This series adds support for reusing existing barebox PCI drivers under EFI. This means implementation of the EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL_GUID, instead of EFI_PCI_IO_PROTOCOL_GUID, which abstracts the devices and handles enumeration. This was tested with the default QEMU x86_64 machine and OVMF (Tianocore) as UEFI firmware and an emulated 8250_pci (driver included in this series): qemu-system-x86_64 -pflash OVMF.fd -device pci-serial,chardev=cdev0 \ -chardev file,id=cdev0,path=COM -nographic /dev/sdb Driver is written against UEFI Specification 2.1D. This is my first dabble with PCI controllers, so please take a more thorough look. Thanks!
