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>

2017-08-13nvme: Add NVM Express driver supportZhikang Zhang
NVM Express (NVMe) is a register level interface that allows host software to communicate with a non-volatile memory subsystem. This interface is optimized for enterprise and client solid state drives, typically attached to the PCI express interface. This adds a U-Boot driver support of devices that follow the NVMe standard [1] and supports basic read/write operations. Tested with a 400GB Intel SSD 750 series NVMe card with controller id 8086:0953.
