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>

arm: mvebu: drivers/ddr: Add DDR3 driver with training code from Marvell bin_hdr This patch adds the DDR3 setup and training code taken from the Marvell U-Boot repository. This code used to be included as a binary (bin_hdr) into the AXP boot image. Not linked with the main U-Boot. With this code addition and the following serdes/PHY setup code, the Armada-XP support in mainline U-Boot is finally self-contained. So the complete image for booting can be built from mainline U-Boot. Without any additional external inclusion. Hopefully other MVEBU SoC's will follow here. Support for some SoC's has been removed in this version. This is: MV_MSYS: The code referred to by the MV_MSYS define is currently unused. And its not really planned to support this in mainline. So lets remove it to make the code clearer and increase the readability. MV88F68XX (A38x): The code referred to by the MV88F68XX define (A38x) is currently unused. And its partial and not sufficient for this device in this stage. So lets remove it to make the code clearer and increase the readability. MV88F66XX (ALP): The code referred to by the MV88F66XX define is currently unused. And its not really planned to support this in mainline. So lets remove it to make the code clearer and increase the readability. MV88F78X60_Z1: The code referred to by the MV88F78X60_Z1 define is currently unused. As the Z1 revision of the AXP is not supported in mainline anymore. So lets remove it to make the code clearer and increase the readability. Remove support for Z1 & A0 AXP revisions (steppings). The current stepping is B0 and this is the only one that is actively supported in this code version. Tested on AXP using a SPD DIMM setup on the Marvell DB-MV784MP-GP board and on a custom fixed DDR configuration board (maxbcm). Note: This code has undergone many hours of coding-style cleanup and refactoring. It still is not checkpatch clean though, I'm afraid. As the factoring of the code has so many levels of indentation that many lines are longer than 80 chars. This might be some task to tackly later on.
