[meta-freescale] Problems about selecting linux kernel drivers.

[Yusuf Altıparmak]

Apologies for the situation, this was my first question to community.

I didn't know the differences between built-ins and modules. I made a
little research after your answer and corrected the defconfig file as you
explained in last answer. Everything gone well. kernelmodules.tar file is
changed with including the desired drivers.
