X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-favicon.png?a=commitdiff_plain;h=7a0d88076b9cd8ccc88d41383f92ac2494d4168e;p=u-boot.git

Add in the ability to load and boot an uncompressed kernel image during the Falcon Mode boot sequence.

This is required for architectures which do not support compressed kernel images (i.e. ARM64).  This is only used while not booting via FIT image.
