2018-09-12dt-bindings: sunxi-sram: add binding for Allwinner H6 SRAM CIcenowy Zheng1-0/+4
The Allwinner H6 SoC's DE3 needs the SRAM C section being claimed in the system controller to work, like A64 DE2. As H6 and A64 system controller are quite similar, code is reused now, and the A64 fallback compatible string is added after the H6 compatible string.

2018-09-12drivers: soc: Allow building the sunxi driver without ARCH_SUNXIPaul Kocialkowski1-1/+1
This makes it possible to build the sunxi SRAM driver without building for the sunxi architecture. This allows selecting the driver when building the kernel in testing environments. In particular, this is necessary for testing of the Cedrus driver, that selects the sunxi SRAM driver.
