2020-12-22fsp: Move and rename fsp_types.h fileSughosh Ganu2-63/+2
The fsp_types.h header file contains macros for building signatures of different widths. These signature macros are architecture agnostic, and can be used in all places which use signatures in a data structure. Move and rename the fsp_types.h under the common include header.

2020-09-25x86: hob: Try to show a name instead of a GUIDSimon Glass1-0/+25
GUIDs are one of the seven evils of the computer world. They obfuscate the meaning and require people to look up long hex strings to decode it. Luckily only a miniscule fraction of the 10^38 possible GUIDs are in use. Add a way to decode the GUIDs known to U-Boot. Add a few more to the list for good measure.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini9-18/+9
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>
