In the DT this is described with the target-supply property in the AHCI DT node, pointing to a (GPIO controlled) regulator. Since we need SATA only in U-Boot proper, and use a DM driver for AHCI there, we should use the DT instead of hardcoding this. Add code to the sunxi AHCI driver to check the DT for that regulator and enable it, at probe time. Then drop the current code from board.c, which was doing that job before. This allows us to remove the SATAPWR Kconfig definition and the respective values from the defconfigs. We also select the generic fixed regulator driver, which handles those GPIO controlled regulators. Please note that the OrangePi Plus is a bit special here, it's a H3 board without native SATA, but with a USB-to-SATA bridge. The DT models the SATA power via a VBUS supply regulator, which we don't parse yet in the USB PHY driver. Use the hardcoded CONFIG_USB3_VBUS_PIN for that board meanwhile.

As we want to get rid of those, we need to find the regulator by chasing up the DT. The sun4i-emac binding puts the PHY regulator into the MDIO node, which is the parent of the PHY device. U-Boot does not have (and does not need) an MDIO driver, so we need to chase down the regulator through the EMAC node: we follow the "phy-handle" property to find the PHY node, then go up to its parent, where we find the "phy-supply" link to the regulator. Let U-Boot find the associated regulator device, and put that into the private device struct, so we can find and enable the regulator at probe time, later.

In the DT this is described with the phy-supply property in the MAC DT node, pointing to a (GPIO controlled) regulator. Since we need Ethernet only in U-Boot proper, and use a DM driver there, we should use the DT instead of hardcoding this. Add code to the sun8i_emac and sunxi_emac drivers to check the DT for that regulator and enable it, at probe time. Then drop the current code from board.c, which was doing that job before. This allows us to remove the MACPWR Kconfig definition and the respective values from the defconfigs.

However the D1 and successors use a slightly different pinctrl register layout. Use that opportunity to drop "struct sunxi_gpio", that described that MMIO frame in a C struct. That approach is somewhat frowned upon in the Linux world and rarely used there, though still popular with U-Boot. Switching from a C struct to a "base address plus offset" approach allows to switch between the two models more dynamically, without reverting to preprocessor macros and #ifdef's. Model the pinctrl MMIO register frame in the usual "base address + offset" way, and replace a hard-to-parse CPP macro with a more readable static function. All the users get converted over. There are no functional changes at this point, it just prepares the stages for the D1 and friends.

This should not be needed in a DM world anymore, since the generic GPIO framework handles that nicely. For Allwinner boards we still need to deal with non-DM GPIO in the SPL, but this should become the exception, not the rule. Make this more obvious by removing the definition of GPIO_EXTRA_HEADER, and just force every legacy user of platform specific GPIO to include the new sunxi_gpio.h header explicitly. Everyone doing so should feel ashamed and should find a way to avoid it from now on.

In the old days that was used by every driver, but nowadays it should only be needed by SPL drivers (not using the DT). Many addresses in there were never used, and some are not needed anymore. To avoid a dependency on CPU specific headers in an arch specific directory, move the definition of the pinctroller MMIO base address into the sunxi_gpio.h header, because the SPL routines for GPIO should be the only one needing this address. This is a first step towards getting rid of cpu_sun[x]i.h completely, and allows to remove the inclusion of that file from the sunxi_gpio.h header.

Ideally this would all be handled by devicetree and DM drivers, but for the DT-less SPL we still need the legacy interfaces. Add a new Kconfig symbol to differenciate between the two generations of pincontrollers, and just use that to just switch some basic symbols. The rest is already abstracted enough, so works out of the box.

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.

The R528/T113-s SoC (with ARM cores) and the D1/D1s Soc (with RISC-V cores) share the same die, so should share the same DRAM init routines as well. To prepare for this, add a new sunxi directory inside drivers/ram, and add some stub entries to prepare for the addition of the share DRAM code for those SoCs. The RISC-V D1(s) SoCs will probably use SPL_DM, so for that SoC this would be the right directory anyway.

Make use of prior art here and lift some code from awboot[1], which carried init code based on earlier decompilation efforts, but with a GPL2 license tag. This code has been heavily reworked and cleaned up, to match previous DRAM routines for other SoCs, and also to be closer to U-Boot's coding style and support routines. The actual DRAM chip timing parameters are included in the main file, since they cover all DRAM types, and are protected by a new Kconfig CONFIG_SUNXI_DRAM_TYPE symbol, which allows the compiler to pick only the relevant settings, at build time. The relevant DRAM chips/board specific configuration parameters are delivered via Kconfig, so this code here should work for all supported SoCs and DRAM chips combinations.

This was introduced with the RISC-V based Allwinner D1 SoC, which actually shares a die with the ARM cores versions called R528 (BGA, without DRAM) and T113s (QFP, with embedded DRAM). This adds the new Kconfig stanza, using the two newly introduced symbols for the new SoC generation and pincontroller. It also adds the new symbols to the relavent code places, to set all the hardcoded bits directly. We need one DT override: The ARM core version of the DT specifies the CPUX watchdog as "reserved", which means it won't be recognised by U-Boot. Override this in our generic sunxi-u-boot.dtsi, to let U-Boot pick up this watchdog, so that the generic reset driver will work.

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.

(IS_ENABLED(...))` to make the optimizer include only the appropriate function bodies instead. There are no functional changes here.

This patch moves away from using the structs `sunxi_cpucfg_reg` and `sunxi_prcm_reg` in psci.c. The former struct and its associated header file existed only to support PSCI code, so also delete them altogether.
