Yogesh Gaur 70a131eb5a board/ls2080a, ls1088a: Add check for mc-dpl applied in fdt 
Function fdt_fixup_board_enet() performs fdt fixup. Only return
fdt_status_okay() when both MC is applied and DPL is deployed, else
return fdt_status_fail().

This check is added to LS1088A/LS2080A/LS2088A boards.

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'
