[PATCH] arm64: dts: qcom: qcm6490-fairphone-fp5: Add missing reserved-memory

Posted by Luca Weiss 1 year, 12 months ago

It seems we also need to reserve a region of 81 MiB called "removed_mem"
otherwise we can easily hit the following error with higher RAM usage:

  [ 1467.809274] Internal error: synchronous external abort: 0000000096000010 [#2] SMP
