From 2e721094a70a52206af2e1bf1208d9a7131f6dad Mon Sep 17 00:00:00 2001 From: Yuri Tikhonov Date: Thu, 21 Feb 2008 14:23:42 +0100 Subject: lwmon5: enable hardware watchdog Some boards (e.g. lwmon5) may use rather small watchdog intervals, so causing it to reboot the board if U-Boot does a long busy-wait with udelay(). Thus, for these boards we have to restart WD more frequently. This patch splits the busy-wait udelay() into smaller, predefined, intervals, so that the watchdog timer may be resetted with the configurable (CONFIG_WD_PERIOD) interval.
