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.
I think, that you should adjust the commit message, because it describes the result of the real problem which is in the background.
It doesn't fix the DFU, because it wasn't broken. What is the real problem and how does this commit fix it?
I think this message is good enough (esp since I want to apply it now) and will link back to all of these other messages about it for details.
