Subject: [U-Boot] [PATCH v5 11/30] arm64: Only allow dcache disabled in SPL builds
Date: Fri, 4 Mar 2016 01:09:55 +0100 [thread overview]
Message-ID: <1457050214-117592-12-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1457050214-117592-1-git-send-email-agraf@suse.de>
Now that we have an easy way to describe memory regions and enable the MMU,
there really shouldn't be anything holding people back from running with
caches enabled on AArch64. To make sure people catch early if they're missing
on the caching fun, give them a compile error.
