I directed the Armbian guys (Werner) to your patch and they included it
into their master branch.
So I got to compile an Armbian kernel in order to test the patch in my
setup with the EspressoBin Board and the AS-Media SATA-controller chips.
I've tested it and it works flawlessly :-)
Thanks!

I organized a T60 Thinkpad, pulled out the Wificard (MiniPCIE) and
plugged in the Marvell SATA-Controller card. Good news is that you're
right, the DevCap MaxPayload is 128 bytes, so I couldn't reproduce
that error on that thinkpad. I tried two different Marvell controller
cards. Wierd thing is, that both cards did not sho up in the lspci -nn
-vv command. So I'm not sure if these got recognized.
With these patches supplied (@thank you very much Marek & Björn) is
there a build server I can download a nightly version of armbian I can
test for you?
Is there any way I can support?
Thank you very much in advance!

I have no idea. My laptop only supports 512 (except for an ASMedia
USB controller). If the device advertises it, I would expect the
vendor to test it. Obviously it still could be a device defect.
They
should publish an erratum if that's the case so people know to avoid
it. So I would try to get ASMedia to say "no, that's tested and
should work" or "oh, sorry, here's an erratum and we'll fix it in the
next round."
I doubt that ASMedia publish something...
But has somebody contact to ASMedia? I can try it.
Basically these ASMedia SATA controller chips are present on more
"noname" mPCIe-form cards and I guess ASMedia is not going to support
them.
Note that we have also tested Marvell PCIe-based SATA controllers
which
support MPS of 512 bytes too and there were no problem with them on
A3720 nor CN9130.
