This driver requests and remaps a memory region as configured in the device tree. It serves memory from this region via the genalloc API. It optionally enables the SRAM clock. Other drivers can retrieve the genalloc pool from a phandle pointing to this drivers' device node in the device tree. The allocation granularity is hard-coded to 32 bytes for now, to make the SRAM driver useful for the 6502 remoteproc driver. There is overhead for bigger SRAMs, where only a much coarser allocation granularity is needed: At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap to track allocations.
