	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>
2017-10-02	Provide a generic io.h & address mapping functions	Paul Burton
	Most architectures currently supported by U-Boot use trivial implementations of map_to_physmem & virt_to_phys which simply cast a physical address to a pointer for use a virtual address & vice-versa. This results in a lot of duplicate implementations of these mapping functions. The set of functions provided by different architectures also differs, with some having implementations of phys_to_virt & others not. A later patch will make use of phys_to_virt in architecture-neutral code, and so requires that it be provided for all architectures. This patch introduces an asm-generic/io.h which provides generic implementations of address mapping functions, allowing the duplication of them between architectures to be removed. Once architectures are converted to make use of this generic header it will also ensure that all of phys_to_virt, virt_to_phys, map_physmem & unmap_physmem are provided. The 2 families of functions differ in that map_physmem may create dynamic mappings whilst phys_to_virt may not & therefore is more limited in scope but doesn't require information such as a length & flags. This patch doesn't convert any architectures to make use of this generic header - later patches in the series will do so.
