Problems with PCIe devices on LS1021A

Hi,

 

I get some problem while trying to enable a Marvell PCIe to SATA card.

It can be recognized in system,

# lspci

0000:00:00.0 PCI bridge: Freescale Semiconductor Inc Device 0e0c (rev 10)

0001:00:00.0 PCI bridge: Freescale Semiconductor Inc Device 0e0c (rev 10)

0001:01:00.0 SATA controller: Marvell Technology Group Ltd. 88SE9235 PCIe 2.0 x2 4-port SATA 6 Gb/s Controller (rev 11)

 

but I get some error to enable it.

ahci 0001:01:00.0: BAR 0: can't reserve [io  0x4810000020-0x4810000027]

ahci: probe of 0001:01:00.0 failed with error -16

 

This error code means resource busy, right? But there is only one PCIe device.

I have tried an Intel PCIe NIC and it can work normally.

Can anyone give me some ideas?

 

Thanks
