When using recent udev, the /dev node mount requires CONFIG_DEVTMPFS_MOUNT
is enabled in Kernel. The patch enables the option in defconfig of Freescale
QorIQ targets.
Changed defconfig list:
arch/powerpc/configs/85xx/p1023rds_defconfig
arch/powerpc/configs/corenet32_smp_defconfig
arch/powerpc/configs/corenet64_smp_defconfig
arch/powerpc/configs/mpc85xx_smp_defconfig

Really?
I know it makes life easier when you don't have an initramfs, but is it
actually required now?
cheers

[Luo Zhenhua-B19537] I didn't use initramfs when the issue is found, I thin=

Yes, it is required to get udev to work properly (versions of udev
newer than ~173)

What about mpc83xx and mpc85xx (non-smp)?
It'd be nice if non-hardware-specific things that are required for a
typical Linux system were "default y". Even nicer if we could have
config fragments for various usage profiles that are separate from
hardware config.

Applied with mpc85xx_defconfig and mpc83xx_defconfig added.
