Hi Jassi,

With the next update the PandaBoard 4430 is working fine.
cpu_is_omap4430() macro is not define. We should use cpu_is_omap443x()
macro in order to select correctly PandaBoard and not PandaBoardES
board. Due to this error the heaset Mic pin is not enable so record is not
working (use for Panda 4430 recording).
