This code is gated behind the CHAINLOADING define. To build a release-style m1n1 with chainloading for use with the installer or kmutil, use: make CHAINLOADING=1 RELEASE=1 To tell m1n1 to chainload another binary, use this var payload: chainload=<ESP partition UUID>;<file path> e.g. chainload=a17b7e46-e950-bb4f-bc82-8ab1047a058e;m1n1/m1n1.bin Closes: #154 Co-authored-by: Finn Behrens <me@kloenk.dev> Co-authored-by: Joey Gouly <joey.gouly@arm.com> Signed-off-by: Hector Martin <marcan@marcan.st>
