efi_loader: correctly handle mixed hashes and signatures in db

2022-01-29T09:23:40+00:00

A mix of signatures and hashes in db doesn't always work as intended.
Currently if the digest algorithm is not explicitly set to sha256 we
stop walking the security database and reject the image.

That's problematic in case we find and try to check a signature before
inspecting the sha256 hash.  If the image is unsigned we will reject it
even if the digest matches.

Since we no longer reject the image on unknown algorithms add an explicit
check and reject the image if any other hash algorithm apart from sha256
is detected on dbx.

efi: Locate all block devices in the app

2021-12-31T05:45:01+00:00

When starting the app, locate all block devices and make them available
to U-Boot. This allows listing partitions and accessing files in
filesystems.

EFI also has the concept of 'disks', meaning boot media. For now, this
is not obviously useful in U-Boot, but add code to at least locate these.
This can be expanded later as needed.

We cannot use printf() in the early stub or app since it is not compiled
in
