This is a series of small fixes and cleanups either required by those fixes, or enabled now that the fixes are made.
I hope that either patch 1 or 4 might fix the issues Jörg is seeing, but I'm not sure that will happen. The other patches shouldn't change any behaviour.
Stephen Warren (6): usb: ci_udc: fix ci_flush_{qh,qtd} calls in ci_udc_probe() usb: ci_udc: don't assume QTDs are adjacent when transmitting ZLPs usb: ci_udc: lift ilist size calculations to global scope usb: ci_udc: fix items array size/stride calculation usb: ci_udc: remove controller.items array usb: ci_udc: don't memalign() struct ci_req allocations

Good news! The last patch usb: ci_udc: don't memalign() struct ci_req allocations removes the timeout error after starting the fourth run of tftp in a row.
This is how I tested. Checked out u-boot-usb/master branch. Applied the necessary patches to support our board. Applied the patches step after step. After applying a patch reset the board and run tftp from console until an error occured, which is always the fourth run. This is the case until applying patch usb: ci_udc: don't memalign() struct ci_req allocations, which throws no timeout error within running tftp about 60 times in a row.
