Hi Guenter,
Great thanks for your suggestion and review,
I have some questions below , would you please help me out?

Are you saying: the first timeout == the second timeout
|-------------WS0
|-------------WS1
Sorry, could you let me know where is that suggestion??
I have checked the SBSA again, but I can not find it.
Maybe I really miss this part.

Yes, you are right, if we only use "WOR", then the first timeout ==
the second timeout

although there is only one counter, and it is 32 bits wide.
In SBSA, we can see this:
-------
Note: the watchdog offset register is 32 bits wide. This gives a
maximum watch period of around 10s at a system counter frequency of
400MHz.
If a larger watch period is required then the compare value can be
programmed directly into the compare value register.
-------
So for the first timeout, we can set the compare value register(WCV).
Then the two timeouts are different. and the first timeout has not
10s(@400MHz) limit.
just the the second timeout must use "WOR".

yes, thanks for pointing it out.
I found this problem in my first upstream patchset.
So in this patchset, there is not that problem now:
-------
do {
wcv_hi = sbsa_gwdt_cf_read(SBSA_GWDT_WCV_HI, wdd);
wcv_lo = sbsa_gwdt_cf_read(SBSA_GWDT_WCV_LO, wdd);
} while (wcv_hi != sbsa_gwdt_cf_read(SBSA_GWDT_WCV_HI, wdd));

yes, this patchset has fully support ACPI and FDT, and has been
successfully tested on
(1)Foundation model
(2)AMD Seattle B0 Soc

I think that is not a contentious issue.
Just some one has that suggestion, then we discussed it.
So I am going to delete ARM support.
If we have this hardware in the future, we can add it by then.

Totally agree, there is not this problem in my patchset.

in this patchset, I have totally deleted all the debug message, only keep:
(1)3 error messages
(2)2 warning messages
reason:
1. if system reset by watchdog, we need to inform user (WCS: store
watchdog status, WCV: store the timestamp of the last reboot, maybe
these can provide some basic info of reboot )
2. if watchdog has been enabled before register, there is something
wrong we need to inform user. (WCS: store watchdog status)
(3)1 info message
reason: if watchdog has been successfully registered, we log it.
Please let me know if there is any redundant massage, I will fix it.

Great thanks for your help , those help me a lot.
So, for now , this only big problem in my patchset is "pretimeout",
but I have some doubt above, would you help me out ? :-) Thanks
