compressed/raw is nothing the payload needs to concern itself with with
coreboot.

Transitioning back to coreboot doesn't happen (what for?), though we
have bayou which allows handling multiple payloads with proper exit
semantics.

memory size is in cbtable, payloads are ELF by convention (worst case
would be to objcopy a binary uboot image into ELF to use that), stack
location and relocation are payload matters (ie. nothing coreboot cares
about), though optional relocation support might be provided by
libpayload in the not too far future.

In the context of coreboot: why?

Code duplication? *shudder*
