I have a two Marvel Sata Marvell 88NV9143 controller disks on the
board. When I tried to load mvumi module
I'm getting an invalid signature error. Further debugging I found any
read on memory mapped IO returns 0xffffffff (-1).
And also the PCI bar address is 64bit where as device is 32-bit
[CPU] -> [IDT PCI-E Interconnet Switch] -> [MVUMI controller, SATA1 & SATA2]
mvumi 0000:03:00.1: invalid signature [0xffffffff].
mvumi: probe of 0000:03:00.1 failed with error -22
