2025-02-03vbe: Add an implementation of VBE-ABrecSimon Glass
So far only VBE-simple is implemented in U-Boot. This supports a single image which can be updated in situ. It is often necessary to support two images (A and B) so that the board is not bricked if the update is interrupted or is bad. In some cases, a non-updatable recovery image is desirable, so that the board can be returned to a known-good state in the event of a serious failure. Introduce ABrec which provides these features. It supports three independent images and the logic to select the desired one on boot. While we are here, fix a debug message to indicate the function it called. Provide a maintainers entry for VBE. Note that fwupdated only supports VBE-simple so far, but supports for ABrec will appear in time. Signed-off-by: Simon Glass <[email protected]>
2024-10-11include: Use CONFIG_XPL_BUILD instead of CONFIG_SPL_BUILDSimon Glass
Use the new symbol to refer to any 'SPL' build, including TPL and VPL Signed-off-by: Simon Glass <[email protected]>
2022-10-31vbe: Record which phases loaded using VBESimon Glass
We expect VPL and SPL to load using VBE. Add a record of this so we can check it in U-Boot proper. Signed-off-by: Simon Glass <[email protected]>
2022-10-31vbe: Support selecting operations by SPL phaseSimon Glass
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.

2022-08-12video: Renname vbe.h to vesa.hSimon Glass
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 Signed-off-by: Simon Glass <[email protected]>

Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <[email protected]>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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. Signed-off-by: Tom Rini <[email protected]>

2016-10-11dm: video: Add driver-model support to vesa graphicsSimon Glass
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. Signed-off-by: Simon Glass <[email protected]> Reviewed-by: Bin Meng <[email protected]>

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. Signed-off-by: Bin Meng <[email protected]>
