New SYM-2 driver version for Linux-2.4.19

New SYM-2 driver version for Linux-2.4.19

[Gérard Roudier]

Hello,

I just made available my current version of the sym53c8xx_2 driver for
Linux. I have merged the changes from linux 2.4.19 and 2.5.45.

ftp://ftp.tux.org/pub/roudier/drivers/linux/stable/sym-2.1.19-pre3-for-linux-2.4.19.tar.gz

(Not sure the URL is full correct, but it shouldn't this wrong... :-))

There is also some code from me that has been added. ;)
Here is the ChangeLog addition:

	- Merge changes from linux-2.4.19 and linux-2.5.45.
	  Rearrange the code for the source to compile and run on both
	  Linux versions + some rewrites for the code to look good to me ;).
	- Add enough #if's for the smp locking to be source compatible for
	  both Linux branches.
	- Move all the nvram related definitions to a separate header file
	  and add the code that allows to write to the NVRAM.
	- Rearrange the code in function sym_snooptest().
	- Test against DMA ressource shortage and return error condition
	  if such happens (the scatter code has been slightly rewritten).
	- Add a new  errata work-around for all C10*0 chips (SCNTL3 register
	  must not be altered when REQs occurs on the SCSI BUS).
	  A copy of the 'select' table (alt_sel) has been added in the CCB
	  for this work-around.
	- A couple of minor changes + some typo fixes.

The code should also compile and run under Linux 2.5.45. I don't know for
now if it is compatible with any prior or further 2.5 branch kernel
version. I will resync with current linux SCSI as soon as I will have time
for.

You may let me know if you encounter problems with this new driver
version. Thanks.

  Gérard.
