This change reorganizes and cleanups our patches to reduce the patch number from 314 patches to 187. That's achieved by dropping patches that are later reverted and squashing fixes for earlier patches that introduced features. There are no code changes and the diff with upstream is the same before and after the cleanup. Having fewer patches makes easier to manage the patchset and also will ease to rebase them on top of the latest grub-2.04 release. Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

Subject: [PATCH] Add fw_path variable (revised)
|
|
|
|
This patch makes grub look for its config file on efi where the app was
|
|
found. It was originally written by Matthew Garrett, and adapted to fix the
|
|
"No modules are loaded on grub2 network boot" issue:
