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>

MIPS: sync I/O related header files with linux-4.4 Mainly sync asm/io.h to get a working ioremap() implementation as well as the full set of I/O accessors. Pull in additional header files to make this work. Furthermore port over the directory 'arch/mips/include/asm/mach-generic/' with contains default definitions for I/O and memory spaces and default implementations for mapping those spaces. All files in that directory can be overwritten by a SoC/machine. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

/*
* Sane hardware offers swapping of PCI/ISA I/O space accesses in hardware;
* less sane hardware forces software to fiddle with this...
*
* Regardless, if the host bus endianness mismatches that of PCI/ISA, then
* you can't have the numerical value of data and byte addresses within
* multibyte quantities both preserved at the same time. Hence two
* variations of functions: non-prefixed ones that preserve the value
* and prefixed ones that preserve byte addresses. The latters are
* typically used for moving raw data between a peripheral and memory (cf.
* string I/O functions), hence the "__mem_" prefix.
