[meta-ti] OMAP5: Booting build output

[Ian Wisbon]

Chase,

For some reason, basic arithmetic and counting from zero escaped me
today.

You are of course, correct, as the 4 port enumerates ttyUSB0-3, and the
uEVM, then creates ttyUSB4 and ttyUSB5 - ttyUSB4 being the correct dev
entry. That's what I get for not looking at dmesg, and, counting. Thank
you sir. It does, in fact, load the bootloaders.

I appreciate your time, and, hopefully this will serve to help others -
sorry for the bother!

Cheers,

Ian
