+ * ncr53c8xx.c ncr53c8xx.h revision 1.18b
+ - 'On paper' support of the NCR53C895 Ultra-2 chip.
+ (Clock quadrupler + 7 clock divisors)
+ - Load the main part of the script into the on-board RAM.
+ - 810A rev. 0x11 PCI problem fixed.
+ This chip is now supported with all PCI features enabled and
+ 16 dwords burst transfers.
+ - Align on 32 boundary some internal structures.
+ That fixes the 810A problem and allows cache line bursting when
+ moving the global header (64 bytes) from/to CCBs to/from NCB.
+ - Synchronous parameters calculation rewritten. The driver
+ now uses all available clock divisors and will be able to support
+ clock frequencies that are not multiple of 40 Mhz if necessary.

+ * ncr53c8xx.c - revision 1.17a
+ - IRQ mode set up from boot setup command.
+ irqm:0 open drain (default)
+ irqm:1 preserve initial setting (assumed from BIOS)
+ irqm:2 totem pole
+ - DIFF mode set up from boot setup command.
+ Suggested by Richard Waltham.
+ diff:0 never set up diff mode (default)
+ diff:1 set up diff mode according to initial setting (BIOS?)
+ diff:2 always set up diff mode
+ diff:3 set up diff mode if GPIO3 is zero (SYMBIOS boards)
+ - Change CONFIG option for LED support.
+ CONFIG_SCSI_NCR53C8XX_SYMBIOS_COMPAT allows LED support and
+ DIFF support for SYMBIOS boards and compatibles (clones?).
+ - Set 16 DWORD bursts for 810A rev. >= 0x12 since my SC200 with
+ such a chip have no problem with it (MB with Triton 2 HX).
+ 810A rev. 0x11 are set to 8 DWORD bursts since they may give
+ problems with PCI read multiple and Triton 2 HX.
+ Thanks to Stefan for this information.

+ * ncr53c8xx.c - revision 1.17
+ - Controller LED support.
+ Only works with LED pin wired to GPIO_FETCHN, so probably with
+ all boards using SMDS BIOS.
+ This option can be enabled only if CONFIG_EXPERIMENTAL is set.
+ - Assume clock doubler for 875 chip when clock frequency measurement
+ result is 40 MHz. May help when some old stuff as SDMS BIOS 3.0
+ or some old driver has broken the normal BIOS settings.
+ - Add wide negotiation control from boot setup command.
+ May be usefull with systems using a 875 based board connected to
+ a wide device through a 50 pins to 68 pins converter.
+ - Add a "boot fail safe option" to the boot setup command line.
+ - Rewrite the "reset_command" routine.
+ Low-level driver are responsible to keep the involved command
+ alive. The new code seems to behave correctly.
+ - Change some variables used by the script from u_long to u_int32.
+ - Remove some useless code.

* ncr53c8xx.c - revision 1.16e
- Add support of PCI burst length control from boot setup command.
