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.

2013-12-21exynos5250: Implement support to boot with USB A-A firmware uploadJulius Werner
This patch implements the basic infrastructure required to use the USB A-A firmware upload feature on Exynos5 processors with Coreboot. It will require a corresponding host-side script that activates the feature and uploads the correct image parts in the correct order to harcoded target addresses, as described in the comments of alternate_cbfs.c. Also fixes a bug in the Google Snow mainboard where it would not correctly initialize the pinmux configuration for the SPI flash bus. During a normal SPI boot the IROM would already do that for you, but when booting from USB you have to do it yourself.

2013-07-25Redefine pci_bus_default_ops as functionKyösti Mälkki
Taking device_t as a parameter, this allows to alter the PCI config access handlers. This is useful to add tracing of PCI config writes for devices having problems to initialise correctly. On older AMD platform PCI MMIO may not be able to fully configure all PCI devices/nodes, while MMIO_SUPPORT_DEFAULT would be preferred due to its atomic nature. So those can be forced to IO config instead.

2013-07-15ARM: Define custom ELF headers for ARM.Gabe Black
At least when building with the gnu toolchain, the headers the linker automatically generate save space for the actual ELF headers in one of the loadable segments. This creates two problems. First, the data you intended to be at the start of the image doesn't actually show up there, it's actually the ELF headers. Second, the ELF headers are essentially useless for firmware since there's currently nothing to tell you where they are, and even if there was, there isn't much of a reason to look at them. They're useful in userspace for, for instance, the dynamic linker, but not really in firmware. This change adds a PHDRS construct to each of the linker scripts used on ARM which define a single segment called to_load which does not have the flag set which would tell the linker to put headers in it. The first section defined in the script has ": to_load" to tell the linker which segment to put it in, and from that point on the other sections go in there by default.

The options that keep track of whether there are arch versions of the standard string functions shouldn't be in the arch/x86 directory since they apply to all architectures. Move them into the higher level, shared Kconfig defaulting to off. Then, in each applicable arch (currently all of them) they can be selected to on.

2013-07-10ARM: Don't leave alignment checking on after the exception test.Gabe Black
Currently, the exception handling code on ARM turns on alignment checks as an easy way to generate an exception for testing purposes. It was leaving it on which disabled unaligned accesses for other, unlreated code running later. This change adjusts the code so the original value of the alignment bit is restored after the test exception.

2013-07-10ARM: Tell the linker memset and memcpy are functions.Gabe Black
The memset and memcpy functions are assembled as ARM code, likely because that's the default of the assembler. Without special annotation, the assembler and linker don't know that those symbols are functions which need special handling so that ARM/thumb issues are handled properly. This change adds that annotation which gets those functions working in Coreboot which is compiled as thumb. Libpayload and depthcharge are compiled as ARM so they don't *need* the annotation since it just works out in ARM mode, but it's the safe thing to do in case we change that in the future. We should explicitly select ARM vs. thumb when assembling assembly files to be consistent across builds and toolchains.
