2023-03-13efi: Support a 64-bit frame buffer addressSimon Glass1-4/+6
The current vesa structure only provides a 32-bit value for the frame buffer. Many modern machines use an address outside the range. It is still useful to have this common struct, but add a separate frame-buffer address as well. Add a comment for vesa_setup_video_priv() while we are here.

2021-03-27video: Fix video on coreboot with the copy bufferSimon Glass1-5/+2
The copy buffer, if enabled, prevents booting from coreboot correctly, since no memory is allocated for it. Allow it to fall back to disabled in this situation. This ensures that a console is displayed, even if it is slow. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-3/+3
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-07-09video: pci: Set up the copy framebufferSimon Glass1-1/+21
When using a copy framebuffer we need to tell the video subsystem its address. U-Boot's normally allocated framebuffer is used as the working buffer, but nothing is displayed until it is copied to the copy framebuffer. For this to work the video driver must request that a framebuffer be allocated separately from the hardware framebuffer, so add a check for that. Also add a log category so that logging appears correctly. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Anatolij Gustschin <agust@denx.de> Tested-by: Bin Meng <bmeng.cn@gmail.com>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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 <trini@konsulko.com>
