+   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.
+
+   %%% All of this should be obviated by the ability to route
+   everything through the iommu.

+
+/*
+ * NOTE: The LCA uses a Host Address Extension (HAE) register to access
+ *       PCI addresses that are beyond the first 27 bits of address
+ *       space.  Updating the HAE requires an external cycle (and
+ *       a memory barrier), which tends to be slow.  Instead of updating
+ *       it on each sparse memory access, we keep the current HAE value
+ *       cached in variable cache_hae.  Only if the cached HAE differs
+ *       from the desired HAE value do we actually updated HAE register.
+ *       The HAE register is preserved by the interrupt handler entry/exit
+ *       code, so this scheme works even in the presence of interrupts.
+ *
+ * Dense memory space doesn't require the HAE, but is restricted to
+ * aligned 32 and 64 bit accesses.  Special Cycle and Interrupt
+ * Acknowledge cycles may also require the use of the HAE.  The LCA
+ * limits I/O address space to the bottom 24 bits of address space,
+ * but this easily covers the 16 bit ISA I/O address space.
+ */
+
+/*
+ * NOTE 2! The memory operations do not set any memory barriers, as
+ * it's not needed for cases like a frame buffer that is essentially
+ * memory-like.  You need to do them by hand if the operations depend
+ * on ordering.
+ *
+ * Similarly, the port I/O operations do a "mb" only after a write
+ * operation: if an mb is needed before (as in the case of doing
+ * memory mapped I/O first, and then a port I/O operation to the same
+ * device), it needs to be done by hand.
+ *
+ * After the above has bitten me 100 times, I'll give up and just do
+ * the mb all the time, but right now I'm hoping this will work out.
+ * Avoiding mb's may potentially be a noticeable speed improvement,
+ * but I can't honestly say I've tested it.
+ *
+ * Handling interrupts that need to do mb's to synchronize to
+ * non-interrupts is another fun race area.  Don't do it (because if
+ * you do, I'll have to do *everything* with interrupts disabled,
+ * ugh).

+ *  controller 1: channels 0-3, byte operations, ports 00-1F
+ *  controller 2: channels 4-7, word operations, ports C0-DF
+ *
+ *  - ALL registers are 8 bits only, regardless of transfer size
+ *  - channel 4 is not used - cascades 1 into 2.
+ *  - channels 0-3 are byte - addresses/counts are for physical bytes
+ *  - channels 5-7 are word - addresses/counts are for physical words
+ *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
+ *  - transfer count loaded to registers is 1 less than actual count
+ *  - controller 2 offsets are all even (2x offsets for controller 1)
+ *  - page registers for 5-7 don't use data bit 0, represent 128K pages
+ *  - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * DMA transfers are limited to the lower 16MB of _physical_ memory.  
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ *  Address mapping for channels 0-3:
+ *
+ *   A23 ... A16 A15 ... A8  A7 ... A0    (Physical addresses)
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *   P7  ...  P0  A7 ... A0  A7 ... A0   
+ * |    Page    | Addr MSB | Addr LSB |   (DMA registers)
+ *
+ *  Address mapping for channels 5-7:
+ *
+ *   A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0    (Physical addresses)
+ *    |  ...  |   \   \   ... \  \  \  ... \  \
+ *    |  ...  |    \   \   ... \  \  \  ... \  (not used)
+ *    |  ...  |     \   \   ... \  \  \  ... \
+ *   P7  ...  P1 (0) A7 A6  ... A0 A7 A6 ... A0   
+ * |      Page      |  Addr MSB   |  Addr LSB  |   (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

+ * Core file format: The core file is written in such a way that gdb
+ * can understand it and provide useful information to the user (under
+ * linux we use the `trad-core' bfd, NOT the osf-core).  The file contents
+ * are as follows:
+ *
+ *  upage: 1 page consisting of a user struct that tells gdb
+ *      what is present in the file.  Directly after this is a
+ *      copy of the task_struct, which is currently not used by gdb,
+ *      but it may come in handy at some point.  All of the registers
+ *      are stored as part of the upage.  The upage should always be
+ *      only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *      current->brk to pick up all of the user variables, plus any memory
+ *      that may have been sbrk'ed.  No attempt is made to determine if a
+ *      page is demand-zero or if a page is totally unused, we just cover
+ *      the entire range.  All of the addresses are rounded in such a way
+ *      that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful
+ *      backtrace.  We need to write the data from usp to
+ *      current->start_stack, so we round each of these in order to be able
+ *      to write an integer number of pages.

+          Reads on the Blackfin are speculative. In Blackfin terms, this means
+          they can be interrupted at any time (even after they have been issued
+          on to the external bus), and re-issued after the interrupt occurs.
+          For memory - this is not a big deal, since memory does not change if
+          it sees a read.
+
+          If a FIFO is sitting on the end of the read, it will see two reads,
+          when the core only sees one since the FIFO receives both the read
+          which is cancelled (and not delivered to the core) and the one which
+          is re-issued (which is delivered to the core).
+
+          To solve this, interrupts are turned off before reads occur to
+          I/O space. This option controls which the overhead/latency of
+          controlling interrupts during this time
+           "n" turns interrupts off every read
+                (higher overhead, but lower interrupt latency)
+           "y" turns interrupts off every loop
+                (low overhead, but longer interrupt latency)
+
+          default behavior is to leave this set to on (type "Y"). If you are experiencing
+          interrupt latency issues, it is safe and OK to turn this off.

+ * Reads on the Blackfin are speculative. In Blackfin terms, this means they
+ * can be interrupted at any time (even after they have been issued on to the
+ * external bus), and re-issued after the interrupt occurs.
+ *
+ * If a FIFO is sitting on the end of the read, it will see two reads,
+ * when the core only sees one. The FIFO receives the read which is cancelled,
+ * and not delivered to the core.
+ *
+ * To solve this, interrupts are turned off before reads occur to I/O space.
+ * There are 3 versions of all these functions
+ *  - turns interrupts off every read (higher overhead, but lower latency)
+ *  - turns interrupts off every loop (low overhead, but longer latency)
+ *  - DMA version, which do not suffer from this issue. DMA versions have
+ *      different name (prefixed by dma_ ), and are located in
+ *      ../kernel/bfin_dma_5xx.c
+ * Using the dma related functions are recommended for transfering large
+ * buffers in/out of FIFOs.

+/* Core file format: The core file is written in such a way that gdb
+   can understand it and provide useful information to the user (under
+   linux we use the 'trad-core' bfd).  There are quite a number of
+   obstacles to being able to view the contents of the floating point
+   registers, and until these are solved you will not be able to view the
+   contents of them.  Actually, you can read in the core file and look at
+   the contents of the user struct to find out what the floating point
+   registers contain.
+   The actual file contents are as follows:
+   UPAGE: 1 page consisting of a user struct that tells gdb what is present
+   in the file.  Directly after this is a copy of the task_struct, which
+   is currently not used by gdb, but it may come in useful at some point.
+   All of the registers are stored as part of the upage.  The upage should
+   always be only one page.
+   DATA: The data area is stored.  We use current->end_text to
+   current->brk to pick up all of the user variables, plus any memory
+   that may have been malloced.  No attempt is made to determine if a page
+   is demand-zero or if a page is totally unused, we just cover the entire
+   range.  All of the addresses are rounded in such a way that an integral
+   number of pages is written.
+   STACK: We need the stack information in order to get a meaningful
+   backtrace.  We need to write the data from (esp) to
+   current->start_stack, so we round each of these off in order to be able
+   to write an integer number of pages.
+   The minimum core file size is 3 pages, or 12288 bytes.
