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 67/93] armv8: ls1012a: DDR optmizations
Enable DDR row-bank-column decoding. DDR address will
be decoded as row-bank-column instead of bank-row-column.
This will improve performance of serial data transfers.
Refresh cycle value must be selected based on the frequency
of DDR. tREFI = 7.8 us as per JEDEC. The value for MDREF[REF_CNT]
should be based on round up (tREFI/tCK) formula. For 500MHz, mdref
value should be 0x0f3c8000.
