2022-06-07Docs: Reword and extend SeaBIOS descriptionBill XIE
The sentence about using SeaBIOS as secondary payload sounded confusing, so reword it. While at it, improve and extend on SeaBIOS features.

2022-05-24payloads/external: Add more option related to SeaBIOS and GRUB2Bill XIE
Also known as "SeaGRUB", running GRUB2 atop SeaBIOS proves to be a useful configuration, since SeaBIOS has improved its hardware compatibility. For example, some USB drive can work under SeaBIOS but do not work under native GRUB2, and GRUB2 can use BIOS call (provided by SeaBIOS) as a fallback method to access hardware if it is present. But more option is added addition to "SeaGRUB": now GRUB2 and SeaBIOS can be built as secondary payloads, and "SeaGRUB" is now implemented as "Primary SeaBIOS + Secondary GRUB2 (selected) + config files".

2021-05-13payloads/Tianocore: Update default build target, simplify build optionsMatt DeVillier
Drop the deprecated COREBOOTPAYLOAD option, and replace it with MrChromebox's updated UefiPayloadPkg option. Simplify the Kconfig options to make it easier to build from upstream edk2 master. Drop the TIANOCORE_USE_8254_TIMER Kconfig option since it applied only to CorebootPayloadPkg. Clean up the Makefile now that we're only building from a single Tianocore package/target. Test: build/boot qemu Q35 target with both UefiPayload and Upstream options.

Neither payloads nor distributors are an integral part of the coreboot source tree, but they're very important parts of the coreboot ecosystems, so add some descriptions.
