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.

It's "correct" in so far as it works (the boards.cfg config stuff #defines things to 1), but I think you are right that it isn't the preferred style.

So rather than fix it to use #ifdef lets drop it. Rather than resend the entire series, here is v5.1 of this patch. > Other than this please add my: > > Reviewed-by: Stefan Roese <sr@denx.de> Thanks! 8<--------------------------------- >From 20704e35a41664de5f516ed0e02981ac06085102 Mon Sep 17 00:00:00 2001 From: Ian Campbell <ijc@hellion.org.uk> Date: Fri, 7 Mar 2014 04:29:39 +0000 Subject: [PATCH v5.1 7/8] sunxi: mmc support This adds support for the MMC controller on the Allwinner A20 (sun7i) processor.

sunxi: mmc: Move header to the driver directory The MMC controller driver is (and ought to be) the only user of these register definitions. Put them in a header next to the driver to remove the dependency on a specific ARM platform's headers. Due to the sunxi_mmc_init() prototype, the file was not renamed. None of the register definitions were changed.

sunxi: When we've both mmc0 and mmc2, detect from which one we're booting sunxi SOCs can boot from both mmc0 and mmc2, detect from which one we're booting, and make that one "mmc dev 0" so that a single u-boot binary can be used for both the onboard eMMC and for external sdcards. When we're booting from mmc2, we make it dev 0 because that is where the SPL will load the tertiary payload (the actual u-boot binary in our case) from, see: common/spl/spl_mmc.c, which has dev 0 hardcoded everywhere.
