disable and enable all interrupt in stm32mp1

[Ara.1]

Is there any way to disable and enable all interrupts in a assembly way, because i need to manually switch on and OFF particular GPIO before UBOOT SPL start

uboot-source/board/st/stm32mp1/board.c

void board_debug_uart_init(void)

{

// disable interrupts ---- need support here

//PWM self logic written

// enable interrupts ---- need support here

}

Hi @Ara.1​ 

is that you asked for ?

void Enable_Irq(void)
{
  unsigned long temp;
  __asm__ __volatile__("mrs %0, cpsr\n"
           "bic %0, %0, #0x80\n"
           "msr cpsr_c, %0"
           : "=r" (temp)
           :
           : "memory");
}
 
void Disable_Irq(void)
{
  unsigned long temp;
  __asm__ __volatile__("mrs %0, cpsr\n"
           "orr	%0, %0, #0x80\n"
           "msr cpsr_c, %0"
           : "=r" (temp)
           :
           : "memory");
}
 
void Enable_Fiq(void)
{
  unsigned long temp;
  __asm__ __volatile__("mrs %0, cpsr\n"
           "bic %0, %0, #0x40\n"
           "msr cpsr_c, %0"
           : "=r" (temp)
           :
           : "memory");
 
}
 
void Disable_Fiq(void)
{
  unsigned long temp;
  __asm__ __volatile__("mrs %0, cpsr\n"
           "orr	%0, %0, #0x40\n"
           "msr cpsr_c, %0"
           : "=r" (temp)
           :
           : "memory");
}
