From: Neil Armstrong <narmstrong@baylibre.com>
[ Upstream commit bba8e3f42736cf7f974968a818e53b128286ad1d ]
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.
Fixes: 4f24eda8401f ("ARM64: dts: Prepare configs for Amlogic Meson GXBaby")
