This is very much desirable, in todays times. In angstrom e.g. we want to generalize feeds across
many machines for arm especially, so we can share common feeds across multiple armv7a machines
so BSP maintainers have to start thinking that their BSP layer will be put along with other BSP layers
and they not change common components mindlessly to fit for just one given machine.

secondly more and more end users especially big companies have more than 1 machine tied into their useless
so its desirable for them to use one distro across all the product lines and hence a requirement to have
BSP layers play well with each others.
