[meta-freescale] branch fido couldn't boot mx6q sabreSD board

[Wally Yeh]

Hi, guys:
    recently I wanna test latest yocto bsp to see if it fix the mouse
cursor blink during screen refresh. but I found I even couldn't get it
boot into system.

   The only modification is just set it soft-fp by appending
DEFAULTTUNE_mx6 = "cortexa9-neon", my local.conf:

MACHINE ??= 'imx6qsabresd'
DISTRO ?= 'poky'
PACKAGE_CLASSES ?= "package_rpm"
EXTRA_IMAGE_FEATURES = "debug-tweaks"
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
PATCHRESOLVE = "noop"
BB_DISKMON_DIRS = "\
    STOPTASKS,${TMPDIR},1G,100K \
    STOPTASKS,${DL_DIR},1G,100K \
    STOPTASKS,${SSTATE_DIR},1G,100K \
    ABORT,${TMPDIR},100M,1K \
    ABORT,${DL_DIR},100M,1K \
    ABORT,${SSTATE_DIR},100M,1K"
PACKAGECONFIG_append_pn-qemu-native = " sdl"
PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"
ASSUME_PROVIDED += "libsdl-native"
CONF_VERSION = "1"
DEFAULTTUNE_mx6 = "cortexa9-neon"

BB_NUMBER_THREADS = '4'
PARALLEL_MAKE = '-j 4'

DL_DIR ?= "${BSPDIR}/downloads/"
ACCEPT_FSL_EULA = "1"
/******** local.conf end ********/

    The boot log, shows it got stuck on starting kernel:

    If there is any setting I miss please give me a hint, thanks.
