Some of the Apple desktop machine have a PCI ASMedia XHCI controller that needs firmware to be uploaded to function. This firmware is placed on the EFI system partition by the Asahi installer. So this series sets up a file system firmware loader that reads from that partition and ports the Linux driver that uploads this firmware to the controller. With this series, users can use USB devices (such as a keyboard) when they are connected to USB ports handled by the ASMedia XHCI controller. This includes the type-A ports on the M2 Mac mini for example.
