Hi Sourav, Felipe,
any progress on fixing the N800 problem? Would be good to keep it booting
since we use it as our primary 2420 test platform.

The patch sent inlined below might help us to get rid of the serial init
issue.
Unfortunately, I dont have a N800 board with me to test it and will require
your help to do so.

Subject: [RFT/PATCH] serial: omap: Fix N800 serial init issue.
This patch might solve the N800 serial init issue.
This patch will also give pointers if there is any mux settings issue
with N800 OR
a mismatch between the initial harware state, runtime PM state and omap
hwmod state.
I don't have a N800 schematics to check about the mux settings getting used.
The observation on beagle board XM with this patch on different boards
looks flaky,
so your feedback on beagle board will also be very helpful.
