Linux 6.7-rc1 looks for the venus (video) firmware in
qcom/venus-1.8/venus.mbn instead of qcom/venus-1.8/venus.mdt.
Let's install it in both places with a symlink so that the firmware
packages work for both older and newer Linux versions.
[ci:ignore-count]: lots of packages
[ci:skip-build] already built successfully in CI
Strictly speaking firmware-bq-picmt is not needed anymore because
the msm-firmware-loader can be used to load the picmt firmware from
the firmware partitions. However, this package contains quite recent,
largely unmodified firmware from Qualcomm so it still seems useful
to keep if someone wants to test more recent firmware on some other
device (provided that their device does not verify firmware signatures).
To make this firmware package consistent with firmware-qcom-db410c,
squash the firmware blobs using pil-squasher so only one file needs
to be loaded rather than many small ones.
Right now we have all firmware packages under firmware/*.
This is problematic for mainly two reasons:
- It's not immediately clear which firmware packages we need to keep
when forking a new stable branch. (Where we delete testing devices
at the moment...) We might end up deleting firmware packages that
are actually used by one of the devices in community.
- When backporting devices to the stable we cannot just cherry-pick
the commit that moved the device to community (since it does not
contain the firmware package). Instead we need to cherry-pick
earlier commits as well, which may touch a lot of deleted files
in the testing directory.
Let's make this consistent by also placing the firmware packages in
the device/* directory. We already have the common firmware- prefix
to distinguish them from device/kernel packages, which are already
both under the device/* directory.
