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.
