The nodes "/dev/ramX" and "/dev/loopX" are mounted on boot.
Each node calls the mount.sh script, but they are not mounted
because these nodes are blacklisted in the "blacklist.conf" file.
In the ccmp13 adding this modification in the rule saves
around 4 seconds per boot.
In the ccmp15 and ccimx6ul around 2 seconds are saved.

The ccmp1 has two MTD partitions (UBI, UBI_2) with different system
volumes.
Previously, the fact of having two ubi devices was taken as proof of
being on a multi-MTD system (one that has one UBI volume per partition).
Instead, this commit reformulates the condition to having a partition of
the same name than the UBI volume.

When the system runs as read-only with '/etc' overlayfs enabled, '/sbin/init' is not a symlink
to 'systemd', but '/sbin/init.orig' is. This causes the script to wrongly think than 'systemd'
is not being used. The outcome is that partitions are not being automatically mounted in R/O
systems running in mmc with '/etc' overlayfs enabled, as the specific '/usr/bin/systemd-mount'
binary needs to be invoked in these cases.
The proposed fix performs a second check with '/sbin/init.orig' to determine whether systemd is
being used or not. While on it, add an early check to determine if the partition is already
mounted to exit the script.

For devices running 'systemd', the mount process is done through 'systemd-mount', which
spawns a system unit. Trying to mount the partition again throws an error stating that a
unit with the same name is already running. To avoid it, check if the unit is already
spawned before mounting the partition and, if so, just restart the unit.

This commit fixes the issue in Jira
https://onedigi.atlassian.net/browse/DEL-7827 (and in GitHub
91bfa01a52#),
that is being manifest again in a CC6UL with 1GB although it may affect other
hardware.
Partitions are mounted:
* For multi-MTD systems, when an MTD subsystem event is received.
* For single-MTD systems, when a UBI subsystem event is received.
This commit avoids process UBI subsystem events in multi-MTD systems.
The automount rules filter UBI subsystem events to only process 'ubi0*' (the
only UBI device/volumes in a single-MTD) and then the executed script
'mount_digiparts.sh' checks for the existance of '/dev/ubi1' node to consider
the system multi-MTD instead of using 'singlemtdsys' U-Boot variable that only
exists on CC6UL.

According to udev documentation running programs that access to mount/umount
filesystems is not allowed due to the default sandbox that is enforced on
systemd-udevd.service, so on systemd systems we must to use systemd-mount
binary instead of mount. Also systemd-mount does not support mount ubi devices
by volume name, so we need to use the absolute device path.

On the CCMP1 SOMs, we only consider a single system partition called UBI,
with many UBI volumes.
The variable 'singlemtdsys' allowed to change between this and
a system with multiple MTD partitions with one UBI volume each
(old approach on CC6UL).
This commit removes the variable and uses the logic as if it was set.

This code path was added in the context of single MTD layout support for
ccimx6ul boards, but it was being executed in the default storage layout use
case as well. This could trigger a race condition in which one code path
deletes the mount point while the other one is still setting it up, causing
partitions to not be mounted automatically (specifically, the "update"
partition).
Since both code paths are mutually exclusive in our implementation, reflect
this by making sure that the single MTD layout path is executed only when said
layout is enabled in the U-Boot environment.

Default poky's version of the 'mount.sh' script doesn't account
for the possibility of udev calling twice the script for the 'add'
action. This has been observed on USB sticks connected to a USB hub
and, although the script eventually fails, for already mounted
partitions, in that case the script tries to remove the created
mountpoint, when it shouldn't.
This patch checks for already mounted partitions earlier (before
creating the mount point) and returns with no actions.
The patch that it adds (with respect to poky's thud default) is
the following:

The current scripts used the standard mount binary at /bin/mount
for mounting the partitions. Systemd however seems to have a monitor
that eventually umounts such partitions if not mounted by systemd's
specific command 'systemd-mount`.
For platforms using systemd, we need to use this binary together with
parameter --no-block so that partitions are mounted correctly during
the boot process.
This commit merges the two scripts for Digi-handled partitions into
just one:
mount_bootparts.sh
\
+--> mount_digiparts.sh
/
mount_partition.sh
The merged script:
- checks if running with systemd, to use its binary.
- checks if running with busybox, to not use the unsupported '-o'
attribute.
- checks if mounting the 'linux' partition, to mount it read-only.
- checks for already-attached UBI devices, to avoid re-attaching.
This commit also combines the Digi-handled partitions (linux, update)
into the same udev rule, to simplify it, and breaks the rules lines
for readability.
