Hello, I am preparing to flash coreboot on a Thinkpad X230. Currently I use UEFI and systemd to boot Linux as the only operating system and I wish to change my configuration as little as possible. The most natural option for me would be to use TianoCore as payload, however Tiano seems to be still unstable and is not particularly well documented.
As an alternative I was considering using the kernel itself as payload. But what happens when I need to update the kernel? Will I need to hardware reflash coreboot with the new kernel? I wouldn't mind recompiling coreboot with a different kernel and software flashing, but I'd like to avoid having to dismantle the laptop every time I update the kernel. Can anybody clarify this for me please?
best regards

You can always kexec() into your new kernel. The one sitting in flash can be smart enough to interrogate your boot media and determine what to load. Then just kexec().
