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>

Introduce addr_map library Add a library that helps in translating between virtual and physical addresses. This library can be useful as a simple means to implement map_physmem() and virt_to_phys() for platforms that need functionality beyond the simple 1:1 mapping.

lib: addr_map: Move address_map[] type to the header file At present address_map[] is static and its type is unknown to external modules.

addrmap: Support on sandbox Update this feature so that it works on sandbox, using a basic identity mapping. This allows us to run the 'ut addrmap' test. Also fix up the test to use the correct macros to access the linker list, so that the 'ut addrmap' command actually works. Signed-off-by: Simon Glass <sjg@chromium.org>
