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>

sunxi: add sun7i clocks and timer support. This patch adds the basic clocks and timer support for the Allwinner A20 (sun7i) processor. This code will not been compiled until the build is hooked up in a later patch. It has been split out to keep the patches manageable. Some of the code here is common to multiple sunxi subarchtectures, hence files are named sun4i which is the earliest similar variant.

sunxi: refactor serial base addresses to avoid asm/arch/cpu.h At the moment we have each SoC's memory map defined in its own cpu.h, which is included in include/configs/sunxi_common.h. This will be a problem with the introduction of Allwinner RISC-V support. Remove the inclusion of that header file from the common config header, instead move the required serial base addresses (for the SPL) into a separate header file. Then include the original cpu.h file only where we really need it, which is only under arch/arm now. This disentangles the architecture specific header files from the generic code.

sunxi: introduce NCAT2 generation model Allwinner seems to typically stick to a common MMIO memory map for several SoCs, but from time to time does some breaking changes, which also introduce new generations of some peripherals. The last time this happened with the H6, which apart from re-organising the base addresses also changed the clock controller significantly. We added a CONFIG_SUN50I_GEN_H6 symbol back then to mark SoCs sharing those traits. Now the Allwinner D1 changes the memory map again, and also extends the pincontroller, among other peripherals. To mark this generation of SoCs, add a CONFIG_SUNXI_GEN_NCAT2 symbol, this name is reportedly used in the Allwinner BSP code, and prevents us from inventing our own name. Add this new symbol to some guards that were already checking for the H6 generation, since many features are shared between the two (like the renovated clock controller). This paves the way to introduce a first user of this generation. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Tested-by: Samuel Holland <samuel@sholland.org>
