| 126 | Booting Linux flavors which do not support 48-bit VA (< Linux 3.18) |
| 127 | ------------------------------------------------------------------- |
| 128 | One needs to use appropriate bootargs to boot Linux flavors which do |
| 129 | not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown |
| 130 | below: |
| 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' |
