Nicolas,

Your understanding is correct. As a matter of fact, we pushed the support for 
SOC_FAMILY used in overrides and COMPATIBLE_MACHINE into OE/Bitbake some time 
ago, so you can now target the range of platforms based on the same SoC.

You can do things like:

VAR_omap4 = "VAL"

As well as:

COMPATIBLE_MACHINE = "omap4"

Please note, the latter one takes regular expression, so you can do 
"omap4|omap5" or even a more weirder "omap[45]". Come to think of it, if 
there's a recipe that is common to all OMAPs, you can do "omap?" :)
