Author: zbao Date: Tue Mar 16 02:41:14 2010 New Revision: 5219 URL: https://tracker.coreboot.org/trac/coreboot/changeset/5219
Log: Features supported in RS780 code: * PCIe initialization. * Internal Graphics initialization. * HT Link initialization. It works in HT1 or HT3 mode.
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. The interanl graphics part is done by Libo Feng libo.feng@amd.com. 3. There is a conflict between RPR and our CIM code. Please see the comment in switching_gppsb_configurations in rs780_pcie.c.
