2021-08-02global: Convert simple_strtoul() with hex to hextoul()Simon Glass1-3/+3
It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass2-0/+2
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.

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.

2020-09-01x86: mtrr: Fix parsing of "mtrr list" commandWolfgang Wallner1-1/+2
The command 'mtrr' does not recognize the 'list' subcommand any more since the code restructuring in commit b2a76b3fe75a ("x86: mtrr: Restructure so command execution is in one place"). The if-else parsing the command arguments does not take 'list' into account: the if-branch is intended for no subcommands, the else-branch is intended for the non-list subcommands (which all expect additional arguments). Calling the 'mtrr list' subcommand leads to a "return CMD_RET_USAGE" in the else-branch. Fix this by changing the else-branch to explicitly checking for if (cmd != 'l').

2020-05-19command: Remove the cmd_tbl_t typedefSimon Glass4-10/+12
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini3-7/+3
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>
