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>

imx: ventana: remove dependence on EECONFIG_SATA eeprom feature bit The MSATA feature is a board-specific feature on Gateworks Ventana boards. In most cases a 2:1 mux will steer either PCIe or SATA to a miniPCIe socket through an MSATA_EN gpio. In these such cases assign the gpio in the board specific struct and use its presence to determine if we default the GPIO to PCIe and if we later steer it according to hwconfig.

imx: ventana: add fdt fixup to enable UHS-I support on selected boards UHS-I support is available on Ventana boards with micro-SD sockets depending on the board revision. For backwards compatibility to not break users who have old bootloaders and newer kernels the device-tree on boards with microSD disables UHS-I support by default by defining the no-1-8-v property in the esdhc controller node. For models/revisions that support switchable 1.8V/3.3V I/O which is detectable by the presence of a pull-down on the SD3_VSELECT pin we remove that property to enable support in the kernel. Additionally we add SD3_VSELECT to the pinmux for clarity (even though U-Boot does not currently support UHS-I modes requiring 1.8V I/O). Signed-off-by: Tim Harvey <tharvey@gateworks.com>
