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

2018-05-07T13:34:12Z

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

nios2: Use asm-generic/io.h

2017-10-03T01:52:23Z

Convert the nios2 architecture to make use of the new asm-generic/io.h to provide address mapping functions. As nios2 actually performs non-identity mapping between physical & virtual addresses we can't simply make use of the generic functions, with the exception of being able to drop our no-op unmap_physmem() and definitions of unused map flags. Feedback from architecture maintainers is welcome. Signed-off-by: Paul Burton Cc: Thomas Chou

nios2: change virt_to_phys to use physaddr_mask in global data

2015-11-06T01:14:11Z

As virt_to_phys() is used a lot in DMA transfer, change it to use physaddr_mask in global data. This will save an "if" statement and get a little faster. Signed-off-by: Thomas Chou Acked-by: Marek Vasut
