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: Introduce common symbol for H6 like SoCs It turns out that there are at least 2 other SoCs which have basically the same memory map, similar clocks and other features as H6. It's very likely that we'll see more such SoCs in the future. In order to ease porting to new SoCs and lower ifdef clutter, introduce common symbol for them.

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>

sunxi: make V3s DRAM initialization more proper Previously, because we have no source code about the DRAM initialization of V3s and missing some configurations (delays and MBUS QoS info), our V3s DRAM initialization sequence is hacked from the H3 one. As the SDK shipped with PineCube contains source code for V3s libdram, we can retrieve these information from it and tweak some other magic bits.

sunxi: DRAM: add Allwinner H5 support The DRAM controller in the Allwinner H5 SoC is again very similar to the one in the H3 and A64. Based on the existing socid parameter, add support for this controller by reusing the bulk of the code and only deviating where needed. These new bits set or cleared here and there have been mostly found by looking at DRAM register dumps after using the H5 boot0 and comparing them to what we set in the code. So for now it's mostly unclear what those bits actually mean - hence the missing names and comments. Also add the delay line parameters taken from the boot0 and libdram disassembly. Register setup differences between H5 and H3 are courtesy of Jens Kuske. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com>
