watchdog: sp5100_tco.c: Check if firmware has set correct value in tcobase.
commit 90d241edd13bdeef70f264b569f7e150bf23621e upstream.
Stefano found SP5100 TCO watchdog driver using wrong address.
[ 9.148536] SP5100 TCO timer: SP5100 TCO WatchDog Timer Driver v0.01
[ 9.148628] DEBUG __ioremap_caller WARNING address=b8fe00 size=8 valid=1 reserved=1
and e820 said that range is RAM.
We should check if we can use that reading out. BIOS could just program wrong address there.
