This series introduces support for the Allwinner A523 SoC family. The same die is used in different packages: the A523, A527, T527, and H728: they connect a different set of peripherals to the pins, or enable extra goodies like an NPU. From a U-Boot perspective those chips do not differ much, all the differences are described in the board DT files. These patches are not the most refined at the moment, but I hope that people start reviewing them, so we can merge the ones that are ready, to reduce their number.
To be able to share the SPL clock code, the existing H6 code gets refactored in patches 01-13. This removes the C struct describing the 127 clock registers, and replaces it with macros defining the register offsets. For more rationale and explanation see the 01/34 commit message. Patches 14-20 extend the existing Allwinner U-Boot drivers to cope with some of the changed peripherals, this includes the mandatory clock and pinctrl drivers, but also some clock tweaks for the MMC controller driver, and support for the new watchdog and the AXP323 used. Patches 21-23 update some SPL bits to be able to cope with the A523. Patches 24-28 extend the FEL handling code: the A523 has a GICv3, which requires saving some GICv3 system registers, plus the IRQ mode stack pointer. Patches 25-27 refactor the CPU clock code, and add the new clock bits required by the A523. Patch 29-32 add the new SPL bits for the A523, most prominently the DRAM initialisation code. Many thanks to Jernej and Mikhail for providing this part, there is a great reverse engineering and testing effort behind this. Patch 33 copies the DT files from the proposed Linux patches. They have not been merged yet, mostly due to one missing DT binding dependency in the linux-next tree, but have otherwise been agreed upon, with almost every used binding being already merged. Eventually we will use the copy from the DT rebasing repo, but for now those files must do. The final patch adds defconfig files for the three boards that seem to be the most popular at the moment, they include two development boards and one TV box. The most interesting bits in there are the DRAM parameters. Please have a look, review, and test. Thanks!
