2001-09-21	Correct some pryntf() usage: get the correct number of arguments in the	Miod Vallat
	correct order.
2001-07-12	Rework of probe code. Try better to deal with floating buses. Depending	Constantine Sapuntzakis
	on the value floating on the bus, we would occasionally skip the register writability tests. Whoops... Move fix for a flash device that doesn't wake up until a command is sent Try to supress spurious interrupts. However, if one does happen, acknowledge it anyway by reading status. This prevents the interrupt condition from persisting.
2001-07-09	ch_flags should be ch_status	Constantine Sapuntzakis

2001-03-25	Minor mods to DMA interface - get rid of unnecessary args. Allow DMA ↵	Constantine Sapuntzakis
	functions to return status flags. Note: Changing code to have DMA interface indicate when I/O is done (a la NetBSD) was considered. It was rejected due to questionable backward compatability with ISA DMA and MAC obio DMA Added irqack from NetBSD (though this feature should really be in the PCI interrupt handlers) Use pool
2001-01-29	Fix bug where timeouts triggered too early, caused panic on ATAPI tapes.	Niklas Hallqvist
	Removed hardcoded WDCDEBUG definitions.
2000-10-29	undo this; adds files, unacceptable at this point in release	Theo de Raadt

2000-10-28	Reduce footprint of ATA driver by only having PROBE debug messages compiled	Constantine Sapuntzakis
	in by default.
2000-07-20	Fix to ATA detect. Some devices seem to be comatose after reset	Constantine Sapuntzakis
	(return 0x00 status persistently). Send them identify to wake them up. Flag value 0x10000 will enable probe messages for a channel/controller. When UKC supports setting flags, this will be useful debugging failing IDE detects without kernel recompiles.
2000-04-07	correct debug printouts	Niklas Hallqvist

1999-11-17	New interface to ATA registers that goes through the lower-level device	Constantine Sapuntzakis
	driver (pciide, wdc, etc.) Remove #define WDCDEBUG from top of files More fixes to ATAPISCSI logic: Not all devices transition correctly between phases. Devices are supposed to keep BSY high until they've set the registers to the next sensible state. Some devices drop BSY and leave the registers in an old or nonsense state. Our polling code is extremely sensitive to this (though an early itnerrupt could also observe this). So, if the device is in an unexpected state, the new polling code waits for a while in the hope that it enters a better state. This seems to fix many of the problems reported. Also, there was a horrible bug which would cause sense to fail on a ATAPI command that sent data to the drive
1999-11-05	Fix ata_get_params on big endian platforms.	Constantine Sapuntzakis
	We have diverged from NetBSD in that wdc_exec_xfer no longer automatically swaps.
1999-08-05	Make IDE compile on alpha again:	Niklas Hallqvist
	use b* instead of mem* functions, adhere to NISADMA for DMA support.
1999-07-18	Import of NetBSD ATA/IDE stuff.	Constantine Sapuntzakis
	Introduction of home-grown To enable this stuff in your configuration, look at the NEWATA conf file and go through dev/isa/files.isa dev/pci/files.pci conf/files arch/i386/conf/files.i386 and follow the instructions on commenting/uncommenting stuff
