[Buildroot] [PATCH v9 02/11] boot/ti-k3-image-gen: new package

[Andreas Dannenberg]

Hi Bryce, All,
first I wanted to say my apologies from the lack of progress on updating
this series, the v9 rework got caught up in my summer break, and then TI
has since released new U-Boot 2023.04 and Kernel 6.1-based SDKs for the
AM62x/AM64 devices which should now be the updated goal for this
upstream effort. In addition to newer components this should actually
help/simplify some of the boot image creation and secure boot related
"TI quirks", for example we'll no longer need the ti-k3-image-gen and
ti-core-secdev-k3 packages (yeey!) as those items will be taken care of
by U-Boot (via binman). I'm planning on making time to pick this back up
over the next few weeks and work on a v10 series with those changes plus
applicable feedback that was provided on v9.

As for your feedback, see below...

Good find, I'll experiment with this in the context of v10 and see how
this behavior can be improved.
