[RFC PATCHv1 0/5] Use the mvebu PCIe driver on Kirkwood

Hello,

Here is a set of five patches that demonstrate that the mvebu PCIe
driver can be used on Kirkwood with no modification at all. Those
patches are not meant to be applied yet, the Device Trees are not
completely correct yet (they don't take into account the fact that
6281 has one PCIe interface and 6282 has two PCIe interface).

It took less than two hours to enable PCIe on Kirkwood (and in those
two hours, the conversion of the DB-88F6281 board to the Device Tree
has been done as well), and the result works fine:

# /usr/sbin/lspci
00:01.0 PCI bridge: Marvell Technology Group Ltd. Device 7846
00:02.0 PCI bridge: Marvell Technology Group Ltd. Device 7846
01:00.0 SCSI storage controller: Marvell Technology Group Ltd. 88SX7042 PCI-e 4-port SATA-II (rev 02)
02:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) (rev 06)

# cat /proc/cpuinfo | grep ^Hardware
Hardware	: Marvell Kirkwood (Flattened Device Tree)

I've tested both the e1000e NIC card and the SATA 4 ports card and
they work fine.

Best regards,

Thomas
