  34 Similar to MT7981 and MT7986 also MT7988 can have a high number of
  35 reserved-memory regions used by the various hardware offloading
  36 subsystems.
  37
  38 Raise CONFIG_LMB_MAX_REGIONS to 64 to avoid errors when trying to boot
  39 Linux with more then 6 reserved regions:
  40
  41 ERROR: reserving fdt memory region failed (addr=4f700000 size=240000 flags=4)
  42 ERROR: reserving fdt memory region failed (addr=15194000 size=1000 flags=4)
