2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>

2011-12-16USB: ULPI: clean a mixup of return typesIgor Grinberg
Clean a mixup between u32 and int as a return type for functions returning error values. Use int as it is native (and widely used) return type. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il> Acked-by: Simon Glass <sjg@chromium.org>
2011-12-16USB: ULPI: switch argument type from u8 to unsignedIgor Grinberg
There is no benefit in using u8, so switch to unsigned to reduce the binary image size (by 20 bytes). Signed-off-by: Igor Grinberg <grinberg@compulab.co.il> Acked-by: Simon Glass <sjg@chromium.org>
2011-12-11USB: Add generic ULPI layer and a viewportJana Rapava
Add partial ULPI specification implementation that should be enough to interface the ULPI PHYs in the boot loader context. Add a viewport implementation for Chipidea/ARC based controllers.
