2014-12-30Provide a common CBFS wrapper for SPI storageVadim Bendebury
Coreboot has all necessary infrastructure to use the proper SPI flash interface in bootblock for CBFS. This patch creates a common CBFS wrapper which can be enabled on different platforms as required. COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the common CBFS interface and prevents default inclusion of all SPI chip drivers, only explicitly configured ones will be included when the new feature is enabled. Since the wrapper uses the same driver at all stages, enabling the new feature will also make it necessary to include the SPI chip drivers in bootblock and romstage images. init_default_cbfs_media() can now be common for different platforms, and as such is defined in the library. BUG=none TEST=manual . with this change and the rest of the patches coreboot on AP148 comes up all the way to attempting to boot the payload (reading earlier stages from the SPI flash along the way).

Always build CBMEM for romstage, even for boards that will not use it. We further restrict car_migrate_variables() runs to non-ROMCC boards without BROKEN_CAR_MIGRATE.

2014-08-11coreboot classes: Add dynamic classes to corebootFurquan Shaikh
Provide functionality to create dynamic classes based on program name and architecture for which the program needs to be compiled/linked. define_class takes program_name and arch as its arguments and adds the program_name to classes-y to create dynamic class. Also, compiler toolset is created for the specified arch. All the files for this program can then be added to program_name-y += .. Ensure that define_class is called before any files are added to the class. Check subdirs-y for order of directory inclusion. One such example of dynamic class is rmodules. Multiple rmodules can be used which need to be compiled for different architectures. With dynamic classes, this is possible.

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.

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.

An additional complication is the presence of having a relocatable ramstage which creates another path with duplication.

It might be the case that a file is being loaded from a portion of CBFS which has already been loaded into a limitted bit of memory somewhere, and we want to load that file in place, effectively, so that it's original location in CBFS overlaps with its new location.

2013-05-14coreboot: add thread cooperative multitaskingAaron Durbin
The cooperative multitasking support allows the boot state machine to be ran cooperatively with other threads of work. The main thread still continues to run the boot state machine (src/lib/hardwaremain.c). All callbacks from the state machine are still ran synchronously from within the main thread's context. Without any other code added the only change to the boot sequence when cooperative multitasking is enabled is the queueing of an idlle thread. The idle thread is responsible for ensuring progress is made by calling timer callbacks. The main thread can yield to any other threads in the system. That means that anyone that spins up a thread must ensure no shared resources are used from 2 or more execution contexts. The support is originally intentioned to allow for long work itesm with busy loops to occur in parallel during a boot. Note that the intention on when to yield a thread will be on calls to udelay().

2013-03-21cbmem: dynamic cbmem supportAaron Durbin
This patch adds a parallel implementation of cbmem that supports dynamic sizing. The original implementation relied on reserving a fixed-size block of memory for adding cbmem entries. In order to allow for more flexibility for adding cbmem allocations the dynamic cbmem infrastructure was developed as an alternative to the fixed block approach. Also, the amount of memory to reserve for cbmem allocations does not need to be known prior to the first allocation. The dynamic cbmem code implements the same API as the existing cbmem code except for cbmem_init() and cbmem_reinit(). The add and find routines behave the same way. The dynamic cbmem infrastructure uses a top down allocator that starts allocating from a board/chipset defined function cbmem_top(). A root pointer lives just below cbmem_top(). In turn that pointer points to the root block which contains the entries for all the large alloctations. The corresponding block for each large allocation falls just below the previous entry. It should be noted that this implementation rounds all allocations up to a 4096 byte granularity. Though a packing allocator could be written for small allocations it was deemed OK to just fragment the memory as there shouldn't be that many small allocations. The result is less code with a tradeoff of some wasted memory. +----------------------+ <- cbmem_top() | +----| root pointer | | | +----------------------+ | | | |--------+ | +--->| root block |-----+ | | +----------------------+ | | | | | | | | | | | | | | alloc N |<----+ | | +----------------------+ | | | | | | | | | \|/ | alloc N + 1 |<-------+ v +----------------------+ In addition to preserving the previous cbmem API, the dynamic cbmem API allows for removing blocks from cbmem. This allows for the boot process to allocate memory that can be discarded after it's been used for performing more complex boot tasks in romstage. In order to plumb this support in there were some issues to work around regarding writing of coreboot tables. There were a few assumptions to how cbmem was layed out which dictated some ifdef guarding and other runtime checks so as not to incorrectly tag the e820 and coreboot memory tables. The example shown below is using dynamic cbmem infrastructure. The reserved memory for cbmem is less than 512KiB. coreboot memory table: 0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES 1. 0000000000001000-000000000002ffff: RAM 2. 0000000000030000-000000000003ffff: RESERVED 3. 0000000000040000-000000000009ffff: RAM 4. 00000000000a0000-00000000000fffff: RESERVED 5. 0000000000100000-0000000000efffff: RAM 6. 0000000000f00000-0000000000ffffff: RESERVED 7. 0000000001000000-000000007bf80fff: RAM 8. 000000007bf81000-000000007bffffff: CONFIGURATION TABLES 9. 000000007c000000-000000007e9fffff: RESERVED 10. 00000000f0000000-00000000f3ffffff: RESERVED 11. 00000000fed10000-00000000fed19fff: RESERVED 12. 00000000fed84000-00000000fed84fff: RESERVED 13. 0000000100000000-00000001005fffff: RAM Wrote coreboot table at: 7bf81000, 0x39c bytes, checksum f5bf coreboot table: 948 bytes.

This patch adds an option to build the ramstage as a reloctable binary. It uses the rmodule library for the relocation. The main changes consist of the following: 1. The ramstage is loaded just under the cmbem space. 2. Payloads cannot be loaded over where ramstage is loaded. If a payload is attempted to load where the relocatable ramstage resides the load is aborted. 3. The memory occupied by the ramstage is reserved from the OS's usage using the romstage_handoff structure stored in cbmem. This region is communicated to ramstage by an CBMEM_ID_ROMSTAGE_INFO entry in cbmem. 4. There is no need to reserve cbmem space for the OS controlled memory for the resume path because the ramsage region has been reserved in #3. 5. Since no memory needs to be preserved in the wake path, the loading and begin of execution of a elf payload is straight forward.

2013-03-18lib: add rmodule supportAaron Durbin
A rmodule is short for relocation module. Relocaiton modules are standalone programs. These programs are linked at address 0 as a shared object with a special linker script that maintains the relocation entries for the object. These modules can then be embedded as a raw binary (objcopy -O binary) to be loaded at any location desired. Initially, the only arch support is for x86. All comments below apply to x86 specific properties. The intial user of this support would be for SMM handlers since those handlers sometimes need to be located at a dynamic address (e.g. TSEG region). The relocation entries are currently Elf32_Rel. They are 8 bytes large, and the entries are not necessarily in sorted order. An future optimization would be to have a tool convert the unsorted relocations into just sorted offsets. This would reduce the size of the blob produced after being processed. Essentialy, 8 bytes per relocation meta entry would reduce to 4 bytes.

2012-03-28Add timestamp collecting to coreboot.Vadim Bendebury
This patch adds code to initialize the time stamp collection facility in coreboot. It adds a table in the CBMEM section, which provides the base timer reading value (all other readings are offsets of this one) and an array of timestamp id/timestamp value pairs. Just two values are being added now, this will have to be used more extensively and also integrated into payloads to provide more comprehensive boot process time measurements. Also, since the CBMEM area could already contain a section (from the previous run, before reset), when processing a section addition request we should check if a section already exists and return its address, if so.
