2013-03-22Unify coreboot table generationStefan Reinauer
coreboot tables are, unlike general system tables, a platform independent concept. Hence, use the same code for coreboot table generation on all platforms. lib/coreboot_tables.c is based on the x86 version of the file, because some important fixes were missed on the ARMv7 version lately.

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

2013-03-20link/graphics: Add support for EDIDRonald G. Minnich
This code is taken from an EDID reader written at Red Hat. The key function is int decode_edid(unsigned char *edid, int size, struct edid *out) Which takes a pointer to an EDID blob, and a size, and decodes it into a machine-independent format in out, which may be used for driving chipsets. The EDID blob might come for IO, or a compiled-in EDID BLOB, or CBFS. Also included are the changes needed to use the EDID code on Link.

2013-03-20link/graphics: New state machineRonald G. Minnich
This is a new state machine. It is more programmatic, in the case of auxio, and has much more symbolic naming, and very few "magic" numbers, except in the case of undocumented settings. As before, the 'pre-computed' IO ops are encoded in the iodefs table. A function, run, is passed and index into the table and runs the ops. A new operator, I, has been added. When the I operator is hit, run() returns the index of the next operator in the table. The i915lightup function runs the table. All the AUX channel ops have been removed from the table, however, and are now called as functions, using the previously committed auxio function. The iodefs table has been grouped into blocks of ops, which end in an I operator. As the lightup function progresses through startup, and the run() returns, the lightup function performs aux channel operations. This code is symbolic enough, I hope, that it will make haswell graphics bringup simpler. i915io.c, and the core of the code in i915lightup.c, were programatically generated, starting with IO logs from the DRM startup code in the kernel. It is possible to apply the tools that do this generation to newer IO logs from the kernel. Change-Id: I8a8e121dc0d9674f0c6a866343b28e179a1e3d8a Signed-off-by: Ronald G.

2013-03-20link/graphics: implement a palette setting operatorRonald G. Minnich
Add a new operator, P, for the state machine, meaning implement a palette fill. Implement a function (palette) that fills the palette when the P operator is hit. This replaces 256 lines in the state machine table with 1. Change-Id: I67d9219fe7de0ecf1fb9faf92130c00c9f5f8e88 Signed-off-by: Ronald G.

2013-03-19link/graphics: add functions to support aux channel communicationsRonald G. Minnich
For full integration of FUI into coreboot, we need aux channel communcations. The intel_dp.c is a file taken from Linux and is used for aux channel comms. This file has been cut down to work with coreboot. For now it is associated with the link mainboard until we get a better handle on how this all fits together. This code is almost certainly usable on other platforms in the long term. But one step at a time. Change-Id: I7be4c56e0a7903f3901ac86e12b28f3bdc0f7947 Signed-off-by: Ronald G.

2013-03-13src/mainboard: Drop redundant `CHIP_NAME` again for new portsPaul Menzel
Since commit »Drop redundant CHIP_NAME in mainboard.c« (a93c3fe7) [1] `CHIP_NAME` is unneeded for mainboards as the name is composed automatically in `src/devices/root_device.c` from the strings in Kconfig. Unfortunately the ports for Google Butterfly, Link and Parrot as as well as IEI PM-LX2-800-R10 introduced CHIP_NAME again. So drop it again too.
