From 3a49b50a7fdd12679c5c9b1fd2fc8ae2fb9269df Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Wed, 2 Dec 2020 11:57:05 +0200 Subject: [PATCH] ARM: dts: at91: sama5d2: map securam as device [ Upstream commit 9b5dcc8d427e2bcb84c49eb03ffefe11e7537a55 ] 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.
