need separate kernels,
 and there are no plans to include these.

ARM: configs: Enable audio on BeagleBone Black in multi_v7_defconfig
The BeagleBone Black supports audio over HDMI, using a combination of the
DaVinci McASP (used for audio by a very large proportion of DaVinci systems
with audio support) and a TDA998x device driving the HDMI link (this is a
very widely used driver). Build both drivers as modules in multi_v7_defconfig
so they can be more easily included in testing.

386d0503c1 ARM: configs: at91: Enable AUTOFS_FS required by systemd
Align all at91 defconfigs to required options for systemd.
The missing of autofs would cause warnings on boot
when not available.

44a26be079 ARM: configs: at91: Enable options required for systemd
Even smaller embedded systems are using systemd these days, as
are test automation systems like KernelCI, so it is useful to be
able to use systemd on these boards by default. Enable options
that are missing in the at91_dt_defconfig, cgroups which is
critical and autofs4 which is less critical but causes warnings
on boot when not available.

5c6f84728d ARM: configs: at91: Remove MTD_BLOCK and use MTD_UBI_BLOCK for read only block FS
Using mtdblock on raw flashes is generally a bad idea as it lacks
wear-leveling, bad block handling or power-cut management.
What happens when you use mtdblock and you change any sector of your
mtdblockX device, is that it reads the whole corresponding eraseblock into
the memory, erases the eraseblock, changes the sector in RAM, and writes
the whole eraseblock back. If you have a power failure when the eraseblock
is being erased, you lose all the block device sectors in it. The flash
will likely decay soon because the eraseblocks will wear out.

Remove this archaic tool as its use case should rather be only for debug
purposes. This means that write-capable block file systems like ext2,
ext3, FAT, etc. will no longer be addressed with at91 defconfigs. For
read only block filesystems like SquashFS, use MTD_UBI_BLOCK instead and
benefit of UBI's bit-flip handling and wear-levelling.
