[coreboot] Chainloading Windows from a Linux Payload

[Matt B]

Greetings,

From what I can find, Linux can only chainload another linux kernel. (via
kexec) Does this mean that a Linux payload like LinuxBoot cannot be used to
boot Windows or another OS, either directly or by chainloading another
payload from CBFS?

It's nice that a Linux payload can provide superior flexibility and
configurability than UEFI with the added benefit of a battle-hardened
environment, but the ability to only boot a Linux OS seems like a pretty
significant limitation (if this is indeed the case).

Sincerely,
    -Matt
