2014-05-22device/pci_ids.h: defines for new Intel LPC devicesMartin Roth
Add defines for the Cave Creek and Rangeley LPC devices. These chipsets will be added shortly. This file is outside of any of the directories that will be touched by those additions, so it's getting changed in its own commit.

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.

2014-03-20rmodules: use rmodtool to create rmodulesAaron Durbin
Start using the rmodtool for generating rmodules. rmodule_link() has been changed to create 2 rules: one for the passed in <name>, the other for creating <name>.rmod which is an ELF file in the format of an rmodule. Since the header is not compiled and linked together with an rmodule there needs to be a way of marking which symbol is the entry point. __rmodule_entry is the symbol used for knowing the entry point. There was a little churn in SMM modules to ensure an rmodule entry point symbol takes a single argument.

2014-03-11chromeos: provide option to dynamically allocate ram oops bufferAaron Durbin
Fixing the location of the ram oops buffer can lead to certain kernel and boot loaders being confused when there is a ram reservation low in the address space. Alternatively provide a mechanism to allocate the ram oops buffer in cbmem. As cbmem is usually high in the address space it avoids low reservation confusion. The patch uncondtionally provides a GOOG9999 ACPI device with a single memory resource describing the memory region used for the ramoops region. BUG=None BRANCH=baytrail,haswell TEST=Built and booted with and w/o dynamic ram oops. With the corresponding kernel change things behave correctly.

Boot speeds can be sped up by mirroring the payload into main memory before doing the actual loading. Systems that would benefit from this are typically Intel ones whose SPI are memory mapped. Without the SPI being cached all accesses to the payload in SPI while being loaded result in uncacheable accesses. Instead take advantage of the on-board SPI controller which has an internal cache and prefetcher by copying 64-byte cachelines using 32-bit word copies.

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.

2014-01-30x86: parallel MP initializationAaron Durbin
Provide a common entry point for bringing up the APs in parallel. This work is based off of the Haswell one which can be moved over to this in the future. The APs are brought up and have the BSP's MTRRs duplicated in their own MTRRs. Additionally, Microcode is loaded before enabling caching. However, the current microcode loading support assumes Intel's mechanism. The infrastructure provides a notion of a flight plan for the BSP and APs. This allows for flexibility in the order of operations for a given architecture/chip without providing any specific policy. Therefore, the chipset caller can provide the order that is required.

2014-01-16cpu/intel: Make all Intel CPUs load microcode from CBFSAlexandru Gagniuc
The sequence to inject microcode updates is virtually the same for all Intel CPUs. The same function is used to inject the update in both CBFS and hardcoded cases, and in both of these cases, the microcode resides in the ROM. This should be a safe change across the board. The function which loaded compiled-in microcode is also removed here in order to prevent it from being used in the future. The dummy terminators from microcode need to be removed if this change is to work when generating microcode from several microcode_blob.c files, as is the case for older socketed CPUs. Removal of dummy terminators is done in a subsequent patch.

2014-01-15Re-declare CACHE_ROM_SIZE as aligned ROM_SIZE for MTRRKyösti Mälkki
This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be set with values that are not power of 2. The region programmed as WB cacheable will include all of ROM_SIZE. Side-effects to consider: Memory region below flash may be tagged WRPROT cacheable. As an example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB. Since this can overlap CAR, we add an explicit test and fail on compile should this happen. To work around this problem, one needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and define a smaller region for WB cache. With this change flash regions outside CBFS are also tagged WRPROT cacheable. This covers IFD and ME and sections ChromeOS may use.
