I'm in two minds about removing the BBL bootloader at the moment...

...on one hand I can see that OpenSBI should be used for all RISC-V
projects going forward, but on the other hand there still seem to be a
number of RISC-V projects that are using riscv-pk /BBL (and Buildroot),
e.g. Ariane/OpenPiton, Shakti C-class and LowRISC (for Rocket core).
Keeping BBL support within Buildroot at least gives people a smoother
upgrade path, i.e. riscv-pk + Buildroot -> Buildroot (with integrated
riscv-pk) -> Buildroot (with integrated OpenSBI).

I know that most 'desktop' distros are moving, or are planning to move,
to OpenSBI, but I'm not so sure about the situation for people working
with softcores/FPGAs or more deeply embedded systems.

Thoughts?

Mark
