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>

nvme: Add NVM Express driver support 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.

nvme: Split out PCI support Apple SoCs have an integrated NVMe controller that isn't connected over a PCIe bus. In preparation for adding support for this NVMe controller, split out the PCI support into its own file. This file is selected through a new CONFIG_NVME_PCI Kconfig option, so do a wholesale replacement of CONFIG_NVME with CONFIG_NVME_PCI.

Move most CONFIG_HAVE_BLOCK_DEVICE to Kconfig config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE based on a list of enabled options. Moving HAVE_BLOCK_DEVICE to Kconfig allows us to drastically shrink the logic in config_fallbacks.h Signed-off-by: Adam Ford <aford173@gmail.com> [trini: Rename HAVE_BLOCK_DEVICE to CONFIG_BLOCK_DEVICE] Signed-off-by: Tom Rini <trini@konsulko.com>

This option enables support for NVM Express devices.
It supports basic functions of NVMe (read/write).
