mtip32xx: Fix ERO and NoSnoop values in PCIe upstream on AMD systems
A hardware quirk in P320h/P420m interfere with PCIe transactions on some AMD chipsets, making P320h/P420m unusable. This workaround is to disable ERO and NoSnoop bits in the parent and root complex for normal functioning of these devices NOTE: This workaround is specific to AMD chipset with a PCIe upstream device with device id 0x5aXX Signed-off-by: Asai Thambi S P <asamymuthupa@micron.com> Signed-off-by: Sam Bradshaw <sbradshaw@micron.com> Cc: stable@kernel.org Signed-off-by: Jens Axboe <axboe@fb.com>
