Can I compile it 64bit?
As long as you keep the 32bit entry point around, yes (which I think is the default configuration for x86_64 kernels). In kconfig/menuconfig/..., select a linux payload, and point to the bzImage file. That should work (and this part of coreboot is pretty well testable with our QEmu targets, in case you want to try it out first).
Is there any further documentation on this?
Sadly documentation is not a strength in this project.
I found something on the wiki https://www.coreboot.org/Board:tyan/s2891#LAB_payload
The kexec information there is probably still useful, the buildrom stuff is horribly outdated.
