if its pinned using PREFERRED_VERSION in a conf file thats the first 
choice e.g. PREFERRED_VERSION_u-boot = "1.2"

if not then it goes and looks for DEFAULT_PREFRENCES in recipes which 
all provide u-boot and choses the one with highest value

If DEFAULT_PREFERENCE is same for given recipes then it picks the one 
which has newer version e.g. 1.2.3 will be picked over 1.2.2
