Subject: [PATCH RFC 02/18] ARM: bcm2835: DMA can only address 1GB
Date: Wed, 17 Jul 2019 21:50:10 +0200 [thread overview]
Message-ID: <1563393026-17118-3-git-send-email-wahrenst@gmx.net> (raw)
In-Reply-To: <1563393026-17118-1-git-send-email-wahrenst@gmx.net>
From: Phil Elwell <phil@raspberrypi.org>
The legacy peripherals can only address the first gigabyte of RAM, so
ensure that DMA allocations are restricted to that region.
