Add support for NXP layerscape ls1043ardb 64b/32b Dev board. LS1043a is an SoC with 4x64-bit up to 1.6 GHz ARMv8 A53 cores. ls1043ardb support features as: 2GB DDR4, 128MB NOR/512MB NAND, USB3.0, eSDHC, I2C, GPIO, PCIe/Mini-PCIe, 6x1G/1x10G network port, etc. 64b/32b ls1043ardb target is using 4.4 kernel, and rcw/u-boot/fman images from NXP QorIQ SDK release. All of 4.4 kernel patches porting from SDK release or upstream. QorIQ SDK ISOs can be downloaded from this location: http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-processors:SDKLINUX Signed-off-by: Yutang Jiang <yutang.jiang@nxp.com>
