Subject: [PATCH 0/7] ARM: NOMMU: MPU updates
Date: Fri, 7 Jul 2017 11:39:52 +0100 [thread overview]
Message-ID: <9fb560aa-59a7-9138-3b02-235c79d1fc33@arm.com> (raw)
In-Reply-To: <003cd30f-b39f-c930-ab75-298333c2fa29@arm.com>
Hi,
I know, we are in a middle of the merge window, but given that DMA fixes for
NOMMU have landed in Linus tree it'd be handy to have this patch set included
too:
"These MPU patches introduce a nice feature that it simplifies the bootloader:
do not need to setup the MPU, for example for coherent DMA region, which is
described in device-tree too." Andr?s Szemz?
Thanks!
Vladimir
