"There are two sets of changes in this pull.
The largest is the addition of the ColdFire platform side i2c support
(the IO addressing, setup and clock definitions). The i2c hardware

The other change is the addition of support for the Amcore board"

There is at least one Chelsio 10Gb card which uses VPD area to store some
non-standard blocks (example below). However pci_vpd_size() returns the
length of the first block only assuming that there can be only one VPD "End
Tag".
Since 4e1a635552d3 ("vfio/pci: Use kernel VPD access functions"), VFIO
blocks access beyond that offset, which prevents the guest "cxgb3" driver
from probing the device. The host system does not have this problem as its
driver accesses the config space directly without pci_read_vpd().
Add a quirk to override the VPD size to a bigger value. The maximum size
is taken from EEPROMSIZE in drivers/net/ethernet/chelsio/cxgb3/common.h.
We do not read the tag as the cxgb3 driver does as the driver supports
writing to EEPROM/VPD and when it writes, it only checks for 8192 bytes
boundary. The quirk is registered for all devices supported by the cxgb3
driver.
This adds a quirk to the PCI layer (not to the cxgb3 driver) as the cxgb3
driver itself accesses VPD directly and the problem only exists with the
vfio-pci driver (when cxgb3 is not running on the host and may not be even
loaded) which blocks accesses beyond the first block of VPD data. However
vfio-pci itself does not have quirks mechanism so we add it to PCI.
This is the controller:
Ethernet controller [0200]: Chelsio Communications Inc T310 10GbE Single Port Adapter [1425:0030]
This is what I parsed from its VPD:

We already log a "Signaling PME" whenever the PME service driver claims a
Root Port. In fact, we also log the same message for every device in the
hierarchy below the Root Port.
Log the "Signaling PME" once (only for the Root Port, since we can
trivially find out which devices are below the Root Port), and include the
IRQ number in the message to help connect the dots with /proc/interrupts.
