Not sure what is the status of mach-shmobile with regard to the device
tree, but one of the idea of the device tree is to avoid having one .c
file per board, and therefore one DT_MACHINE_START definition per
board. There should be only only DT_MACHINE_START definition per SoC or
SoC family, with the DT giving the detailed hardware description.

Of course, during a transition period, not all your drivers may have DT
bindings, and therefore some devices may need to be probed in the "old"
way (manual registration of platform_device). In that case, your
->init_machine() hook can call initialization function on a per-board
basis by testing if the machine is such or such board.

See arch/arm/mach-kirkwood/board-dt.c for an example. The advantage is
that with this solution, the board specific C files are progressively
reducing in size as more and more devices get registered through the
Device Tree, until the point where they become empty and can be removed.

Best regards,

Thomas

Hi Thomas,

shmobile is very much in the transition phase and we are, patch by patch,
working towards full(er) DT support for boards, SoCs and drivers. I am not
sure that now is the right time to jump to a approach similar to that taken
by mach-kirkwood/board-dt.c.

Ok, I understand that for transition needs, each SoC family may need a
different method. My comment was more a general comment to make sure
that the right final direction is being taken. For sure the
intermediate steps may be different.

    And enables performance events on the Armadillo board. Perhaps the

    I think you should either align '=' with tabs, or not bother doing this, 
not both. :-)

As I understand things, the Armadillo is currently the only
board in-tree that uses the r8a7740 SoC and it seems
reasonable to enable performance events to activate the
code that comprises the rest of the patch.

So while I don't feel strongly about this I do have a slight preference
for the current single-patch approach.

Thanks, there seems to be an extra tab there.

I'll roll this into an updated patch and series once
we come to a consensus about the defconfig change.
