lmb: Always compile arch_lmb_reserve() into U-Boot on arc 2021-09-23T18:15:32+00:00 Marek Vasut marek.vasut@gmail.com 2021-09-10T20:47:08+00:00 cfa1971977bbf2c5c4aa076924ca36f964a16a1a The arch_lmb_reserve() is called by lib/lmb.c lmb_reserve_common() even if CMD_BOOTM is not enabled. However, the arc variant of arch_lmb_reserve() is only compiled in if CMD_BOOTM is enabled. This currently does not trigger build error, because there is an empty weak implementation of arch_lmb_reserve(), however that is not the function that should be used on arc. Fix this by moving the arch_lmb_reserve() implementation into common code and always compile it in.

common: Drop asm/global_data.h from common header 2021-02-02T20:33:42+00:00 Simon Glass sjg@chromium.org 2020-10-31T03:38:53+00:00 401d1c4f5d2d29c4bc4beaec95402ca23eb63295 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.

SPDX: Convert all of our single license tags to Linux Kernel style 2018-05-07T13:34:12+00:00 Tom Rini trini@konsulko.com 2018-05-06T21:58:06+00:00 83d290c56fab2d38cd1ab4c4cc7099559c1d5046 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>
