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>

freescale: vsc3316_3308: fix header inclusion guard It seems like the header inclusion guard for some Freescale crosspoint switch header was misspelled. Make the preprocessor symbol for the #ifndef and #define lines the same, so that the double inclusion protection works as expected.

powerpc/common/vsc3316: remove const from vsc3316_config parameter define Since the parameters need to be modified according to different Serdes protocols at runtime, the const will block this.

powerpc/b4860qds: add workaround for XFI XFI does not work stable on current board, it's due to heat sink issue, to make it work stable the board needs additional heat sink, enable two XFI lanes only. Right now we do not have such an erratum for the issue, so use a define CONFIG_SYS_FSL_B4860QDS_XFI_ERR to identify it. The workaround will only be used in XFI protocols and only if the hwconfig indicates that XFI is prefered. A new VSC3308 config function is used instead of re-use the original function, to avoid making the function complex and ugly.
