[coreboot] Beginners questions

[JPT]

Hi,

I successfully built coreboot for my X220.

Now I got a few questions:
- tiano and grub payloads fail building. Is this normal? I build from
master branch. (there seems to be a bug with config, conflicting SeaBIOS
and Tianocore)

- which branch or tag should I build stable images from?

- 700 KB Tianocore should fit into 8 MB flash?

- what is the preferred payload for a recent 64 bit Linux?

- which payloads deliver the usual BIOS functions OSes rely on, like
ACPI etc?

- Wow, SeaBIOS almost boots DOS, where original UEFI couldn't at all.
anyone interested in bug-reports regarding the "almost"?

thank you very much
