This was discussed a bit with the arm64 kernel maintainers (see [0]) and after discussing the pros and cons of adding this support in kernel-space v/s in user-space, we decided it makes more sense to add this support to the user-space kexec-tools. Note that this series adds support for unsigned arm64 Image.gz files only as signing an Image.gz type file is not a easy implementation from kexec-tools p-o-v. Also even standard signing tools like sbsign fail to recongize the Image.gz format: $ sbsign --key certs/signing_key.pem --cert certs/signing_key.pem Image.gz Invalid DOS header magic ... because that gzip file isn't a PE32+ that can be loaded by UEFI. So I will work on the same in coming days and try to send a RFC patchset for the same later on.
