The point in having the bootloader is because different bootloaders
may provide the functionality for the board. This is especially keen
for commercial distributions where a U-Boot fork may include fixes and
this should be used on top of the BSP default and without many changes
on the layer.

As you pointed out, the U-Boot usually has a single provider as it is
a MACHINE_ARCH package. I think it is a safe addition, isn't it?
