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>

sunxi: Add i2c support Add support for the i2c controller found on all Allwinner sunxi SoCs, this is the same controller as found on the Marvell orion5x and kirkwood SoC families, with a slightly different register layout, so this patch uses the existing mvtwsi code.

sunxi: Complete i2c support for each supported platform Sunxi platforms come with at least 3 TWI (I2C) controllers and some platforms even have up to 5. This adds support for every controller on each supported platform, which is especially useful when using expansion ports on single-board- computers.

i2c: mvtwsi: Support for up to 4 different controllers Orion5x, Kirkwood and Armada XP platforms come with a single TWSI (I2C) MVTWSI controller. However, other platforms using MVTWSI may come with more: this is the case on Allwinner (sunxi) platforms, where up to 4 controllers can be found on the same chip.
