[yocto] Porting of specific Kernel/Driver into yocto.

[Om Prakash PAL]

Hi Gary,
Please find the attached log.
In bootargs, you can check it 'console=ttyAMA2'

Best Regards,

Note: if you (Om Prakash PAL) could send the entire boot log, we could make more
sense of your issues.  For example, the actual name(s) of serial devices supported
by the kernel will be listed there.

Also, I seem to recall that you had 'console=tty0' in your bootargs.

Send the complete log...
