SPDX: Convert all of our single license tags to Linux Kernel style 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> |

common: rework bouncebuf implementation The current bouncebuf API requires all parameters to be passed to both bounce_buffer_start() and bounce_buffer_stop(). Modify the bouncebuf start function to accept a state structure as a parameter, and only require that state struct to be passed to the stop function. This simplifies usage of the bounce buffer by clients. Don't modify the data pointer, but rather store the temporary buffer in this state struct. The bouncebuf code ensures that client code can always use a single buffer pointer in the state structure, irrespective of whether a bounce buffer actually had to be allocated. Move cache management logic into the bounce buffer code, so that each client doesn't have to duplicate this. I believe there's no need to invalidate the buffer before a DMA operation, since flushing the cache should prevent any write-backs. Update the MXS MMC driver for this change.
