Subject: [PATCH RFC 05/18] ARM: dts: bcm283x: Define memory at board level
Date: Wed, 17 Jul 2019 21:50:13 +0200
Message-ID: <1563393026-17118-6-git-send-email-wahrenst@gmx.net> (raw)
In-Reply-To: <1563393026-17118-1-git-send-email-wahrenst@gmx.net>

Now with the varity of several RPi boards, the memory should be defined
at board level. This step gives us the chance to fix the memory size
of the RPi 1 B+, Zero (incl. W) and Compute Module 1.
