Chaithrika, I noticed this too, though with CONFIG_DEBUG_LL, I see garbage on my serial console. If you checkout at this commit: 6c76c1971a42eb96448c10f914e444e35049cdcd, dm6467 boots again. Checking out the next commit, which is a merge with upstream, it no longer works for me. A quick look a the diff between the two commits, I didn't see anything obvious changing in DaVinci specific code. I don't have a working CCS for this platform, but if you have a working CCS, it might be worth debugging where the code actually is. On quick way is to just dump the kernel printk log. Look for the address of the symbol __log_buf in System.map. Then using CCS, halt the kernel and dump memory at that location in ASCII. You should then see the kernel printk messages.
