[PATCH V3 4/4] serial: sprd: adjust TIMEOUT to a big value

From: Chunyan Zhang
Date: Thu Mar 02 2017 - 01:31:03 EST


From: Wei Qiao <wei.qiao@xxxxxxxxxxxxxx>

SPRD_TIMEOUT was 256, which is too small to wait until the status
switched to workable in a while loop, so that the earlycon could
not work correctly.
