[Buildroot] [PATCH v2 0/3] LS1028ARDB improvements

[Francois Perrad]

The package qoriq-cadence-dp-firmware is dedicated to the NXP LS1028 SoC.
It was introduced since BR 2022.02 from a Changming Huang's serie (5 versions between 2019-Nov and 2020-Feb).
This serie tried to introduce the board NXP LS1028ARDB with a partition boot.vfat containing
the kernel image, the dtb and the cadence DP firmware.

The board NXP LS1028ARDB was introduced on 2022-Aug from my own serie.
This serie uses a single rootfs partition and a extlinux.conf file.
The patch concerning the cadence DP firmware has been set aside at this time (between v3 and v4).

Now, this current serie finalizes the support of the board NXP LS1028ARDB,
especially the point concerning the cadence DP firmware.

[Buildroot] [PATCH v2 1/3] package/qoriq-cadence-dp-firmware: add install in target

[Francois Perrad]

This firmware is loaded by u-boot.
This firmware must be shipped in /boot with the kernel & dtb,
there are 2 cases of installation:
- in $(TARGET_DIR)/boot, in order to be in the rootfs
- in $(BINARIES), in order to be bundled into a boot partition

Thanks, series applied to next. Along the way, I've reworded a bit the
commit of PATCH 1/3 to make it clearer.

Best regards,
