We are porting 3.10 kernel for our custom board based on imx6sl.
In imx6sl.dtsi file, It is shown that driver is compatible with "fsl,imx28-lcdif", so we are enabling it to bringup the display.
when we enable "MXS LCD framebuffer support" to bringup the display, the kernel stops in between(Please see the below log)
Memory: 447MB 64MB = 511MB total
Memory: 243392k/243392k available, 280896k reserved, 0K highmem

SLUB: HWalign=64, Order=0-3, MinObjects=0, CPUs=1, Nodes=1
Preemptible hierarchical RCU implementation.
RCU restricting CPUs from NR_CPUS=4 to nr_cpu_ids=1.

L310 cache controller enabled
l2x0: 16 ways, CACHE_ID 0x410000c8, AUX_CTRL 0x32030000, Cache size: 262144 B
But when we disable the "Support for frame buffer devices" option in device drivers --> graphics, we are able to successfully boot the system.(without display)
We are using following:
bootargs:
setenv bootargs console=ttymxc2,115200 init=/init androidboot.console=ttymxc2 consoleblank=0 androidboot.hardware=freescale
dts:
imx6sl-evk-ldo.dts
Please let us know what we are missing. Thanks in advance
