Subject: [PATCH 089/113] mtd: spi-nor: fsl-quadspi: add support for
 layerscape

[context adjustment]

LS1043a and LS2080A in the Layerscape family also support Freescale Quad
SPI, make Quad SPI selectable for these hardwares.

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.
