Problem using Sil 3132 Sata2 controller with X5000

Unfortunately, we've received many emails from X5000 users who are unable to use the Sil3132 controller on their machines.
We've investigated the issue and it's NOT a driver problem, but we believe it's a problem with the X5000 firmware. The card isn't recognized by uboot, which doesn't initialize it, and therefore the driver can't work.
A-Eon therefore needs to investigate the issue regarding PCIe slot management.

The AmigaOne (SE/XE/µA1) U-Boot versions don't initialize any IT, SII, LSI/NCR, etc. PCI(e) PATA, SATA and SCSI hardware either, but sg2's AmigaOS 4.x drives for it are still working on any supported hardware. At least his SII 3112 and 3114 drivers are working on the Sam440EP the same way well, using completely different versions of U-Boot.
i.e. it can't be U-Boot version related at all.
The sam460sata.device and the sii3132sata.device drivers probably don't include any code from sg2's PATA/SATA/SCSI AmigaOS 4.x drivers, which makes it even more likely that it's a bug in those drivers.

The Sil3132 controller is not recognized at all on the PCIe bus, so this is not the same situation you reported with the AmigaOne example.
It could be an incompatibility between the PCIe bridge and the controller, or an incorrect configuration of the PCIe bridge.

Since the controller is not visible at all, the driver cannot do anything about it.
