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.
