From 1f003cf4738a199d99c818124784058526d2d40e Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 9 Oct 2009 02:24:33 -0400 Subject: [PATCH] Blackfin: reset watchdog in udelay() All arches apparently should reset the watchdog in their udelay loop as noted on the mailing list recently: > A comment in flash_status_check() suggests that udelay() is > expected to reset the watchdog, but I can't find any architecture > where it does. If this is missing in other architectures, it should be fixed at the root cause, i. e. in udelay() or in the respective support routines.
