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: sun6i: Add support for the power reset control module found on the A31 The A31 has a new module called PRCM, or Power, Reset Control Module. This module controls clocks and resets for RTC block modules, and also PLL biasing in the main clock module. This patch adds the register definitions, and also enables the clocks and resets for the RTC block PIO (pin controller) and P2WI (push-pull 2 wire interface) which is used to talk to the PMIC.

sunxi: prcm: Add memory map for H6 like SoCs There was no need to have prcm definitions for H6 and similar SoCs till now. However, support R_I2C will be needed soon in SPL. Move old definitions to prcm_sun6i.h and add new ones in prcm_sun50i.h. One of those files will be selected in common prcm.h based on defined macros. This commit doesn't do any functional change.

/* prcm regs definition */
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>
