126Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
127-------------------------------------------------------------------
128One needs to use appropriate bootargs to boot Linux flavors which do
129not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
130below:
131
132=> setenv bootargs 'console=ttyS1,115200 root=/dev/ram
133 earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
134 hugepages=16 mem=2048M'
