mpc52xx_get_irq - Get pending interrupt number hook function
Called by the interrupt handler to determine what IRQ handler needs to be executed.
Status of pending interrupts is determined by reading the encoded status register. The encoded status register has three fields; one for each of the types of interrupts defined by the controller - 'critical', 'main' and 'peripheral'. This function reads the status register and returns the IRQ number associated with the highest priority pending interrupt. 'Critical' interrupts have the highest priority, followed by 'main' interrupts, and then 'peripheral'.
The mpc5200 interrupt controller can be configured to boost the priority of individual 'peripheral' interrupts. If this is the case then a special value will appear in either the crit or main fields indicating a high or medium priority peripheral irq has occurred.
This function checks each of the 3 irq request fields and returns the first pending interrupt that it finds.
This function also identifies a 4th type of interrupt; 'bestcomm'. Each bestcomm DMA task can raise the bestcomm peripheral interrupt. When this occurs at task-specific IRQ# is decoded so that each task can have its own IRQ handler.
