Hi Walter,

Can we use "kind" and "version" attribute of a sopcinfo file to build
the match string? This way, your dts converter won't need update for
each new component.

eg,

kind="altera_avalon_spi" version="9.0" ==> "altera","avalon-spi-9.0"

kind="altera_up_avalon_ps2_classic" version="6.1" ==>
"altera","up-avalon-ps2-classic-6.1"
