Hi Jason and Sebastian,

With DT support for mv643xx_eth board specific init for some boards now
is unneccessary. Remove those board files, Kconfig entries, and
corresponding entries in kirkwood_defconfig.

Note: board-km_kirkwood.c is also removed, as Valentin Longchamp confirmed
the lock-up is not caused by accessing clock gating registers but rather
non-existent device registers. This will be addressed by dtsi separation
for kirkwood and bobcat SoC variants.

Changelog:
v3->v4:
- remove more boards that don't require board specific setup

Just a stupid note: With Thomas ongoing work to get mvebu-pcie driver in
place and enabled for kirkwood, some boards setup files will also lose
their pcie init routines, which may allow you to kill those additonal
files soon.

Yes, we're very excited about this ;-)

For instance 6bd98481ab34 (arm: kirkwood: NETGEAR ReadyNAS Duo v2 init
PCIe via DT) currently sitting in jcooper/mvebu/pcie_kirkwood removes
the PCIE init routine in board-readynas.c, and yours remove ge00
init. With both applied, the whole file can go away.

AFAICT, this may be the case soon for:

 arch/arm/mach-kirkwood/board-iconnect.c   (36e5722089)
 arch/arm/mach-kirkwood/board-mplcec4.c    (9470fbfb8d)
 arch/arm/mach-kirkwood/board-nsa310.c     (40fa8e5da2)
 arch/arm/mach-kirkwood/board-readynas.c   (6bd98481ab)
 arch/arm/mach-kirkwood/board-ts219.c      (259e234608)

Would you mind putting a patch together (for after v3.10 drops) to do
this?  If you applied Sebastian's series on top of mvebu/pcie_kirkwood,
that should get you almost there.  The last half of his series is going
in after v3.10...

You may want to try merging in mvebu/boards and mvebu/soc.  Those have
the changes to use dt for the restart and power-off drivers.  That'll
allow us to empty out a few more board files.  mvebu/dt also has a patch
from Valentin allowing us to remove the keymile board as well.

thx,

Jason.
