Linux-2.6.12-rc2v2.6.12-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!

7 | * | ||
8 | * Thanks to HighPoint Technologies for their assistance, and hardware. | ||
9 | * Special Thanks to Jon Burchmore in SanDiego for the deep pockets, his | ||
10 | * donation of an ABit BP6 mainboard, processor, and memory acellerated | ||
11 | * development and support. | ||
12 | * | ||
13 | * Note that final HPT370 support was done by force extraction of GPL. | ||
14 | * | ||
15 | * - add function for getting/setting power status of drive | ||
16 | * - the HPT370's state machine can get confused. reset it before each dma | ||
17 | * xfer to prevent that from happening. | ||
18 | * - reset state engine whenever we get an error. | ||
19 | * - check for busmaster state at end of dma. | ||
20 | * - use new highpoint timings. | ||
21 | * - detect bus speed using highpoint register. | ||
22 | * - use pll if we don't have a clock table. added a 66MHz table that's | ||
23 | * just 2x the 33MHz table. | ||
24 | * - removed turnaround. NOTE: we never want to switch between pll and | ||
25 | * pci clocks as the chip can glitch in those cases. the highpoint | ||
26 | * approved workaround slows everything down too much to be useful. in | ||
27 | * addition, we would have to serialize access to each chip. | ||
28 | * Adrian Sun <a.sun@sun.com> | ||
29 | * | ||
30 | * add drive timings for 66MHz PCI bus, | ||
31 | * fix ATA Cable signal detection, fix incorrect /proc info | ||
32 | * add /proc display for per-drive PIO/DMA/UDMA mode and | ||
33 | * per-channel ATA-33/66 Cable detect. | ||
34 | * Duncan Laurie <void@sun.com> | ||
35 | * | ||
36 | * fixup /proc output for multiple controllers | ||
37 | * Tim Hockin <thockin@sun.com> | ||
38 | * | ||
39 | * On hpt366: | ||
40 | * Reset the hpt366 on error, reset on dma | ||
41 | * Fix disabling Fast Interrupt hpt366. | ||
42 | * Mike Waychison <crlf@sun.com> | ||
43 | * | ||
44 | * Added support for 372N clocking and clock switching. The 372N needs | ||
45 | * different clocks on read/write. This requires overloading rw_disk and | ||
46 | * other deeply crazy things. Thanks to <http://www.hoerstreich.de> for | ||
47 | * keeping me sane. | ||
