But the kernel command line as set up by linaro-media-create has
console=ttyO2 for panda.
That's correct - you need to use ttyS2 if you do not have
CONFIG_SERIAL_OMAP enabled - this option was introduced along with the
the new omap-serial driver that was merged in mainline only in the .37
merge window.
I haven't back ported this driver - if someone feels it's useful, it
should be trivial to cherry-pick these patches. (ISTR it was a series of
around 7 patches, and then there were a couple of fixes on top).
The consequence to end users of enabling this driver is that all OMAP
on-SoC serial ports will be owned by this driver and will use ttyOx, and
not-on-SoC ports (like on the zooms) will use ttySx as before (although
they will be renumbered). Benefits include DMA support
I did not think this qualified as a fix for the .35 kernel, so I did not
pick it up. Let me know if it should be.
