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>

/**

* These two symbols are declared in a C file so that the linker
|
|
* uses R_ARM_RELATIVE relocation, rather than the R_ARM_ABS32 one
|
|
* it would use if the symbols were defined in the linker file.
|
|
* Using only R_ARM_RELATIVE relocation ensures that references to
|
|
* the symbols are correct after as well as before relocation.
|
|
*
|
|
* We need a 0-byte-size type for these symbols, and the compiler
|
|
* does not allow defining objects of C type 'void'. Using an empty
|
|
* struct is allowed by the compiler, but causes gcc versions 4.4 and
|
|
* below to complain about aliasing. Therefore we use the next best
|
|
* thing: zero-sized arrays, which are both 0-byte-size and exempt from
|
|
* aliasing warnings.
