I figured out the various ports on the muitiport card and have 2 sata drives I am testing with.
One drive works fine. But two drives it is a bit of a guess which one will come in as /dev/sda (the mSD card is /dev/mmcblk0). And only one drive is visible. Or at least gparted is only seeing one.
From messages back last fall? I had that this board would let me use multiple sata drives, so there seems to be something I am missing.
Right now each item has its own power supply: Cubietruck, Multiport card, Drive1, and Drive2. So it is not a power issue (or shouldn't be).
I went searching for information on sata port multiplier and found:
http://www.spinics.net/lists/arm-kernel/msg377619.html
Is this still the status of this and if so how do I set AHCI_HFLAG_NO_PMP to true?
But it seems there were more messages about this...

Well if you read the message you reference it states:
"So add a module parameter to enable pmp usage, and default this to off, so that directly attached disks keep working normally."
So it seems if you use a multiple you need to do a different option than without so it indicates it would need it. If you do "modinfo ahci_sunxi" you'll see that actually the patch has landed and there is a enable_pmp parameter. So you'll need to create something like /etc/modprobe.d/sunxi.conf and add a line "options ahci_sunxi enable_pmp=1" line (no I've not verified that is correct so you'll need to check it) and reboot.

Not entirely, it should also work having ahci_sunxi.enable_pmp=1 on kernel
cmdline. Also, you may need to rebuild initramfs by running dracut -f after modifying modprobe.d files.

No, if you modify kernel command line, you don't need to rebuild
initramfs, since module parameters are read from kernel cmdline. But if you modify some of files in modprobe.d and impacted module is loaded in initramfs environment, you need to rebuild initramfs to include those modifications made in modprobe.d

It only matters if he's booting the OS off the SATA, if it's rootfs is on MMC and say /home is on SATA is can load it later once root is switched.

I do want to have /boot and / on one of the sata drives. Eventually. I havew already tested only having uboot on the MMC and then have the boot switch to sata. But here there are multiple satas and how will sda be selected?
In this case:
Can I run with the append and not modify initramfs.
And BTW, with the power demand and other aspects, I am seriously questioning if this is better than a 1TB internal sata and all the rest on USB.
I may end up selling this card to someone else who wants to work with it...
