* minute-ia: ish software panicDenis Brockus2019-06-111-3/+8
| | | | | | | | | | | | | | | | | | | Adding functions for software panic to ISH. This includes panic_set_reason, panic_get_reason and software_panic. Added extra output when a software panic is detected. Had to touch nds32/panic.c in order to make panic_sw_reasons common.

* samus: panic reboot EC if PD MCU crashesAlec Berg2015-02-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Use the EC to check if PD MCU has crashed. The EC knows this by checking the PD status bits: if PD MCU was in RW, and is now in RO, AND it did not get to RO via a sysjump, then it must have crashed. When the EC detects this, the EC will also panic and reboot the entire system, so that we can software sync to a known good state. Also, when EC panics due to PD crash, it will log panic info. BUG=chrome-os-partner:36636 BRANCH=samus TEST=load onto samus EC and PD, try sysjump'ing back and forth on PD MCU console and verify EC does not do anything. Crash the PD MCU when in RW by reboot command and crash divzero command, and make sure the EC panics with PD crash panic message. Crash the PD MCU when in RO (before sysjumping to RW) and make sure EC does not panic.

* cortex-m*: Save panicinfo on non-exception panicsShawn Nematbakhsh2015-02-181-0/+23
Make non-exception "software" panics such as stack overflow and assert failure save a panic log. Log the panic type in r4, and misc. panic data in r5 so that panic reasons can be distinguished. BUG=chrome-os-partner:36744 TEST=Manual on samus_pd. Run 'crash divzero' then 'panicinfo' after reboot. Verify that panic info is printed with "r4 :dead6660". Trigger stack overflow, verify that panic info is printed with "r4 :dead6661".
