ARM64: dts: meson-gx: Add firmware reserved memory zones
The Amlogic Meson GXBB/GXL/GXM secure monitor uses part of the memory space, this patch adds these reserved zones. Without such reserved memory zones, running the following stress command : $ stress-ng --vm 16 --vm-bytes 128M --timeout 10s multiple times: Could lead to the following kernel crashes : [ 46.937975] Bad mode in Error handler detected on CPU1, code 0xbf000000 -- SError ... [ 47.058536] Internal error: Attempting to execute userspace memory: 8600000f [#3] PREEMPT SMP ... Instead of the OOM killer.
