From: Claudiu Beznea Date: Wed, 2 Dec 2020 09:57:05 +0000 (+0200) Subject: ARM: dts: at91: sama5d2: map securam as device X-Git-Tag: microblaze-v5.12~94^2~21^2~1 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=9b5dcc8d427e2bcb84c49eb03ffefe11e7537a55;p=linux-2.6-microblaze.git ARM: dts: at91: sama5d2: map securam as device Due to strobe signal not being propagated from CPU to securam the securam needs to be mapped as device or strongly ordered memory to work properly. Otherwise, updating to one offset may affect the adjacent locations in securam.
