From 8d14f8e898b4cd4d9ff76b6afcbaf25bf37aa1e7 Mon Sep 17 00:00:00 2001 From: Michael Riesch Date: Wed, 10 Nov 2021 11:45:30 +0100 Subject: arm: rockchip: add support for the quartz64 board The Pine64 Quartz64 board features the Rockchip RK3566, a reduced but largely identical version of the RK3568. Two models (A and B) of the Quartz64 board are envisaged, where this patch targets the already available model A.
