Hi ML,
I'm working on a mips based SoC with an external watchdog. The watchdog
should be touched every 5 seconds in order to avoid the system reboot.
I tried to define macros like CONFIG_HW_WATCHDOG / CONFIG_WATCHDOG, but I'm not
happy for the result. For example, the serial port driver (ns165

That shgould be no problem. We have a couple of boards that have

Hi Wolfgang,
Thank you to share your experience.
Anyway, I'm not sure that the common infrastructure covers all scenarios. For
example in /common/main.c we have the code:
...
int readline_into_buffer (const char *const prompt, char * buffer)
{
...
for (;;) {
#ifdef CONFIG_BOOT_RETRY_TIM

Hi Wolfgang,
from this discussion, I have understood that the problem is that mips code
lacks the support interrupts in iv mode. I will try to do something (support
of IV modality... for example).
Thanks again,

Hi,
I have a question about watchdog support for PPC_4xx. When I define
CONFIG_WATCHDOG in canyonlands.h, I get an error when building
cpu_init.c. The error code reads:
{standard input}: Assembler messages:
{standard input}:133: Error: unsupported relocation against tcr
{standard input}

Please define exactly what you mean by "before Linux gets a chance to
load" - is it resetting in U-Boo
thing based on the PPC440 UG.
Thanks for the help.
