To do that the vexpress config fragment will need to be a topic branch
on the ARM Landing Teams git, and every topic which changes a config
needs to be stacked on top of that. Is that what is expected?

Currently I have two separate topics with monolithic Android and Ubuntu
configs, so if we are moving over to config fragments I can delete
these?

That sounds fair enough, and meets the current requirements. We can deal
with other requirements as the become apparent.
