Hi Kishore

one can try approach described on

Patch to support uboot logo keep from uboot to kernel to Android for JB4.2.2_1.1.0-GA and L3.0.35_4....

though I am not aware of similar patch for i.MX23.

Other option move lcd initialization to kernel phase, making bootloader as short as

possible.

Best regards

igor
