Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+/* Dreamcast System ASIC Hardware Events -
+
+   The Dreamcast's System ASIC (a.k.a. Holly) is responsible for receiving
+   hardware events from system peripherals and triggering an SH7750 IRQ.
+   Hardware events can trigger IRQs 13, 11, or 9 depending on which bits are
+   set in the Event Mask Registers (EMRs).  When a hardware event is
+   triggered, it's corresponding bit in the Event Status Registers (ESRs)
+   is set, and that bit should be rewritten to the ESR to acknowledge that
+   event.
+
+   There are three 32-bit ESRs located at 0xa05f8900 - 0xa05f6908.  Event
+   types can be found in include/asm-sh/dc_sysasic.h.  There are three groups
+   of EMRs that parallel the ESRs.  Each EMR group corresponds to an IRQ, so
+   0xa05f6910 - 0xa05f6918 triggers IRQ 13, 0xa05f6920 - 0xa05f6928 triggers
+   IRQ 11, and 0xa05f6930 - 0xa05f6938 triggers IRQ 9.
+
+   In the kernel, these events are mapped to virtual IRQs so that drivers can
+   respond to them as they would a normal interrupt.  In order to keep this
+   mapping simple, the events are mapped as:
+
+   6900/6910 - Events  0-31, IRQ 13
+   6904/6924 - Events 32-63, IRQ 11
+   6908/6938 - Events 64-95, IRQ  9

+/*
+ * A brief note about the reasons for this API as it stands.
+ *
+ * For starters, the old ISA DMA API didn't work for us for a number of
+ * reasons, for one, the vast majority of channels on the SH DMAC are
+ * dual-address mode only, and both the new and the old DMA APIs are after the
+ * concept of managing a DMA buffer, which doesn't overly fit this model very
+ * well. In addition to which, the new API is largely geared at IOMMUs and
+ * GARTs, and doesn't even support the channel notion very well.
+ *
+ * The other thing that's a marginal issue, is the sheer number of random DMA
+ * engines that are present (ie, in boards like the Dreamcast), some of which
+ * cascade off of the SH DMAC, and others do not. As such, there was a real
+ * need for a scalable subsystem that could deal with both single and
+ * dual-address mode usage, in addition to interoperating with cascaded DMACs.
+ *
+ * There really isn't any reason why this needs to be SH specific, though I'm
+ * not aware of too many other processors (with the exception of some MIPS)
+ * that have the same concept of a dual address mode, or any real desire to
+ * actually make use of the DMAC even if such a subsystem were exposed
+ * elsewhere.
+ *
+ * The idea for this was derived from the ARM port, which acted as an excellent
+ * reference when trying to address these issues.
+ *
+ * It should also be noted that the decision to add Yet Another DMA API(tm) to
+ * the kernel wasn't made easily, and was only decided upon after conferring
+ * with jejb with regards to the state of the old and new APIs as they applied
+ * to these circumstances. Philip Blundell was also a great help in figuring
+ * out some single-address mode DMA semantics that were otherwise rather
+ * confusing.

+config PCI
+	bool "PCI support"
+	help
+	  Find out whether you have a PCI motherboard. PCI is the name of a
+	  bus system, i.e. the way the CPU talks to the other stuff inside
+	  your box. If you have PCI, say Y, otherwise N.
+
+	  The PCI-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>, contains valuable
+	  information about which PCI hardware does work under Linux and which
+	  doesn't.
+
+config SH_PCIDMA_NONCOHERENT
+	bool "Cache and PCI noncoherent"
+	depends on PCI
+	default y
+	help
+	  Enable this option if your platform does not have a CPU cache which
+	  remains coherent with PCI DMA. It is safest to say 'Y', although you
+	  will see better performance if you can say 'N', because the PCI DMA
+	  code will not have to flush the CPU's caches. If you have a PCI host
+	  bridge integrated with your SH CPU, refer carefully to the chip specs
+	  to see if you can say 'N' here. Otherwise, leave it as 'Y'.
+
+# This is also board-specific
+config PCI_AUTO
+	bool
+	depends on PCI
+	default y
+
+config PCI_AUTO_UPDATE_RESOURCES
+	bool
+	depends on PCI_AUTO
+	default y if !SH_DREAMCAST
+	help
+	  Selecting this option will cause the PCI auto code to leave your
+	  BAR values alone. Otherwise they will be updated automatically. If
+	  for some reason, you have a board that simply refuses to work
+	  with its resources updated beyond what they are when the device
+	  is powered up, set this to N. Everyone else will want this as Y.

+ * Minor modifications by Jeremy Siegel <jsiegel@mvista.com>
+ * 
+ * Contains low-level support for remote debug using GDB. 
+ *
+ * To enable debugger support, two things need to happen. A call to
+ * set_debug_traps() is necessary in order to allow any breakpoints
+ * or error conditions to be properly intercepted and reported to gdb.
+ * A breakpoint also needs to be generated to begin communication.  This
+ * is most easily accomplished by a call to breakpoint() which does
+ * a trapa if the initialisation phase has been successfully completed.
+ *
+ * In this case, set_debug_traps() is not used to "take over" exceptions;
+ * other kernel code is modified instead to enter the kgdb functions here
+ * when appropriate (see entry.S for breakpoint traps and NMI interrupts,
+ * see traps.c for kernel error exceptions).
+ *
+ * The following gdb commands are supported:
+ *
+ *    Command       Function                               Return value
+ *
+ *    g             return the value of the CPU registers  hex data or ENN
+ *    G             set the value of the CPU registers     OK or ENN
+ *
+ *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
+ *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
+ *    XAA..AA,LLLL: Same, but data is binary (not hex)     OK or ENN

+ * Remote communication protocol.
+ *
+ *    A debug packet whose contents are <data> is encapsulated for
+ *    transmission in the form:
+ *
+ *       $ <data> # CSUM1 CSUM2
+ *
+ *       <data> must be ASCII alphanumeric and cannot include characters
+ *       '$' or '#'.  If <data> starts with two characters followed by
+ *       ':', then the existing stubs interpret this as a sequence number.
+ *
+ *       CSUM1 and CSUM2 are ascii hex representation of an 8-bit 
+ *       checksum of <data>, the most significant nibble is sent first.
+ *       the hex digits 0-9,a-f are used.
+ *
+ *    Receiver responds with:
+ *
+ *       +       - if CSUM is correct and ready for next packet
+ *       -       - if CSUM is incorrect
+ *
+ * Responses can be run-length encoded to save space.  A '*' means that
+ * the next character is an ASCII encoding giving a repeat count which
+ * stands for that many repititions of the character preceding the '*'.
+ * The encoding is n+29, yielding a printable character where n >=3 
+ * (which is where RLE starts to win).  Don't use an n > 126. 
+ *
+ * So "0* " means the same as "0000".
