[coreboot] Problems changing payload on Intel Leaf Hill

[Cameron Craig]

Hi Tahnia,

I have attached the coreboot config and a coreboot patch (originally provided by Mario, thanks Mario).
I removed the Oxbow Hill parts of the patch.

My working combination:
- Coreboot v4.6 (with patch)
- Apollo Lake FSP MR2
- Tianocore commit 315d9d08fd77db1024ccc5307823da8aaed85e2f (with patches)

Other Tianocore versions may also work, but I haven't tested them.
I don't get any serial output from Tianocore so I suspect I don't have serial configured correctly.

Coreboot 4.6 does the fetch and patch of Tianocore for you, and it just worked.

Cheers,
Cameron
