2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.

2014-02-25Remove CACHE_ROM.Vladimir Serbinenko
With the recent improvement 3d6ffe76f8a505c2dff5d5c6146da3d63dad6e82, speedup by CACHE_ROM is reduced a lot. On the other hand this makes coreboot run out of MTRRs depending on system configuration, hence screwing up I/O access and cache coherency in worst cases. CACHE_ROM requires the user to sanity check their boot output because the feature is brittle. The working configuration is dependent on I/O hole size, ram size, and chipset. Because of this the current implementation can leave a system configured in an inconsistent state leading to unexpected results such as poor performance and/or inconsistent cache-coherency Remove this as a buggy feature until we figure out how to do it properly if necessary.

2014-02-11baytrail: set max frequency early in romstageAaron Durbin
Set the BSP to operate at max frequency early in romstage. The call to punit_init() is when the frequency actually ramps as that makes the punit actually start working. BUG=chrome-os-partner:22857 BRANCH=None TEST=Built and booted. Noted operating frequency status is max.

2014-02-11baytrail: adjust cache policy during romstageAaron Durbin
The caching policy for romstage was previously using a 32KiB of cache-as-ram for both the MRC wrapper and the romstage stack/data. It also used a 32KiB code cache region. The BWG's limitations for the code and data region before memory is up was wrong. It consists of a 16-way set associative 1MiB cache. As long as enough addresses are not read there isn't a risk of evicting the data/stack. Now create a 64KiB cache-as-ram region split evenly between romstage and the MRC wrapper. Additionally cache the memory just below 4GiB in CBFS size. This will cover any code and read-only data needed. BUG=chrome-os-partner:22858 BRANCH=None TEST=Built and booted quickly with corresponding changes to MRC warpper.

2014-02-05baytrail: initialize punitAaron Durbin
The punit is responsible for a number of things. Without performing the sequence included it won't change processor frequency when requested and apparently there are some bizarre hangs introduced if this sequence isn't included either. Lastly, this needs to come after microcode has been loaded. As that is done in bootblock the ordering is correct. One other side effect is that this fixes the graphics devices' device id. Before it was showing up as the same device id of the SoC transaction router. BUG=chrome-os-partner:22880 BUG=chrome-os-partner:23085 BUG=chrome-os-partner:22876 BRANCH=None TEST=Built and booted.

2014-02-05baytrail: disable tco timerAaron Durbin
The TCO timer always starts ticking out of reset. However, depending on microcode loading and punit initialization the TCO timing out has a different impact on the sytem. Without loading microcode or initializing the punit the tco times out and nothing happens. However, when microcode is loaded a timeout will reset the system. Lastly, if the punit is initialized but the microcode isn't loaded the TCO timeout will shut down the system. To fix all the weird symptoms disable the TCO.
