which patch are you referring to?
i see the config in the boot pack already have PciRoot(0x0)/Pci(0x1c,0x0)/Pci(0x0,0x0) to dw1820a? I didn't change anything from the bootpack except "scanpolicy"
i see you have <string>pci14e4,43a0</string>, whereas dw1820a can be:
Pci14e4,43ba
Pci14e4,43a3
Pci14e4,43a0
do you mean changing this?
