In case CONFIG_SYSRESET is set, do_reset from reset.c will not be available anywere, even if SYSRESET is disabled for SPL in the board specific header file like this:
#if defined(CONFIG_SPL_BUILD) #undef CONFIG_WDT #undef CONFIG_WATCHDOG #undef CONFIG_SYSRESET #define CONFIG_HW_WATCHDOG #endif
'do_reset' is called from SPL for instance from the panic handler in case SPL_USB_SDP is enabled and PANIC_HANG is not set.
Setting PANIC_HANG would solve this issue, but it also changes the behavior in case a panic occurs.
