From eb0615bf600d2caf5aa2958f47f5ba364c52d5e7 Mon Sep 17 00:00:00 2001 From: Yuri Tikhonov Date: Thu, 24 Apr 2008 10:30:53 +0200 Subject: [PATCH] lwmon5: watchdog POST fix Use the GPT0_MASKx registers as the temporary storage for watch-dog timer POST test instead of GPT0_COMPx. The latter (GPT0_COMP1..GPT0_COMP5) are used for the log-buffer header.
