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!

+ * ALI M14xx chipset EIDE controller
+ *
+ * Works for ALI M1439/1443/1445/1487/1489 chipsets.
+ *
+ * Adapted from code developed by derekn@vw.ece.cmu.edu.  -ml
+ * Derek's notes follow:
+ *
+ * I think the code should be pretty understandable,
+ * but I'll be happy to (try to) answer questions.
+ *
+ * The critical part is in the setupDrive function.  The initRegisters
+ * function doesn't seem to be necessary, but the DOS driver does it, so
+ * I threw it in.
+ *
+ * I've only tested this on my system, which only has one disk.  I posted
+ * it to comp.sys.linux.hardware, so maybe some other people will try it
+ * out.
+ *
+ * Derek Noonburg  (derekn@ece.cmu.edu)
+ * 95-sep-26
+ *
+ * Update 96-jul-13:
+ *
+ * I've since upgraded to two disks and a CD-ROM, with no trouble, and
+ * I've also heard from several others who have used it successfully.
+ * This driver appears to work with both the 1443/1445 and the 1487/1489
+ * chipsets.  I've added support for PIO mode 4 for the 1487.  This
+ * seems to work just fine on the 1443 also, although I'm not sure it's
+ * advertised as supporting mode 4.  (I've been running a WDC AC21200 in
+ * mode 4 for a while now with no trouble.)  -Derek

+ * From: andy@cercle.cts.com (Dyan Wile)
+ *
+ * Below is a patch for DTC-2278 - alike software-programmable controllers
+ * The code enables the secondary IDE controller and the PIO4 (3?) timings on
+ * the primary (EIDE). You may probably have to enable the 32-bit support to
+ * get the full speed. You better get the disk interrupts disabled ( hdparm -u0
+ * /dev/hd.. ) for the drives connected to the EIDE interface. (I get my
+ * filesystem  corrupted with -u1, but under heavy disk load only :-)
+ *
+ * This card is now forced to use the "serialize" feature,
+ * and irq-unmasking is disallowed.  If io_32bit is enabled,
+ * it must be done for BOTH drives on each interface.
+ *
+ * This code was written for the DTC2278E, but might work with any of these:
+ *
+ * DTC2278S has only a single IDE interface.
+ * DTC2278D has two IDE interfaces and is otherwise identical to the S version.
+ * DTC2278E also has serial ports and a printer port
+ * DTC2278EB: has onboard BIOS, and "works like a charm" -- Kent Bradford <kent@theory.caltech.edu>
+ *
+ * There may be a fourth controller type. The S and D versions use the
+ * Winbond chip, and I think the E version does also.

+ * This is the low-level hd interrupt support. It traverses the

+ * all the functions are called within interrupts, we may not
+ * sleep. Special care is recommended.
+ *
+ *  modified by Drew Eckhardt to check nr of hd's from the CMOS.
+ *
+ *  Thanks to Branko Lankester, lankeste@fwi.uva.nl, who found a bug

+ *
+ *  IRQ-unmask, drive-id, multiple-mode, support for ">16 heads",
+ *  and general streamlining by Mark Lord.
+ *
+ *  Removed 99% of above. Use Mark's ide driver for those options.
+ *  This is now a lightweight ST-506 driver. (Paul Gortmaker)
+ *
+ *  Modified 1995 Russell King for ARM processor.

+ * ht6560b Timing values:
+ *
+ * I reviewed some assembler source listings of htide drivers and found
+ * out how they setup those cycle time interfacing values, as they at Holtek
+ * call them. IDESETUP.COM that is supplied with the drivers figures out
+ * optimal values and fetches those values to drivers. I found out that
+ * they use IDE_SELECT_REG to fetch timings to the ide board right after
+ * interface switching. After that it was quite easy to add code to
+ * ht6560b.c.
+ *
+ * IDESETUP.COM gave me values 0x24, 0x45, 0xaa, 0xff that worked fine
+ * for hda and hdc. But hdb needed higher values to work, so I guess
+ * that sometimes it is necessary to give higher value than IDESETUP
+ * gives.   [see cmd640.c for an extreme example of this. -ml]
+ *
+ * Perhaps I should explain something about these timing values:
+ * The higher nibble of value is the Recovery Time  (rt) and the lower nibble
+ * of the value is the Active Time  (at). Minimum value 2 is the fastest and
+ * the maximum value 15 is the slowest. Default values should be 15 for both.
+ * So 0x24 means 2 for rt and 4 for at. Each of the drives should have
+ * both values, and IDESETUP gives automatically rt=15 st=15 for CDROMs or
+ * similar. If value is too small there will be all sorts of failures.
+ *
+ * Timing byte consists of
+ *	High nibble:  Recovery Cycle Time  (rt)
+ *	     The valid values range from 2 to 15. The default is 15.
+ *
+ *	Low nibble:   Active Cycle Time	   (at)
+ *	     The valid values range from 2 to 15. The default is 15.
+ *
+ * You can obtain optimized timing values by running Holtek IDESETUP.COM
+ * for DOS. DOS drivers get their timing values from command line, where
+ * the first value is the Recovery Time and the second value is the
+ * Active Time for each drive. Smaller value gives higher speed.
+ * In case of failures you should probably fall back to a higher value.

+ *  Version 0.05	replace sti() with restore_flags()  -ml
