I think there's a hardware problem with mini PCI-E slot
on P2020RDB related to legacy IRQ routing. See this

Unfortunately the PCIe is slot already occupied, so that's why I
searched for and found the Mini PCIe Sil3132 card.
Legacy IRQ routing on PCIe is broken in what sense? Software (device
tree, kernel) or silicon (p2020) ?
It's a board design problem specific to P2020RDB. Maybe it's
fixed in latest board revisions. I have P2020RDB rev C and the
problem is still there. Freescale people on the list should know
better.
On the MSI side, I'm getting quite far on transfers, but at one point
the device stalls. Maybe a race condition in interrupt handling in
sata_sil24.c?
Sorry, cannot help you with that. I have no experience with
sata_sil24.
Felix.
