[patch 2.6.1] Silicon Image 3512 SATA Controller - Tested

[Aron Rubin <arubin@atl.lmco.com>]

[-- Attachment #1: Type: text/plain, Size: 980 bytes --]

This patch enables the Silicon Image 3512 SATA Controller and has been 
tested and functioning without any apparent bugs (I do not have a full 
test suite but I am not booting off a device attached to this 
controller). This patch is against the Dave Jones 2.6.1-1.34 kernel 
source rpm.

You may remember I was trying to get help on this chipset before. My 
patch is simply a duplicate of the entries for the 3112 chipset. It did 
not work fully with prior kernels, giving me a "Interrupt Lost" errors. 
Whatever else was done to 2.6.1 had made it happy again. Also I did not 
have to use any special commandline options.
