PPC: shoud fatal exception issue a panic?

[Thomas Dörfler]

Hi,

during testing of the qemuppc BSP I hit some fata exceptions. Since the
standard exception handler in
c/src/lib/libcpu/powerpc/new-exceptions/bspsupport/vectors_init.c
performs printk("...Press Reset button..."), many systems may hang in
case of a unexpected, non-recoverable exception.

Wouldn't it make more sense to issue a BSP_panic in these cases? The BSP
should have a better idea what to do in thse cases, e.g. wait for a
pushbutton reset, force an automatic reset, force a system shutdown or
whatever is appropriate.

Any ideas? any opinions?

wkr,
Thomas.
