2011-09-14rs780: hide unused gfx ports and gpp portsKerry Sheh
Hide the unused gfx ports and gpp ports if they are not configured as hotplug. lspci -vvv will get more accurate information under Linux, tested on avalue/eax-785e.

2010-12-08first round name simplification. drop the <component>_ prefix.stepan
the prefix was introduced in the early v2 tree many years ago because our old build system "newconfig" could not handle two files with the same name in different paths like /path/to/usb.c and /another/path/to/usb.c correctly. Only one of the files would end up being compiled into the final image. Since Kconfig (actually since shortly before we switched to Kconfig) we don't suffer from that problem anymore. So we could drop the sb700_ prefix from all those filenames (or, the <componentname>_ prefix in general) - makes it easier to fork off a new chipset - makes it easier to diff against other chipsets - storing redundant information in filenames seems wrong Signed-off-by: <stepan@coresystems.de> Acked-by: Patrick Georgi <patrick@georgi-clan.de> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6149 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2010-11-24This patch solves crashes and BSODs that occur when booting Win7 withScott Duplichan
AMD RS780 uma graphics. Tested with frame buffer sizes 64m through 1GB by running dxdiag and Windows media player at 1600x1200 true color. Additional changes needed to boot Win7 on Mahogany_fam10 will follow. -- Enable and program the debug bar as required by the ATI graphics driver. First, make the debug bar writable and allow resource allocation code to program it. Once programmed, enable its operation. -- Disable the family 10h processor mmconf while the RS780 mmconf is in use. -- Make strap programming more closely follow the reference BIOS. -- Disable PCIe bar 3 after using it. -- UMA size is no longer hardcoded. -- Disable write combining for all steppings to eliminate stability problem. -- Correct task file data. -- Improve the accuracy of the Atom table that passes information to the driver.

2010-03-16Features supported in RS780 code:Zheng Bao
* 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.
