    sh: rework intc2 code · d619500a
    Magnus Damm authored
    The shared intc2 code currently contains cpu-specific #ifdefs.
    This is a tad unclean and it prevents us from using the shared code
    to drive board-specific irqs on the se7780 board.
    
    This patch reworks the intc2 code by moving the base addresses of
    the intc2 registers into struct intc2_desc. This new structure also
    contains the name of the controller in struct irq_chip. The idea
    behind putting struct irq_chip in there is that we can use offsetof()
    to locate the base addresses in the irq_chip callbacks.
    
    One logic change has been made - the original shared intc2 code
    enabled the interrupts by default but with this patch they are all
    disabled by default.
