thorpej 433c3cae0f Pull thorpej-bus-dma branch into mainline. 1997-06-06 23:10:23 +00:00
thorpej b84a8f42d9 Implement eisa_mem_{alloc,free}(), a method for allocating/freeing
EISA bus physical address space.

This i386 implementation allocates system physical address space
after the end of RAM.

cgd cd9ef2be9c make the EISA code look a bit more like the PCI code, in the way
the bus is configured, interrupts are handled, etc.  define
eisa_chipset_tag_t and eisa_intr_handle_t types, and the following
functions:
        eisa_attach_hook()
        eisa_maxslots()
        eisa_intr_map()
        eisa_intr_string()
        eisa_intr_establish()
        eisa_intr_disestablish()
to do the right things for the i386.

cgd fedca4f133 Attach isa, eisa, and pci to mainbus now, rather than root. The i386
now has a single device tree (rather than a forest).  Also, attach
EISA only if it's present, and attach in order: PCI, EISA, ISA (most
specific to least specific).
