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!

15 * GIO bus addresses
16 *
17 * The Indigo and Indy have two GIO bus connectors. Indigo2 (all models) have
18 * three physical connectors, but only two slots, GFX and EXP0.
19 *
20 * There is 10MB of GIO address space for GIO64 slot devices
21 * slot# slot type address range size
22 * ----- --------- ----------------------- -----
23 * 0 GFX 0x1f000000 - 0x1f3fffff 4MB
24 * 1 EXP0 0x1f400000 - 0x1f5fffff 2MB
25 * 2 EXP1 0x1f600000 - 0x1f9fffff 4MB
26 *
27 * There are un-slotted devices, HPC, I/O and misc devices, which are grouped
28 * into the HPC address space.
29 * - MISC 0x1fb00000 - 0x1fbfffff 1MB
30 *
31 * Following space is reserved and unused
32 * - RESERVED 0x18000000 - 0x1effffff 112MB
33 *
34 * GIO bus IDs
35 *
36 * Each GIO bus device identifies itself to the system by answering a
37 * read with an "ID" value. IDs are either 8 or 32 bits long. IDs less
38 * than 128 are 8 bits long, with the most significant 24 bits read from
39 * the slot undefined.
40 *
41 * 32-bit IDs are divided into
42 * bits 0:6 the product ID; ranges from 0x00 to 0x7F.
43 * bit 7 0=GIO Product ID is 8 bits wide
44 * 1=GIO Product ID is 32 bits wide.
45 * bits 8:15 manufacturer version for the product.
46 * bit 16 0=GIO32 and GIO32-bis, 1=GIO64.
47 * bit 17 0=no ROM present
48 * 1=ROM present on this board AND next three words
49 * space define the ROM.
50 * bits 18:31 up to manufacturer.
51 *
52 * IDs above 0x50/0xd0 are of 3rd party boards.
