   4 Subject: [PATCH] dts: bcm2711: add "High Peripheral" mode overlay
   5
   6 The following addresses change:
   7
   8  - 0xfc00_0000 -> 0x4_7c00_0000
   9  - 0xff80_0000 -> 0x4_c000_0000
  10
  11 The range 0xfc00_0000-0xffff_ffff becomes available as system RAM on
  12 devices with >= 4 GiB of RAM. Firmware should initialize the memory node
  13 appropriately.
