2022-02-16payloads/external: add skiboot (for QEMU/Power9)Sergii Dmytruk
Add an option to build skiboot as a payload. This makes QEMU Power9 board simpler to use as skiboot is necessary anyway.

2021-02-07payloads: Force sub-make runs for in-tree payloadsNico Huber
The sub-process calls break make's dependency tracking, hence we have to always perform the calls if we want to allow automatic, incremental builds. We let each rule depend on a new, phony target `force-payload`. It has roughly the same effect as tagging all the targets as phony, but doing so would feel wrong as some of them are actual files.

Both GRUB and SeaBIOS can chainload lzma compressed payloads. Therefore it is beneficial to compress secondary payloads like Memtest86+, coreinfo, nvramcui,... for both size reasons and often also speed reasons since the limiting factor is generally the IO of the boot device. Tested with SeaBIOS and memtest86+ master on Thinkpad X220.
