not really a vulnerability per-se but funky flawed behavior nonetheless

| Boot straps are not relatched on watchdog resets (strapwn)
 +
| On boot, the BOOTSELECT, RCM and RAM_CODE straps are latched from external GPIO to determine which boot medium to use and verify from in bootrom. However, APB_MISC_PP_STRAPPING_OPT_A can be overwritten with arbitrary values following bootrom. Write access to PP_STRAPPING_OPT_A would otherwise be mundane, however these straps are not relatched during a watchdog reset (despite being latched during other software resets), allowing for arbitrary straps to be selected and executed in bootrom.

 +
This allows setting NVPROD_UART on some hardware configurations where it would normally be unavailable (ie on Jetson Nano boards), but is otherwise mostly useless and/or useful for testing unintended boot options (such as USB Mass Storage boot) without having to move boot strap resistors.
