[yocto] Quick question about TTY ports

[Paul D. DeRocco]

I'm using the cedartrail (Atom) BSP, which supports motherboards with two
standard serial ports. If I run Ubuntu on one of these mobos, I get
/dev/ttyS0 and /dev/ttyS1. When I build the cedartrail image, I get
/dev/ttyS0 and /dev/ttySA0. Is ttySA0 the second serial port, or something
else? A Google search shows that this ttySA nomenclature is occasionally
used in various systems, but nowhere can I find any info on what it
conventionally means.
