Allwinner SoCs can remap some bits of peripheral SRAM to a contiguous range of addresses for use by early boot software. Usually the video engine's SRAM is used for this purpose, so its mapping must be switched back before the hardware can be used. However, the D1 and related SoCs use the DSP SRAM for this purpose. As a result, the video engine SRAM is not switchable, and there is no need for an allwinner,sram reference in the devicetree.
