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> 2018-05-07 06:58:06 +09:00			`// SPDX-License-Identifier: GPL-2.0+`
ARM64: poplar: hi3798cv200: u-boot support for Poplar 96Boards This port adds support for: 1) Serial 2) eMMC 3) USB It has been tested with ARM TRUSTED FIRMWARE running u-boot as the BL33 executable [see board's README] eMMC has been tested for reading and booting the loader and linux kernels as well as saving the u-boot environment. USB has been tested with ASIX networking adapter and SanDisk 7.4GB drive. PSCI has been tested via the reset call (PSCI executes from DDR) The firwmare upgrade process has been tested via TFTP and USB FAT filesystem containing the fastboot.bin image in one of the partitions.

poplar: fix boot failure caused by serial driver change Commit 4687919684e0 ("serial: Remove DM_FLAG_PRE_RELOC flag in various drivers") essentially drops flag DM_FLAG_PRE_RELOC from serial_pl01x driver for Poplar platform, because the platform falls into the following strategy category made by the commit. Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Before the commit lands, Poplar platform works by statically declaring pl011 serial device via U_BOOT_DEVICE() with DM_FLAG_PRE_RELOC flag set in the driver. But since Poplar also supports device configuration from device tree, the commit practically drops the flag for Poplar, and hence breaks the platform from booting. This patch changes platform code and device tree to initiate pl011 serial device from device tree rather than static declaration, so that above strategy about DM_FLAG_PRE_RELOC applies to Poplar, and therefore the reported boot failure gets fixed.
