  11. Other addresses are either reserved, or not used directly by u-boot.

  13. Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
  14. -------------------------------------------------------------------
  15. One needs to use appropriate bootargs to boot Linux flavors which do
  16. not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
  17. below:
  18. => setenv bootargs 'console=ttyS1,115200 root=/dev/ram
  19. earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
  20. hugepages=16 mem=2048M'
