[U-Boot] [PATCH 7/9] kmp204x: set CPU watchdog reset reason flag

Check the core timer status register (TSR) for watchdog reset, and and set the QRIO's reset reason flag REASON1[0] accordingly. This allows the appliction SW to identify the cpu watchdog as a reset reason, by setting the REASON1[0] flag in the QRIO. Signed-off-by: Rainer Boschung rainer.bosch

[U-Boot] [PATCH 5/9] kmp204x: CPU watchdog enabled

The booting of the board is now protected by the CPU watchdog. A failure during the boot phase will end up in board reset. Signed-off-by: Rainer Boschung rainer.bosch...@keymile.com --- include/configs/km/kmp204x-common.h | 8 1 file changed, 8 insertions(+) diff --git a/include

[U-Boot] CPU Wachtog for P2041

I am using the core watchdog of the P2041 on the kmp204x board. For the watchdog initialization I use the mpc85xx framework and the powerpc register definitions. However, I had to modify both for the following reasons (Patches 1 to 4): -the e500mc register implementation differs from other ppc
