From cf4eba4eb66dbf6102200af6ba6f1ee05fabfe3d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pali=20Roh=C3=A1r?= Date: Fri, 9 Sep 2022 17:32:42 +0200 Subject: [PATCH] ddr: fsl: Fix checking for maximal mappable memory MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Check needs to be done against CONFIG_MAX_MEM_MAPPED macro and not fixed size 4GB (as CONFIG_MAX_MEM_MAPPED can be lower and for example for e500 cores it is just 2GB). Also fix printf re-align, which should be applied only for non-SPL builds, during init_dram() call.
