There are two LS series processors are built on ARMv8 Layersacpe architecture currently, LS2085A and LS1043A. They are based on ARMv8 core although use different chassis, so create fsl-layerscape to refactor the common code for the LS series processors which also paves the way for adding LS1043A platform.

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'
