[PATCH v3 0/2] Fix and adjust ukify packaging

[PATCH v3 0/2] Fix and adjust ukify packaging

[Koen Kooi]

This packages up 'ukify' from systemd to be used as an, optional,
stand-alone tool to generate and inspect Unified Kernel Images (UKIs) on
the target. The original plan was to add this to sytemd-boot, as
systemd-boot-native already handles 'ukify', but the recent systemd
upgrade snuck in 'ukify' under the radar. So package it up properly from
inside the systemd recipe.

Changes since v2:
 * Add python3-pyzstd to ptest-packagelist.inc, as suggested by Mathieu Dubois-Briand
Changes since v1:
 * Adjusted pyzstd patch to not specify an upper limit to the setuptools
   version, as suggested by Alexander Kanavin.

Koen Kooi (2):
  python3-pyzstd: import 0.17.0 from meta-python
  systemd: package 'ukify' seperately

[PATCH v3 1/3] python3-pyzstd: import 0.17.0 from meta-python

[Koen Kooi]

From the upstream website:
	Pyzstd module provides classes and functions for compressing and
	decompressing data, using Facebook's Zstandard (or zstd as short name)
	algorithm.

This recipe is being moved over for systemd 258.x, the 'ukify' tool
depends on this.

Hi Koen,

Thanks for the new version.

You also need to add a SUMMARY line here. QA complains:

Thanks! I'll try to send a v4 before heading out for the holidays, I appreciate your feedback and help with this. It has been a looooooong time since I had to add a new recipe to OE-core.

[PATCH v3 2/3] systemd: package 'ukify' seperately

[Koen Kooi]

The upgrade to 258.x started shipping 'ukify' by default, but didn't
adjust the runtime dependencies. Add the python modules 'ukify' imports
and split out the package to avoid dragging in gigabytes of python just
plain systemd.

Succesfully tested at runtime on:
* RB1-core-kit, using u-boot EFI mode + systemd-boot
* RB3gen2-core-kit, using Qualcomm UEFI + systemd-boot
* Rubikpi3, using Qualcomm UEFI and type 2 boot
* Beagleboneblack using u-boot UFI mode + systemd-boot
