[Openembedded-users] Question about choice of version for a package

[Joel A Fernandes]

I hope this question doesn't come across as silly, but I'm having a hard time figuring out how does bitbake/oe get the default version for a certain package if the PREFERRED_VERSION has not been set by configuration files?

For example, when I build u-boot for a beagleboard machine, it chooses the "git" recipe. Where is this decided?

thanks,
Joel
