The SRAM mapping controls on Allwinner SoCs is located in a block called "System Controls". This block also has registers for identifying the SoC, reading the state of an external boot-related pin, and on some newer SoCs, glue layer controls for the EMAC Ethernet controller. The A64 variant compatible is renamed to "allwinner,a64-system-control" to reflect this. The old A64 compatible is deprecated. So far we haven't seen any actual use of it.
