In the case of the s805x the drivers/hwmon directory contains the
scpi_hwmon kernel module.
On a running system, lsmod would output the following dependencies:
arm_scpi 24576 2 clk_scpi,scpi_hwmon
It means that if the clock driver is bundled in the initramfs it will
bring arm_scpi. But if scpi_hwmon is missing the scpi will be incomplete
and it can lead to crashes.
When the hwmon is bundled, no crash occurs

Some SoCs now have drivers that user devfreq in early init and fail
if the drivers are missing so make sure we have them in the initrd.

Currently there is no usb support on RPi4 in the
initrd phase as the pcie-brcmstb module is missing.
If part of the boot is handled from a USB stick
(e.g. with Ignition), the stick cannot be accessed.

If hostonly mode is in use, and there isn't any block device included
as hostonly device, then the initramfs won't need any block driver.
Eg. for kdump built image, there could be only one nfs mount point,
or the initramfs may only execute some network operation then reboot.
In such case, skip block driver installation to save space and time.

For the shell scripts, new environment variables were introduced.
dracutsysrootdir is the root directory, file existence checks use it.
DRACUT_LDCONFIG can override ldconfig with a different one that works
on the sysroot with foreign binaries.
DRACUT_LDD can override ldd with a different one that works
with foreign binaries.
DRACUT_TESTBIN can override /bin/sh. A cross-compiled sysroot
may use symlinks that are valid only when running on the target
so a real file must be provided that exist in the sysroot.
DRACUT_INSTALL now supports debugging dracut-install in itself
when run by dracut but without debugging the dracut scripts.
E.g. DRACUT_INSTALL="valgrind dracut-install or
DRACUT_INSTALL="dracut-install --debug".
DRACUT_COMPRESS_BZIP2, DRACUT_COMPRESS_LBZIP2, DRACUT_COMPRESS_LZMA,
DRACUT_COMPRESS_XZ, DRACUT_COMPRESS_GZIP, DRACUT_COMPRESS_PIGZ,
DRACUT_COMPRESS_LZOP, DRACUT_COMPRESS_ZSTD, DRACUT_COMPRESS_LZ4,
DRACUT_COMPRESS_CAT: All of the compression utilities may be
overridden, to support the native binaries in non-standard places.
DRACUT_ARCH overrides "uname -m".
SYSTEMD_VERSION overrides "systemd --version".
The dracut-install utility was overhauled to support sysroot via
a new option -r and fixes for clang-analyze. It supports
cross-compiler-ldd from
https://gist.github.com/jerome-pouiller/c403786c1394f53f44a3b61214489e6f
DRACUT_INSTALL_PATH was introduced so dracut-install can work with
a different PATH. In a cross-compiled environment (e.g. Yocto), PATH
points to natively built binaries that are not in the host's /bin,
/usr/bin, etc. dracut-install still needs plain /bin and /usr/bin
that are relative to the cross-compiled sysroot.
The hashmap pool allocate_tile/deallocate_tile code was removed
because clang-analyze showed errors in it. hashmap_copy was removed
because it wasn't used and clang-analyze showed errors in it.
DRACUT_INSTALL_LOG_TARGET and DRACUT_INSTALL_LOG_LEVEL were
introduced so dracut-install can use different settings from
DRACUT_LOG_TARGET and DRACUT_LOG_LEVEL.

This is needed since few gpio/pinctrl can be built as modules and are
useful on early boot.
One example is jetson-tx1 where sata and external mmc can work only
after loading pinctrl-max77620 and gpio-max77620 modules.
Having theses kind of drivers bundled into the initramfs will also
avoid some deferred probes.
V2: add pinctrl for all arches

since kmod-25 keyword "external" was implemented in order to avoid
additional actions(like weak-modules) when kernel was updated, which
makes it more simple while kernels' kabi were compatible.
but if move some special modules such as megaraid_sas, mpt3sas and
so on, to a external path like /opt/modules, these modules will not
be install to initramfs by default, which make the initramfs can't
be used to boot for disk detection failure.
according to kmod's document, you must specify a absolute path with
"external" keyword, so scan the lines in modules.dep that begin with
"/" and install them, to make sure necessary modules in external path
can be installed to initramfs too.

If a hisi_sas storage device is used as / during system install, the

This adds the same list of drivers we use for arm platforms for
aarch64 too, also add the DMA drivers there too as they can add
sigficant performance for some storage/usb and often need to be
present when the storage drivers load.

Contrary to previous intel pinctrl drivers, the cherryview driver can be
and usually is built as a module. However, it sets up the SDIO pinout
so sdhci can make use of the SD card reader, which may subsequently
hold a root file system on a card (bsc#998440).

This will bundle clock drivers into the initramfs on arm
Tested on ti dm8148-t410 where adpll is needed on 4.6+ kernel
This will avoid to rely on (maybe broken) bootloader clocks.
Theses modules are also usually loaded early. Having them bundled into
the initramfs will avoid lot of deferred probes and others delay.

The sdhci-pci module is currently not being included in the initramfs,
even though other sdhci modules are. This breaks boot on systems that
rely on this driver to access the root filesystem.
Instead of looking for modules that use sdhci_pltfm_init, look for
sdhci_add_host. I checked 3.18 kernel sources, and this change
does not remove any of the previously-matched SDHCI drivers.
It should result in the addition of sdhci-pci, sdhci-s3c, sdhci-spear
and sdhci-acpi.
As reported in https://bugs.mageia.org/show_bug.cgi?id=14799
the xhci module got splitted up in upstream linux merged during
3.18 release cycle:

The synthetic keyboard of a Gen2 Linux VM doesn't work before the
hyperv_keyboard module is loaded. Without it, we can't cancel the media check
phase if boot with rd.live.check option.
Gen1 Linux VM doesn't have the same issue because the host emulates the legacy
