See: https://github.com/Nitrokey/nethsm-grub/commits/nethsm-z790?since=2025-01-13&until=2025-01-13 And more generally, see branch: https://github.com/Nitrokey/nethsm-grub/commits/nethsm-z790 This brings in a few minor fixes, and also a not-so-minor fix: Add TT (transaction translation) handling for non-SuperSpeed devices in xhci.c More generally, this patchset will improve non-root hub support in the xHCI code. There is also a patch to work around a quirk on the MSI Z790-P mainboard, which I'm planning to add to Libreboot at a later date. Signed-off-by: Leah Rowe <leah@libreboot.org>

Subject: [PATCH 18/26] grub-core/bus/usb/usbhub: Add new private fields for
|
|
xHCI controller
|
|
|
|
Store the root port number, the route, consisting out of the port ID
|
|
in each nibble, and a pointer to driver private data.
