From eff2ffdee8489f97b265b0335b766be3db9a633a Mon Sep 17 00:00:00 2001 From: Zheng Bao Date: Tue, 16 Mar 2010 01:38:54 +0000 Subject: Features supported in SB700 code: * SATA initialization. * USB initialization. * HDA initialization. * LPC initialization. * IDE initialization. * SMBUS initialization. Note: 1. I tried to add the description of every step to the code. For example, if it is made based on rpr, section 2.4.5, I will pasted the words from 2.4.5 to the c code. But the document I worked with might be different with the most updated one. A new section has been added and the 2.4.5 might be changed to 2.5.5. That migh lead to confusing. I correct every comment if I met one. But I have to confess that I am so reluctant to find out everyone. I believe it will be correct in the long run. 2. I only test the SATA port 0-3. The ports 4, 5 are "PATA emulations". I am confused about it. 3. This patch is not only about SB700. Actually it should be SB7x0. But I dont think it is nice to change everything to SB7x0. It is ugly, isn't it. As far as I know, they all use the same code with revision checking. If you guys think it is appropriate, please modify it to sb7x0.
