[PATCH v2 10/15] arm64: dts: allwinner: a64: Add support for the SRAM C1 section

From: Paul Kocialkowski <hidden>
Date: 2018-12-05 09:25:53
Also in: linux-arm-kernel, linux-media, lkml
Subsystem: arm/allwinner sunxi soc support, the rest · Maintainers: Chen-Yu Tsai, Jernej Skrabec, Samuel Holland, Linus Torvalds

Add the description for the SRAM C1 section to the A64 device-tree.

Since there is no entry for this section in the A64 manual, the base
address and size were only verified to be consistent empirically.

Signed-off-by: Paul Kocialkowski <redacted>
