On the multi-MTD layout (default) the 'data' UBI volume is never created
and thus not mounted by the system. This is because with this layout, the
creation of the UBI volume is done by the 'update' command, but nobody
updates this partition cause DEY doesn't generate an image for it.
We want the 'data' UBI volume to be created so that the CC6UL can connect
to the regular Remote Manager URI and store the certificate in it.
As long as a UBI volume is created, Linux will mount it, so this commit
erases the partition and creates the UBI volume.
The same goes for the 'update' partition. The installer was relying on the
recovery mechanism to wipe this partition, but this is not longer required
with UBI. As long as the installer erases the partition and creates the
volume, Linux will be able to mount it, so the boot in recovery mode has
been removed from the script.
Note: the formatting is only done for multi-MTD layout; the ubivolscript
creates all volumes for single-MTD layout.

Programming an encrypted bootloader can only be done after the
secure keys have been programed on the OTP bits, and the device
has been closed. Programming on an open device would result in a
non-secure configuration or a non-bootable device after the
close operation.
Create functions to detect the current TrustFence status and exit
the install script if the device is open and the artifacts are
encrypted.

The `-t` option to program images with TrustFence didn't make
much sense because the install script is dynamically generated
at build-time with the name of the boot artifacts containing
"signed/encrypted" on their filenames.
This commit:
- Removes `-t` option to simplify the script.
- Determines if programming a signed/encrypted bootloader by
looking at the bootloader filename.
- For NXP platforms, reworks the function that updates the
bootloader to properly program only-signed bootloaders (currently
wrongly using `trustfence update`)

The USB and SD installers are U-Boot scripts that are practically
identical.
Merge them into a single template with a couple of machine variables that
determine the default device index in U-Boot for the USB or the microSD
card.
Do dynamic substitutions to create the two installers out of the template.

The installer uses the regular rootfs filename or falls back to search
for a squashfs (read-only) rootfs image.
The UUU installers of eMMC-based platforms use an if/elif/else structure
to determine which file exist (in order of preference). Replicate this
structure on the rest of platforms and installers.
This avoids printing an error message if the default rootfs does not exist
but the read-only one does.
Also, reset 'rootfstype' variable if the default rootfs file exists, which
allows to install regular images over a previous read-only system.

This commit updates the installer scripts to support CCMP1 platforms under
Yocto 5.0, aligning them with the current behavior used for CCMP2.
Changes include:
- Adding support for the metadata partition, which is now required
- Including the optee/opteemin flavors in boot artifact filenames
- Ensuring the script structure and logic remain consistent with CCMP2 install scripts

Both boot artifacts now use the same signed label, so this commit removes
unnecessary logic and updates the UUU install script to support the new boot
artifact naming. It also fixes the detection of signed artifacts by checking
for the presence of the FIP artifact, instead of relying on a U-BOOT artifact
that does not exist on this platform.

Assignment of variable 'force_erase' was done without escaping quotes
which led to wrong assignment and the script not forcing the erasure of
NAND partitions.
While on it, remove it from ccmp1 scripts where its use makes no sense
as the 'ubivolscript' script takes care of erasing the partitions.

Device tree overlays now have the extension 'dtso' that
distinguishes them from board 'dts' files, so there is
no need for a prefix '_ov_' to tell if a file contains
a DT overlay.
To make them shorter and easier to tell the platform they
are for, change the filename format to:
<platform-name>_<functionality>.dtso
where <platform-name> can be the name of the SOM or the
name of the DVK, so there is no need either to specify
'som' or 'board' on the filename.

When running the installation script on variants with larger NANDs, two of the
script's commands take longer than our intended timeouts under specific
circumstances:
* When the variant has a NAND with 512 MiB or more and singlemtdsys is set
to "yes", running ubivolscipt takes longer than our 10 second timeout.
The larger the NAND storage size, the longer this command takes.
* When the variant has a 1 GiB NAND, singlemtdsys is set to "yes" and
dualboot is set to "no", the update of the recovery UBI volume takes
longer than our 15 second timeout.
In both of these cases, the script fails and the installation process cannot
continue. Apply the following changes to prevent this:
* Increase the ubivolscript timeout from 10 seconds to 30
* Increase the recovery update timeout from 15 seconds to 20
Also, remove the command immediately before ubivolscript is run, since said
command is already being run at the beginning of ubivolscript.

Add a check on the existence of the "temp-fitimg-loaded" environment
variable before setting it. It is needed, as with encrypted FIT images,
we need to decrypt them before accessing the boot script. In such cases,
u-boot sets that variable to "no" so the boot script does not override it,
and the FIT image is loaded again before the final boot to the OS.
