FYI these are only two publicly accessible Marvell A37xx documents which
do not require login to Marvell Customer portal:

http://www.marvell.com/content/dam/marvell/en/public-collateral/embedded-processors/marvell-embedded-processors-armada-37xx-product-brief-2016-01.pdf
http://www.marvell.com/content/dam/marvell/en/public-collateral/embedded-processors/marvell-embedded-processors-armada-37xx-hardware-specifications-2019-09.pdf

And for pci-aardvark.c driver they are mostly useless.

Funny part is that second document has PCIe Reset section which
mention existence of some bits in some registers but these
bits/registers are not documented in any other documentation...
