^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   6)  *	The Opti DMA controllers are related to the older PIO PCI controllers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   7)  *	and indeed the VLB ones. The main differences are that the timing
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   8)  *	numbers are now based off PCI clocks not VLB and differ, and that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   9)  *	MWDMA is supported.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  10)  *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  11)  *	This driver should support Viper-N+, FireStar, FireStar Plus.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  13)  *	These devices support virtual DMA for read (aka the CS5520). Later
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  14)  *	chips support UDMA33, but only if the rest of the board logic does,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  15)  *	so you have to get this right. We don't support the virtual DMA
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  16)  *	but we do handle UDMA.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  17)  *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  18)  *	Bits that are worth knowing
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  19)  *		Most control registers are shadowed into I/O registers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  20)  *		0x1F5 bit 0 tells you if the PCI/VLB clock is 33 or 25Mhz
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  21)  *		Virtual DMA registers *move* between rev 0x02 and rev 0x10
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  22)  *		UDMA requires a 66MHz FSB
