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>

/* Micron MT41J512M8RH-125 on EVM v1.5 */
ARM: AM335x: Enable DDR dynamic IO power down This patch enables dynamically powering down the IO receiver when not performing a read on boards using DDR3. This optimizes both active and standby power consumption. This bit is not set on EVM SK and EVM 1.5 and later boards. Setting the same. This has been tested on PG2.0 EVM1.5, EVM1.2, EVM-SK, BBB.

am33xx: Stop modifying certain EMIF4D registers Based on the definitive guide to EMIF configuration[1] certain registers that we have been modifying (and are documented registers) should be left in their reset values rather than modified. This has been tested on AM335x GP EVM and Beaglebone White.

am33xx: Correct and clean up ddr_regs struct The ddr_regs struct was incorrectly offset after the dt0wiratio0 entry. Correct this by documenting a missing register that will be used at some point in the future (when write leveling is supported). Further, the cmdNcs{force,delay} fields are undocumented and we have been setting them to zero, remove. Next, setting of the 'DATAn_REG_PHY_USE_RANK0_DELAYS field belongs with the rest of the ddr_data entries, so program it there. Finally, comment on how we are configuring the DATA1 registers that correspond to the DATA0 (dt0) registers defined in the struct. Signed-off-by: Tom Rini <trini@ti.com>
