[RFC PATCH 0/3] PCI: generate proper configuration access cycles
From: Jisheng Zhang
Date: Mon Oct 26 2015 - 07:07:04 EST
Inspired by Russell King's patch[1], I found some pci hosts also have the
same issue of "reading 32-bits from the command register, modifying the
command register, and then writing it back has the effect of clearing
any status bits that were indicating at that time" as pointed out by
Russell. Fix them by using the pci_generic_config_write.
Another problem is do we need to use proper readb/readw for config read?
