Так таблица есть в посте 4.

Вопрос уже когда-то поднимался, роутеры разные.
Та таблица для TL-WR703N(вернее раздел "POR Value" относится только к TL-WR703N).


Отрывок из uboot конфигурация GPIO:

void ar7240_gpio_config(void)

/* Disable clock obs

* clk_obs0(gpio1/bit19), 6(gpio11/bit20)

Скорее TL-MR3020 похож на TL-MR11U по конфигурации GPIO.
