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