From e262efe35742c1ad4b0966ff501efc26f34a0aec Mon Sep 17 00:00:00 2001 From: Yuri Tikhonov Date: Mon, 4 Feb 2008 14:11:03 +0100 Subject: The patch introduces the CRITICAL feature of POST tests. If the test marked as POST_CRITICAL fails then the alternative, post_critical, boot-command is used. If this command is not defined then U-Boot enters into interactive mode.

Note that an earlier version of this patch which used microseconds instead of ticks dis not work. The problem was that we used usec2ticks() to convert microseconds into ticks. usec2ticks() uses get_tbclk(), which in turn calls get_sys_info(). It turns out that this function does a lot of prolonged operations (like divisions) which take too much time so we do not trigger the watchdog in time, and it resets the system.
