     18 Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
     19 -------------------------------------------------------------------
     20 One needs to use appropriate bootargs to boot Linux flavors which do
     21 not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
     22 below:
     23 
     24 => setenv bootargs 'console=ttyS1,115200 root=/dev/ram
     25    earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
     26    hugepages=16 mem=2048M'
