-#ifdef CONFIG_ALPHA_XL
-/*
- An AVANTI *might* be an XL, and an XL has only 27 bits of ISA address
- that get passed through the PCI<->ISA bridge chip. So we've gotta use
- both windows to max out the physical memory we can DMA to. Sigh...
-
- If we try a window at 0 for 1GB as a work-around, we run into conflicts
- with ISA/PCI bus memory which can't be relocated, like VGA aperture and
- BIOS ROMs. So we must put the windows high enough to avoid these areas.
-
- We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1,
- and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1.
- Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually
- be used for that range (via virt_to_bus()).
-
- Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb,
- to keep virt_to_bus() from returning an address in the first window, for
- a data area that goes beyond the 64Mb first DMA window. Sigh...
- The fudge factor MUST match with <asm/dma.h> MAX_DMA_ADDRESS, but
- we can't just use that here, because of header file looping... :-(
-
- Window 1 will be used for all DMA from the ISA bus; yes, that does
- limit what memory an ISA floppy or sound card or Ethernet can touch, but
- it's also a known limitation on other platforms as well. We use the
- same technique that is used on INTEL platforms with similar limitation:
- set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init().
- We trust that any ISA bus device drivers will *always* ask for DMAable
- memory explicitly via kmalloc()/get_free_pages() flags arguments.
-
- Note that most PCI bus devices' drivers do *not* explicitly ask for
- DMAable memory; they count on being able to DMA to any memory they
- get from kmalloc()/get_free_pages(). They will also use window 1 for
- any physical memory accesses below 64Mb; the rest will be handled by
- window 2, maxing out at 1Gb of memory. I trust this is enough... :-)
-
- We hope that the area before the first window is large enough so that
- there will be no overlap at the top end (64Mb). We *must* locate the
- PCI cards' memory just below window 1, so that there's still the
- possibility of being able to access it via SPARSE space. This is
- important for cards such as the Matrox Millennium, whose Xserver
- wants to access memory-mapped registers in byte and short lengths.
-
- Note that the XL is treated differently from the AVANTI, even though
- for most other things they are identical. It didn't seem reasonable to
- make the AVANTI support pay for the limitations of the XL. It is true,
- however, that an XL kernel will run on an AVANTI without problems.
