At the same time also make the 82810 code handle 82810E.
- Set SMRAM register according to CONFIG_VIDEO_MB value:
- 512 means 512 KB
- 1 means 1 MB
- Every other value for CONFIG_VIDEO_MB (e.g. 0) disables VGA.
This is not very clean, changing CONFIG_VIDEO_MB to CONFIG_VIDEO_KB
in a future patch may be nicer.
- Set MISSC2 register bits as required per datasheet to make VGA work.
The code handles both 82810 and 82810E.
- northbridge.c: Add __pci_driver entry for the Intel 82810E.
Also:
- Rename PAM register #define to PAMR as per datasheet.
- Drop unused/commented code for now.
- Don't explicitly set GMCHCFG for now, the default works ok. We'll
have to figure out the proper/ideal settings later.
The code is based on a patch from Elia Yehuda <z4ziggy@gmail.com> but
has been modified quite a bit for correctness and minimalism.
Tested on hardware with a slightly modified MS-6178 target,
patches to enable onboard-VGA for MS-6178 will follow.

------------------------------------------------------------------------------- coreboot README ------------------------------------------------------------------------------- coreboot is a Free Software project aimed at replacing the proprietary BIOS you can find in most of today's computers. It performs just a little bit of hardware initialization and then executes one of many possible payloads, e.g. a Linux kernel or a bootloader. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot. See http://www.coreboot.org/Payloads for a list of supported payloads. Supported Hardware ------------------ coreboot supports a wide range of chipsets, devices, and mainboards. For details please consult: * http://www.coreboot.org/Supported_Motherboards * http://www.coreboot.org/Supported_Chipsets_and_Devices Build Requirements ------------------ * gcc / g++ * make * python * perl Optional: * doxygen (for generating/viewing documentation) * iasl (for targets with ACPI support) * gdb (for better debugging facilities on some targets) Building coreboot ----------------- Please consult http://www.coreboot.org/Documentation for details. Testing coreboot Without Modifying Your Hardware ------------------------------------------------- If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU. Please see http://www.coreboot.org/QEMU for details. Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
