Set SERIAL_CONSOLES if you want to define multiple serial consoles, also if
you need to check for the presence of the serial consoles you can also define
SERIAL_CONSOLES_CHECK to determine if these are present when you boot. This
will prevent error message that pop up when the serial port is not present.
SERIAL_CONSOLES = "115200;ttyS0 115200;ttyS1 115200;ttyEHV0"
SERIAL_CONSOLES_CHECK = "${SERIAL_CONSOLES}"
The above lines in machine.conf or elsewhere will have the effect of having
two serial consoles and removing any that are not present at boot

Poky
Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "") and contains only emulated machine support.
