The watchdog module pulls in the device specific watchdog if that
module is enabled, but in the case where we need a generic initrd
we don't get all watchdog drivers which means if we have a watchdog
enabled for that usecase it may get kicked too late in the boot
process so we need the drivers in the initrd for the generic case too.

`$_hostonly_drvs` contained multiple arguments and was quoted.
This patch converts `_hostonly_drvs` into an associative array, which
enables easy deduplication and proper quoting in bash.

Reset controllers might be needed by some of the devices used in the
initrd. Particularly on the Raspberry Pi 4, 'xhci-pci' depends on a
platform specific reset controller.

External Memory Controller (EMC) drivers can be built as a module.
On Tegra, this allows tegra_drm to load faster and without deferred
probes, instead of waiting for the rootfs for the tegra*_emc dependencies.
Tested on jetson-tk1 and ac100.

Otherwise e.g. the xts(aes) implementation provided by the vmx_crypto
module (which does usually get included on ppc64le) fails to initialize
when xts is built as a module (CONFIG_CRYPTO_XTS=m), because it can't
instantiate the fallback generic xts(aes) implementation (needs the
generic xts module).

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

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.

This adds the same list of drivers we use for arm platforms for

sigficant performance for some storage/usb and often need to be

Contrary to previous intel pinctrl drivers, the cherryview driver can be

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.
