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.
