The format of RF parameter is changed; it doesn't encode delay parameters
into table, but the delay coding becomes regular pair of register address
and value.
To help firmware to recover RF register settings, we need to download
these parameters to firmware. For v1 format, only download partial
parameters (ignore them with addr < 0x100).

Building iwlmei without CONFIG_CFG80211 causes a link-time warning:
ld.lld: error: undefined symbol: ieee80211_hdrlen
>>> referenced by net.c
>>> net/wireless/intel/iwlwifi/mei/net.o:(iwl_mei_tx_copy_to_csme) in archive drivers/built-in.a
Add an explicit dependency to avoid this. In theory it should not
be needed here, but it also seems pointless to allow IWLMEI

The powernow-k8 driver will do checks at startup that the current
active driver is acpi-cpufreq and show a warning when they're not
expected.
Because of this the following warning comes up on systems that
support amd-pstate and compiled in both drivers:
`WTF driver: amd-pstate`
The systems that support powernow-k8 will not support amd-pstate,
so re-order the checks to validate the CPU model number first to
avoid this warning being displayed on modern SOCs.

Clevo NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2 have both a working
native and video interface. However the default detection mechanism first
registers the video interface before unregistering it again and switching
to the native interface during boot. This results in a dangling SBIOS
request for backlight change for some reason, causing the backlight to
switch to ~2% once per boot on the first power cord connect or disconnect
event. Setting the native interface explicitly circumvents this buggy
behaviour by avoiding the unregistering process.

This code works but it has a static checker warning:
drivers/net/ethernet/stmicro/stmmac/stmmac_main.c:1687 init_dma_rx_desc_rings()
warn: always true condition '(queue >= 0) => (0-u32max >= 0)'
Obviously, it makes no sense to check if an unsigned int is >= 0. What
prevents this code from being a forever loop is that later there is a
separate check for if (queue == 0).
The "queue" variable is less than MTL_MAX_RX_QUEUES (8) so it can easily
fit in an int type. Any larger value for "queue" would lead to an array
overflow when we assign "rx_q = &priv->rx_queue[queue]".

It is possible to build MMU-less kernels for Cortex-M base
microcrontrollers as well as a couple of older platforms that
have not been converted to CONFIG_ARCH_MULTIPLATFORM,
specifically ep93xx, footbridge, dove, sa1100 and s3c24xx.
It seems unlikely that anybody has tested those configurations
in recent years, as even building them is frequently broken.
A patch I submitted caused another build time regression
in this configuration. I sent a patch for that, but it seems
better to also remove the option entirely, leaving ARMv7-M
as the only supported Arm NOMMU target for simplicity.
A couple of platforms have dependencies on CONFIG_MMU, those
can all be removed now. Notably, mach-integrator tries to
support MMU-less CPU cores, but those have not actually been
selectable for a long time.
This addresses several build failures in randconfig builds that
have accumulated over the years.
