Subject: [U-Boot] [PATCH] mmc: dw_mmc: Increase timeout to 4 minutes (as in Linux kernel)
Date: Fri, 25 Sep 2015 18:25:25 +0200	[thread overview]
Message-ID: <1443198325-22460-1-git-send-email-l.majewski@samsung.com> (raw)
In-Reply-To: <1440769821-24005-1-git-send-email-l.majewski@samsung.com>

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.
