      sparc32: genirq support · 6baa9b20
      Sam Ravnborg authored
      The conversion of sparc32 to genirq is based on original work done
      by David S. Miller.
      Daniel Hellstrom has helped in the conversion and implemented
      the shutdowm functionality.
      Marcel van Nies <morcles@gmail.com> has tested this on Sparc Station 20
      
      Test status:
      sun4c      - not tested
      sun4m,pci  - not tested
      sun4m,sbus - tested (Sparc Classic, Sparc Station 5, Sparc Station 20)
      sun4d      - not tested
      leon       - tested on various combinations of leon boards,
                   including SMP variants
      
      generic
         Introduce use of GENERIC_HARDIRQS and GENERIC_IRQ_SHOW
         Allocate 64 IRQs - which is enough even for SS2000
         Use a table of irq_bucket to maintain uses IRQs
            irq_bucket is also used to chain several irq's that
            must be called when the same intrrupt is asserted
         Use irq_link to link a interrupt source to the irq
         All plafforms must now supply their own build_device_irq method
         handler_irq rewriten to use generic irq support
      
      floppy
         Read FLOPPY_IRQ from platform device
         Use generic request_irq to register the floppy interrupt
         Rewrote sparc_floppy_irq to use the generic irq support
      
      pcic:
         Introduce irq_chip
         Store mask in chip_data for use in mask/unmask functions
         Add build_device_irq for pcic
         Use pcic_build_device_irq in pci_time_init
         allocate virtual irqs in pcic_fill_irq
      
      sun4c:
         Introduce irq_chip
         Store mask in chip_data for use in mask/unmask functions
         Add build_device_irq for sun4c
         Use sun4c_build_device_irq in sun4c_init_timers
      
      sun4m:
         Introduce irq_chip
         Introduce dedicated mask/unmask methods
         Introduce sun4m_handler_data that allow easy access to necessary
           data in the mask/unmask functions
         Add a helper method to enable profile_timer (used from smp)
         Added sun4m_build_device_irq
         Use sun4m_build_device_irq in sun4m_init_timers
      
         TODO:
            There is no replacement for smp_rotate that always scheduled
            next CPU as interrupt target upon an interrupt
      
      sun4d:
         Introduce irq_chip
         Introduce dedicated mask/unmask methods
         Introduce sun4d_handler_data that allow easy access to
         necessary data in mask/unmask fuctions
         Rewrote sun4d_handler_irq to use generic irq support
      
         TODO:
            The original implmentation of enable/disable had:
      
                if (irq < NR_IRQS)
                     return;
      
            The new implmentation does not distingush between SBUS and cpu
            interrupts.
            I am no sure what is right here. I assume we need to do
            something for the cpu interrupts.
      
            I have not succeeded booting my sun4d box (with or without this patch)
            and my understanding of this platfrom is limited.
            So I would be a bit suprised if this works.
      
      leon:
         Introduce irq_chip
         Store mask in chip_data for use in mask/unmask functions
         Add build_device_irq for leon
         Use leon_build_device_irq in leon_init_timers

      sparc32: cleanup code for pci init · 06010fb5
      Sam Ravnborg authored
      Move the ifdeffery to a header file to make the logic more
      obvious where we decide between PCI or SBUS init

      sparc32,sun4d: rename sbus_tid to board_to_cpu in irq support · db1cdd14
      Sam Ravnborg authored
      The new name reflects the actual usage much better.
