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+`
mips: Add MIPSfpga platform support MIPSfpga is an FPGA based dev platform. In a nutshell, its a microAptiv cpu core with lots of Xilinx IP blocks The FPGA dev board used is the Nexys4DDR board by Digilent.

board_f: Drop return value from initdram() At present we cannot use this function as an init sequence call without a wrapper, since it returns the RAM size. Adjust it to set the RAM size in global_data instead, and return 0 on success.

board_f: Rename initdram() to dram_init() This allows us to use the same DRAM init function on all archs. Add a dummy function for arc, which does not use DRAM init here.
