      sh: Decouple 4k and soft/hardirq stacks. · 110ed282
      Paul Mundt 提交于
      While using separate IRQ stacks can cut down on stack consumption,
      many users can also use 4k stacks directly without the additional
      need of separate stacks for soft and hardirqs.
      
      With this split, we support the same rationale for 4KSTACKS as
      m68knommu, with the IRQSTACKS abstraction as per ppc64.

      sh: Make kgdb i-cache flushing less inept. · 01bd5e9e
      Paul Mundt 提交于
      kgdb had its own ranged I-cache flushing routine that attempted to
      duplicate the flush_icache_range() functionality, but managed to do
      an explicit D-cache writeback & invalidate twice on SH-4. This is
      a no-op for SH-3, and the flush_icache_range() semantics already do
      what kgdb was feebly attempting to do already, so just move over to
      that and kill off the wrapper.

      The kgdb console setup was callable from a left-over deferred
      initialization path, which in turn depends on __init symbols. Since
      the deferred initialization was removed some time ago, kill off the
      rest of those remnants and move kgdb_init() and friends to __init.

      There was a very preliminary bunch of SMP code scattered around for the
      SH7604 microcontrollers from way back when, and it has mostly suffered
      bitrot since then. With the tree already having been slowly getting
      prepped for SMP, this plugs in most of the remaining platform-independent
      bits.

      sh: Add maple bus support for the SEGA Dreamcast. · 17be2d2b
      Adrian McMenamin 提交于
      The Maple bus is SEGA's proprietary serial bus for peripherals
      (keyboard, mouse, controller etc). The bus is capable of some
      (limited) hotplugging and operates at up to 2 M/bits.
      
      Drivers of one sort or another existed/exist for 2.4 and a rudimentary
      port, which didn't support the 2.6 device driver model was also in
      existence.
      
      This driver - for the bus logic itself and for the keyboard (other
      drivers will follow) are based on the code and concepts of those old
      drivers but have lots of completely rewritten parts.
      
      I have the maple bus code as a built in now as that seems the sane and
      rational way to handle something like that - you either want the bus
      or you don't.
