We need to do more of those before we see significant reductions from
being able to remove a lot of the existing board files. At the same

see supported. The tactical answer that I'd give to them is that they
can still add board files, provided that they also help do the work
that is required to remove them later (depends the specific capabilities
of the people and the complexity of the code they want to add).

Hi Arnd,

Thanks for the feedback. I think this thread went from the specific
case of this 2363, Wayland board into a broader discussion. I
understand this is because of the arm subarch cleanup goals. To help
people like me who aren't familiar with the details, could you
elaborate on "can still add board files" and "the work that is
required to remove them later". Do you mean I could still submit a
patch like arch/arm/mach-mmp/wayland* and you'd be willing to take it,
but with the expectation that it would be removed at a later date? Is
the removal work to do with adding device tree support (I assume
that's a bootloader task as well as a subarch/board support task)? I'm
happy to help with what I can but I'm very slow. I'm even having
trouble just getting mainline to boot on the board. [1]

Thanks,
jaya
