/**
|
|
* @brief ROM patch for systimer HAL
|
|
*
|
|
* Some chips have systimer HAL implementations in ROM that require patches.
|
|
* This file provides the necessary patches when ROM implementation is used.
|
|
*
|
|
* For chips with ESP_ROM_SYSTIMER_INIT_PATCH defined (e.g., ESP32-C5, ESP32-C6,
|
|
* ESP32-H2, ESP32-P4), the ROM systimer_hal_init/deinit functions do not
|
|
* enable ETM, so we need to patch them here.
