- boot_info: label the ESP32 reset reasons Zephyr's hwinfo driver maps to 0
(USB-Serial-JTAG/JTAG reset -> DEBUG, power glitch -> BROWNOUT, CPU lockup,
eFuse -> HARDWARE); get pwrmgt.bootreason no longer says Unknown after a flash
- mqtt: the uplink credentials struct moves to adapters/mqtt/uplink_creds.h,
so the adapter no longer includes an app header (layout unchanged: the
struct is persisted raw)
- gps: one off-levels routine for standby/off and System OFF; the sleep line
stays asserted in standby and drops at System OFF, as upstream's
sleep_gps/stop_gps/powerOff; System OFF now asserts reset before cutting
GPS_EN
- doom: sprites solid with a one-pixel black halo, boss drawn 1.5x on the
floor; the L2 boss was invisible from the spawn on 1-bit panels
hwinfo_get_reset_cause() reads a latched register. It was read inline in
main_companion.cpp and cleared there, so the repeater, room server and
observer never read it and never cleared it: their flags carried into the next
boot, and whichever role read first defined what any later reader would see.
helpers/boot_info.c reads it once in a SYS_INIT at POST_KERNEL, logs it,
stores it and clears the register. That runs before main() on every role.
zephcore_boot_reset_cause() hands out the stored copy and reports false where
the platform has no support, which a caller can distinguish from a cause of 0.
The clear's return is discarded deliberately: ESP32 has no
hwinfo_clear_reset_cause() implementation, so the weak stub returns -ENOSYS.
The capture is still correct there; only the next boot's reading is not.
Logging in boot_info_init() rather than only in the consuming role matters
because the clear now happens everywhere. Without it a repeater that rebooted
on WATCHDOG or LOCKUP would have the evidence cleared and recorded nowhere,
where before it survived in the register for whoever read it over SWD.
main_companion.cpp reads the stored copy and renders through a table with one
row per RESET_* bit, so a cause with no label is no longer logged as bare hex.
