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!

+ * staggered INTA-D lines, resulting in 8 lines total (PCI0 INTA-D and
+ * PCI1 INTA-D). All 8 go to the CPLD interrupt controller. PCI0 INTA-D
+ * also go to the south bridge, so we have the option of taking them
+ * via the CPLD interrupt controller or via the south bridge 8259
+ * 8258 thingy. PCI1 INTA-D can only be taken via the CPLD interrupt
+ * controller. We take all PCI interrupts via the CPLD interrupt
+ * controller as recommended by SBS.
+ *
+ * We also have some monkey business with the PCI devices within the
+ * VT82C686B south bridge itself. This chip actually has 7 functions on
+ * its IDSEL. Function 0 is the actual south bridge, function 1 is IDE,
+ * and function 4 is some special stuff. The other 4 functions are just
+ * regular PCI devices bundled in the chip. 2 and 3 are USB UHCIs and 5
+ * and 6 are audio (not supported on the Adirondack).
+ *
+ * This is where the monkey business begins. PCI devices are supposed
+ * to signal normal PCI interrupts. But the 4 functions in question are
+ * located in the south bridge chip, which is designed with the
+ * assumption that it will be fielding PCI INTA-D interrupts rather
+ * than generating them. Here's what it does. Each of the functions in
+ * question routes its interrupt to one of the IRQs on the 8259 thingy.
+ * Which one? It looks at the Interrupt Line register in the PCI config
+ * space, even though the PCI spec says it's for BIOS/OS interaction
+ * only.
+ *
+ * How do we deal with this? We take these interrupts via 8259 IRQs as
+ * we have to. We return the desired IRQ numbers from this routine when
+ * called for the functions in question. The PCI scan code will then
+ * stick our return value into the Interrupt Line register in the PCI
+ * config space, and the interrupt will actually go there. We identify
+ * these functions within the south bridge IDSEL by their interrupt pin
+ * numbers, as the VT82C686B has 04 in the Interrupt Pin register for
+ * USB and 03 for audio.

+/*
+ * This file adds support for the Motorola SPS Sandpoint Test Platform.
+ * These boards have a PPMC slot for the processor so any combination
+ * of cpu and host bridge can be attached. This port is for an 8240 PPMC
+ * module from Motorola SPS and other closely related cpu/host bridge
+ * combinations (e.g., 750/755/7400 with MPC107 host bridge).
+ * The sandpoint itself has a Windbond 83c553 (PCI-ISA bridge, 2 DMA ctlrs, 2
+ * cascaded 8259 interrupt ctlrs, 8254 Timer/Counter, and an IDE ctlr), a
+ * National 87308 (RTC, 2 UARTs, Keyboard & mouse ctlrs, and a floppy ctlr),
+ * and 4 PCI slots (only 2 of which are usable; the other 2 are keyed for 3.3V
+ * but are really 5V).
+ *
+ * The firmware on the sandpoint is called DINK (not my acronym :). This port
+ * depends on DINK to do some basic initialization (e.g., initialize the memory
+ * ctlr) and to ensure that the processor is using MAP B (CHRP map).
+ *
+ * The switch settings for the Sandpoint board MUST be as follows:
+ * S3: down
+ * S4: up
+ * S5: up
+ * S6: down
+ *
+ * 'down' is in the direction from the PCI slots towards the PPMC slot;
+ * 'up' is in the direction from the PPMC slot towards the PCI slots.
+ * Be careful, the way the sandpoint board is installed in XT chasses will
+ * make the directions reversed.
+ *
+ * Since Motorola listened to our suggestions for improvement, we now have
+ * the Sandpoint X3 board. All of the PCI slots are available, it uses
+ * the serial interrupt interface (just a hardware thing we need to
+ * configure properly).
+ *
+ * Use the default X3 switch settings. The interrupts are then:
+ * EPIC Source
+ * 0 SIOINT (8259, active low)
+ * 1 PCI #1
+ * 2 PCI #2
+ * 3 PCI #3
+ * 4 PCI #4
+ * 7 Winbond INTC (IDE interrupt)
+ * 8 Winbond INTD (IDE interrupt)
+ *
+ *
+ * Motorola has finally released a version of DINK32 that correctly
+ * (seemingly) initalizes the memory controller correctly, regardless
+ * of the amount of memory in the system. Once a method of determining
+ * what version of DINK initializes the system for us, if applicable, is
+ * found, we can hopefully stop hardcoding 32MB of RAM.
