Hi Matt,

as you are already working with the configs, please have a look at this 
as well (NOT a regression of your series):

$ jailhouse config check -a arm64 configs/arm64/k3-am654-idk.cell 
Reading configuration set:
  Root cell:     k3-am654-idk (configs/arm64/k3-am654-idk.cell)
Overlapping memory regions inside cell:

  size:       0x0000000003ac3000
  flags:      JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE | JAILHOUSE_MEM_IO
physically and virtually overlaps with region 15
