d8b7c34f98 vbe: Record which phases loaded using VBE
We expect VPL and SPL to load using VBE. Add a record of this so we can
check it in U-Boot proper.

70b26e4356 vbe: Support selecting operations by SPL phase
VBE supports booting firmware during the SPL phases, i.e. so that VPL can
start SPL and SPL can start U-Boot.

It also supports booting an OS, when in U-Boot.

As a first step towards these features, add functions to indicate the
current VBE phase. The firmware selection is done in VPL and the OS
selection is done in U-Boot proper.

cafe8712e8 video: Renname vbe.h to vesa.h
We want to use VBE to mean Verfiied Boot for Embedded in U-Boot. Rename
the existing VBE (Vesa BIOS extensions) to allow this.

Verified Boot for Embedded is documented doc/develop/vbe.rst

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

ee87ee82e1 dm: video: Add driver-model support to vesa graphics
Provide a function to run the Vesa BIOS for a given PCI device and obtain
the resulting configuration (e.g. display size) for use by the video
uclass. This makes it easier to write a video driver that uses vesa and
supports driver model.

153e1dda2f video: coreboot: Save VESA mode for future use
When booting as a coreboot payload, the framebuffer details are
passed from coreboot via configuration tables. We save these
information into vesa_mode_info structure for future use.
