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 113/113] mtd: spi-nor: fsl-quad: move mtd_device_register to
|
|
the last of probe
|
|
|
|
After call mtd_device_register, the mtd devices should be workable immediately.
|
|
If before finish all of init work call the mtd_device_register, it will not
|
|
respond work request timely.
|
|
|
|
For example, openwrt/lede have a AUTO split special flash partitions mechanism
|
|
while mtd driver register. So, before call mtd_device_register, must let all of
|
|
init work ready.
