[PATCH v3 05/14] ARM: sun5i: Add support for the C1 SRAM region with the SRAM controller

From: Paul Kocialkowski
Date: Mon May 07 2018 - 08:48:02 EST


From: Maxime Ripard <maxime.ripard@xxxxxxxxxxx>

This adds support for the C1 SRAM region (to be used with the SRAM
controller driver) for sun5i-based platforms. The region is shared
between the Video Engine and the CPU.
