Author: stepan Date: Mon Mar 1 09:34:19 2010 New Revision: 5177 URL: http://tracker.coreboot.org/trac/coreboot/changeset/5177 Log: This patch implements MBI (modular bios interface) support to the i830 chipset. This is needed on the IP1000T to get VGA output. The VGA option rom will ask through an SMI for hardware specifics (in form of a VBT, video bios table) which the SMI handler copies into the VGA option rom.

[PATCH]generic ssdt rules
by Patrick Georgi 28 Feb '10

28 Feb '10

Hi, attached patch unifies the ACPI_SSDTX_NUM handling. - define meaning for ACPI_SSDTX_NUM: highest ssdtX.asl to build - add rules that build either 4 or 5 ssdts (which is what exists in the tree now) - change ACPI_SSDTX_NUM to either 4 or 5 for boards that have ssdtX.asl files, according to the ssdtX.asl in there. - remove custom ssdt rules I checked the tree and didn't find any occurrence where the value of ACPI_SSDTX_NUM was used for something else than a test for >= 1, so changing the values (within this constraint) won't affect behaviour. No idea what "31" was supposed to be good for, but it definitely doesn't affect the build. There is no simple way to do "greater than" tests in gnu make that I found. One solution would be some recursive macro that adds ssdtX rules for x down to 2 (ssdt1 doesn't exist by convention), which seems to require building mathematical functions first, etc. That seemed to be overkill for the three uses of the variable (which isn't even globally defined) Signed-off-by: Patrick Georgi <patrick.georgi(a)coresystems.de>
