Subject: [PATCH] ARM64: dts: meson-gx: fix ATF reserved memory region
Date: Thu, 7 Jun 2018 13:55:14 -0700 [thread overview]
Message-ID: <20180607205514.36631-1-khilman@baylibre.com> (raw)
Vendor firmware/uboot has different reserved regions depending on
firmware version, but current codebase reserves the same regions on
GXL and GXBB, so move the additional reserved memory region to common
.dtsi.
Found when putting a recent vendor u-boot on meson-gxbb-p200.
