The commit: d9dbb97be0e4a550457aec5f11afefb446169c90 "mmc: dw_mmc: Zap endless timeout" removed endless loop waiting for end of dw mmc transfer.
For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) - and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB) the default timeout is to short.
The new value - 4 minutes (240 seconds) - is the same as the one used in Linux kernel driver. Such fix should be good enough until we come up with better fix for this issue.
