Simon Glass	c627cfc14c	bootstd: Allow scanning for global bootmeths separately ... Typically we want to find and use global bootmeths first, since they have the best idea of how the system should boot. We then use normal bootmeths as a fallback. Add the logic for this, putting global bootmeths at the end of the ordering. We can then easily scan the global bootmeths first, then drop them from the list for subsequent bootdev-centric scans. This changes the ordering of global bootmeths, so update the bootflow_system() accordingly. Drop the comment from bootmeth_setup_iter_order() since this is an exported function and it should be in the header file. Signed-off-by: Simon Glass <sjg@chromium.org>	2022-08-12 08:17:11 -04:00
Simon Glass	2b80bc1eee	bootstd: Support bootflows with global bootmeths ... Add support for handling this concept in bootflows. Update the 'bootflow' command to allow only the normal bootmeths to be used. This alllows skipping EFI bootmgr and VBE, for example.

Simon Glass	eccb25cd59	bootstd: Allow the bootdev to be optional in bootflows ... With global bootmeths we want to scan without a bootdev. Update the logic to allow this. Change the bootflow command to show the bootdev only when valid. Signed-off-by: Simon Glass <sjg@chromium.org>	2022-08-12 08:17:11 -04:00
Simon Glass	a8f5be178d	bootstd: Add support for bootflows ... Add support for bootflows, including maintaining a list of them and iterating to find them. Signed-off-by: Simon Glass <sjg@chromium.org>	2022-04-25 10:00:04 -04:00
