Priyanka Jain 9ae836cde7 armv8: fsl-layerscape: Add NXP LS2088A SoC support
The QorIQ LS2088A SoC is built on layerscape architecture.

It is similar to LS2080A SoC with some differences like
1)Timer controller offset is different
2)It has A72 cores
3)It supports TZASC module

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'
