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>

arm: socfpga: clock: Clean up pll_config.h Extract the clock configuration horribleness caused by pll_config.h in the following manner. First of all, introduce a few new accessors which return values of various clocks used in clock_manager.c and use them in clock_manager.c . These accessors replace those few macros which came from pll_config.h originally. Also introduce an accessor which returns the struct cm_config default configuration for the clock manager used in SPL. The accessors are implemented in a board-specific wrap_pll_config.c file, whose sole purpose is to include the qts-generated pll_config.h and provide only the necessary values to the clock manager. The purpose of this design is to limit the scope of inclusion for the pll_config.h , which thus far was included build-wide and poluted the namespace. With this change, the inclusion is limited to just the new wrap_pll_config.c file, which in turn provides three simple functions for the clock_manager.c to use.

arm: socfpga: Move wrappers into platform directory Move the wrappers for QTS-generated files into platform directory out of the board directory. The trick here is to add -I to CFLAGS such that it points to the board directory in source tree and thus the qts/ directory there is still reachable. Signed-off-by: Marek Vasut <marex@denx.de>

arm: socfpga: set the mpuclk divider in the Altera group register The mpuclk register in the Altera group of the clock manager divides the mpu_clk that is generated from the C0 output of the main pll. Without this patch, the default value of the register is 1, so the mpuclk will always get divided by 2 if the correct value is not set. For example, on the Arria5 socdk board, the MPU clock is only 525 MHz, and it should be 1.05 GHz. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
