[U-Boot] Intialisation of Interrupts

[Flash K]

Hi Graeme,

I was going through the U-boot code. Could you please help me with the following? I wanted to know as to where the CPU interrupts are initialised. I believe it should be along with the CPU initialisation and before the northbridge and southbridge intialisation. I wanted to implement a logic to read the state of a GPIO pin and carry out some action based on this key press. I want to do this before the Bootloader is invoked. 


Regards,
