From 37e83250e83ee00e884d38a76a5e94c91ab28d05 Mon Sep 17 00:00:00 2001 From: Yidi Lin Date: Thu, 1 Jun 2023 12:15:17 +0800 Subject: soc/mediatek/common: Disable DRAM scramble by default Geralt SoC does not support 'persist certain regions' across reboots. Considering the impact of missing ramoops for debugging, set MEDIATEK_DRAM_SCRAMBLE to default n to disable this feature in production FW image.
