Yutang Jiang 15a14cf166 layerscape: add 64b/32b target for ls1012ardb device
The QorIQ LS1012A processor, 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.
QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance
development platform, with a complete debugging environment.
The LS1012ARDB board supports the QorIQ LS1012A processor and is
optimized to support the high-bandwidth DDR3L memory and
a full complement of high-speed SerDes ports.

LEDE/OPENWRT will auto strip executable program file while make. So we
need select CONFIG_NO_STRIP=y while make menuconfig to avoid the ppfe network
fiemware be destroyed, then run make to build ls1012ardb firmware.

The fsl-quadspi flash with jffs2 fs is unstable and arise some failed message.
This issue have noticed the IP owner for investigate, hope he can solve it
earlier. So the ls1012ardb now also provide a xx-firmware.ext4.bin as default
firmware, and the uboot bootcmd will run wrtboot_ext4rfs for "rootfstype=ext4"
bootargs.

Subject: [PATCH 077/113] mtd: add get/set of_node/flash_node helpers
We are going to begin using the mtd->dev.of_node field for MTD device
nodes, so let's add helpers for it. Also, we'll be making some
conversions on spi_nor (and nand_chip eventually) too, so get that ready
with their own helpers.
commit:28b8b26b308e656edfa9467867d5f79212da2ec3
delete the include/linux/mtd/nand.h
just upgrade the code about spi.
