2014-08-13arm: libpayload: Add cache coherent DMA memory definition and managementJulius Werner
This patch adds a mechanism to set aside a region of cache-coherent (i.e. usually uncached) virtual memory, which can be used to communicate with DMA devices without automatic cache snooping (common on ARM) without the need of explicit flush/invalidation instructions in the driver code. This works by setting aside said region in the (board-specific) page table setup, as exemplary done in this patch for the Snow and Pit boards. It uses a new mechanism for adding board-specific Coreboot table entries to describe this region in an entry with the LB_DMA tag. Libpayload's memory allocator is enhanced to be able to operate on distinct types/regions of memory. It provides dma_malloc() and dma_memalign() functions for use in drivers, which by default just operate on the same heap as their traditional counterparts. However, if the Coreboot table parsing code finds a CB_DMA section, further requests through the dma_xxx() functions will return memory from the region described therein instead.

2014-08-10coreboot_tables: reduce redundant data structuresJulius Werner
There are three coreboot table tags that all define some kind of memory region, and each has their own homologous struct. I'm about to add a fourth so I'll just clean this up and turn it into a generic struct lb_range instead.

2014-07-19device/pci_early.c: Mixes up variants of a typedefs to 'u32'Edward O'Callaghan
Unfortunately coreboot has to deal with ROMCC's short comings which has lead to a little bit of confusion due to typedefs. Essentially, coreboot defines four typedefs: * 'typedef struct device * device_t' in ramstage not in SIMPLE_DEVICE mode * 'typedef u32 device_t' in romstage or when SIMPLE_DEVICE is defined * 'typedef u32 pnp_devfn_t' * 'typedef u32 pci_devfn_t' Some early functions make use of 'device_t' over 'pci_devfn_t' and since the C type-checker does not enforce typedefs to the same type 'u32' these are never noticed. Fix these so that 'device_t' does not conflict in romstage for later work. We later plan to have 'pnp_devfn_t' and 'pci_devfn_t' as the only variants of 'u32' and 'device_t' to be a struct pointer type exclusively.

2014-05-29PCI IRQs: Swizzle PCI IRQs for PCI bridgesMike Loptien
The PCI Specification states that devices that implement a bridge and a secondary bus must swizzle (rotate) the interrupt pins according to the table below: Child Dev # Child PIN Parent PIN 0,4,8,12... A/B/C/D A/B/C/D 1,5,9,13... A/B/C/D B/C/D/A 2,6,10,14.. A/B/C/D C/D/A/B 3,7,11,15.. A/B/C/D D/A/B/C Which is also described by this equation: PIN_parent = (Pin_child + Dev_child) % 4 When a device is found and its bus number is greater than 0, it is on a bridge and needs to be swizzled. Following the string of parents up to the root bus and swizzling as we go gives us the desired swizzling result. When BIOS_SPEW is defined, it will print out each step of the swizzling process.

2014-05-10reg_script: add reg_script_run_on_dev()Aaron Durbin
The reg_script library has proven to be useful. It's also shown that many scripts operate on devices. However, certain code paths run the same script on multiple, but different, devices. In order to make that easier introduce reg_script_run_on_dev() which takes a device as a parameter. That way, chained reg_scripts are not scrictly needed to run the same script on multiple devices.

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.
