PCI-E add-on Success & Failures

[xtract]

I have been able run  a sata card based on Marvell 88SE9230, with 4 ports.

Kernel:
Linux rockpro64 4.18.0-rc8-1060-ayufan-g45828c4db727 #1 SMP PREEMPT Thu Aug 9 19:41:21 UTC 2018 aarch64 GNU/Linux

Code:

    Kernel driver in use: ahci

To get the rp64 I had to manually bind the ahci driver to the pcie card, adding a udev rule:

Code:

root@rockpro64:~# cat /etc/udev/rules.d/99-marvell.rules
RUN+="/bin/bash -c 'echo 0000:01:00.0 > /sys/bus/pci/drivers/ahci/bind'"

I have only tried with one drive yet, the second one is on its way
