This series of patches base on the latest branch/master, and add support for the StarFive JH7110 RISC-V SoC and VisionFive V2 board. In order for this to be achieved, the respective DT nodes have been added, and the required defconfigs have been added to the boards' defconfig. What is more, the basic required DM drivers have been added, such as reset, clock, pinctrl, uart, ram etc.
Note that the register base address of reset controller is same with the clock controller. Therefore, there is no device tree node alone for reset driver. It binds device node in the clock driver.
The u-boot-spl and u-boot has been tested on the VisionFive V2 boards which equip with JH7110 SoC and works normally.
For more information and support, you can visit RVspace wiki[1].
Changes in v2: - Renamed file 'jh7110-regs.h' to 'regs.h'. - Reworded the clear L2 LIM memory code in C. - Removed flash init call in 'spl_soc_init' function. - Reworded the clock driver. - Rename the macro 'SET_DIV' to 'ASSIGNED_CLOCK_PARENTS' in 'spl.c'. - Moved the device tree node 'dmc@15700000' from 'jh7110-u-boot.dtsi' to 'starfive_visionfive2-u-boot.dtsi'.
