[PATCH] arm: kirkwood: convert NETGEAR ReadyNAS Duo v2 to use DT for the PCIe interface

[arno@natisbad.org (Arnaud Ebalard)]

Hi Jason and Thomas,

Thomas, I am following your work on PCIe support for a .dts file I am
working on for (Armada 370-based) Netgear ReadyNAS 102 and noticed your
set of patches to convert kirkwood-based boards to use it in order to
simplify/remove board specific code.

Jason, I gave your associated branch (jcooper/mvebu-next/pcie) a try
with following patch applied and can confirm USB 3.0 host controller
(connected to PCIe bus) is usable on Netgear ReadyNAS *Duo v2*
(88f6282-based brother of the 102).

Note that I had to s/of_pci_range_parser()/of_pci_range_parser_init()/
in drivers/pci/host/pci-mvebu.c to compile the kernel (this may already
have been fixed already):

CHK     kernel/config_data.h
drivers/pci/host/pci-mvebu.c: In function ?mvebu_pcie_probe?:
drivers/pci/host/pci-mvebu.c:742:2: error: implicit declaration of function ?of_pci_range_parser? [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[3]: *** [drivers/pci/host/pci-mvebu.o] Error 1
make[2]: *** [drivers/pci/host] Error 2
make[1]: *** [drivers/pci] Error 2
make[1]: *** Waiting for unfinished jobs....

Can one of you take the patch below into account? Or 

Cheers,

a+
