From bf0045f2dddbc9f3e75b3bcfecfdb04aea39a596 Mon Sep 17 00:00:00 2001 From: Janne Grunau Date: Mon, 13 Mar 2023 14:54:32 +0100 Subject: [PATCH] apple_m1_defconfig: Bump CONFIG_LMB_MAX_REGIONS to 64 Apple silicon SoCs have numerous embedded co-processors with pre-loaded firmware. The co-processors text and data sections need to be mapped via DART iommus controlled by the main processor. Those sections are exported as reserved-memory. Bump CONFIG_LMB_MAX_REGIONS from 8 to 64 to deal with the large amount of reserved-memory regions.
