[PATCH] ARM: stm32: Initialize TAMP_SMCR BKP..PROT fields on STM32MP15xx

2024-04-14 Thread Marek Vasut
In case of an OTP-CLOSED STM32MP15xx system, the CPU core 1 cannot be released from endless loop in BootROM only by populating TAMP BKPxR 4 and 5 with magic and branch address and sending SGI0 interrupt from core 0 to core 1 twice. TAMP_SMCR BKP..PROT fields must be initialized as well to release t
