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 <trini@konsulko.com>
2017-10-02fs: btrfs: Add disk-to-cpu and cpu-to-disk conversion functionsMarek BehĂșn
BTRFS on disk structures are stored in Little Endian. Add functions to convert this structures to cpu and to disk format. On Little Endian hosts, these functions do nothing. On Big Endian the CALL_MACRO_FROM_EACH from variadic-macro.h is used to define all the members for each structure on which cpu_to_le* or le*_to_cpu is to be called.
