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>

mx6: Add board mx6memcal for use in validating DDR This is a virtual "board" that uses configuration files and Kconfig to define the memory layout used by a real board during the board bring-up process. It generates an SPL image that can be loaded using imx_usb or SB_LOADER.exe. When run, it will generate a set of calibration constants for use in either or both a DCD configuration file for boards that use u-boot.imx or struct mx6_mmdc_calibration for boards that boot via SPL. In essence, it is a configurable, open-source variant of the Freescale ddr-stress tool. https://community.nxp.com/docs/DOC-105652 File mx6memcal_defconfig configures the board for use with mx6sabresd or mx6qsabreauto.

mx6memcal: enable SDP support The initial implementation of mx6memcal reset the CPU after running the memory calibration procedure because the generic board has no information about which boot devices are available. Now that we have SDP support in SPL, use it to allow a full U-Boot to be uploaded (i.e. to use "mtest").
