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.
