Re: [PATCH] [linux-devel]arm64: Add DTS support for FSL's LS1012A SoC

The QorIQ LS1012A processor is a new Freescale' SoC optimized
for battery-backed or USB-powered, integrates a single ARM
Cortex-A53 core with a hardware packet forwarding engine
and high-speed interfaces to deliver line-rate networking performance.
LS1012AQDS, LS1012ARDB, LS1012AFRDM are a high-performance development platform
using LS1012A SoC.

Add the device tree support for FSL LS1012A SoC.
Following levels of DTSI/DTS files have been created for the LS1012A
SoC family:

        - fsl-ls1012a.dtsi:
                DTS-Include file for FSL LS1012A SoC.

        - fsl-ls1012a-frdm.dts:
                DTS file for FSL LS1012A FRDM board.

        - fsl-ls1012a-qds.dts:
                DTS file for FSL LS1012A QDS board.

        - fsl-ls1012a-rdb.dts:
                DTS file for FSL LS1012A RDB board.

Add ls1012ardb, ls1012aqds and ls1012afrdm dtb in Makefile
