From 239fec2497907f2adf7e6b9fdda4138e81bac619 Mon Sep 17 00:00:00 2001 From: BALATON Zoltan Date: Thu, 14 Oct 2021 21:50:19 +0200 Subject: [PATCH] ppc/pegasos2: Restrict memory to 2 gigabytes The CHRP spec this board confirms to only allows 2 GiB of system memory below 4 GiB as the high 2 GiB is allocated to IO and system resources. To avoid problems with memory overlapping these areas restrict RAM to 2 GiB similar to mac_newworld.
