Subject: [U-Boot] [PATCH v6 3/6] ls2080ardb: Reserve DP-DDR RAM
Date: Wed, 19 Oct 2016 16:31:14 +0200 [thread overview]
Message-ID: <1476887477-189387-4-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1476887477-189387-1-git-send-email-agraf@suse.de>
The DP-DDR shouldn't be exposed as conventional memory to an OS, so let's
rather claim it's a reserved region in the EFI memory map
