2014-05-09Intel FSP: add a shared set of functions for the FSPMartin Roth
- Move the non chipset-specific fsp pieces out of the chipset into a shared area. This is used by northbridge / southbrige / SOC code. It pulls in pieces from Kconfig, Makefile and FSP specific code. - Enabled in the CPU code with a Kconfig "select PLATFORM_USES_FSP" Change-Id: I7ffa934c1df09b71d48a876a56e3b888685870b8 Signed-off-by: Martin Roth <gaumless@gmail.com> Signed-off-by: Martin Roth <martin.roth@se-eng.com> Reviewed-on: http://review.coreboot.org/5635 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones <marc.jones@se-eng.com>
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.

2014-01-15Re-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.

2013-11-19Add GRUB2 payload to build systemVladimir Serbinenko
Since a long time GRUB 2 is a viable payload alternative to SeaBIOS and FILO. So make it easy for coreboot users to use GRUB 2 as a payload by integrating it into coreboot’s build system, so it can be selected in Kconfig. As the last GRUB 2 release 2.00 is too old and has several bugs when used as a coreboot payload only allow to build GRUB 2 master until a new GRUB release is done. The downside is, that accidental breakage in GRUB’s upstream does not affect coreboot users. Currently the GRUB 2 payload is built with the default modules which results in an uncompressed size of around 730 kB. Compressed it has a size of 340 kB, so it should be useable with 512 kB flash ROMs. Tested with QEMU.

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().

This is just the framework where it is the responsibility of the chipset/board to provide the implementation of timer_monotonic_get(). The reason structs are used instead of native types is to allow for future changes to the data structure without chaning all the call sites.

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.

2013-03-21coreboot: introduce CONFIG_RELOCATABLE_RAMSTAGEAaron Durbin
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.

In order to provide some insight on what code is executed during coreboot's run time and how well our test scenarios work, this adds code coverage support to coreboot's ram stage. This should be easily adaptable for payloads, and maybe even romstage. See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for more information. To instrument coreboot, select CONFIG_COVERAGE ("Code coverage support") in Kconfig, and recompile coreboot. coreboot will then store its code coverage information into CBMEM, if possible. Then, run "cbmem -CV" as root on the target system running the instrumented coreboot binary. This will create a whole bunch of .gcda files that contain coverage information. Tar them up, copy them to your build system machine, and untar them. Then you can use your favorite coverage utility (gcov, lcov, ...) to visualize code coverage.

2012-10-04pirq_routing: Allow routing with more than 4 PIRQ linksAlexandru Gagniuc
pirq_routing_irqs assumed that only four links are available for PIRQ routing, INTA to INTD. Some chipsets provide more, up to INTH. When pirq_routing_irqs found a link number greater than 4 in the pirq table, it would not assign that IRQ. This is a shame, as it limits the flexibility of routing IRQs. Make the maximum number of links a Kconfig variable, and modify the code to respect it. This works beatifully on the VX900, which provides 8 routable interrupts. While we're at it, also refactor pirq_routing_irqs, and add some much needed comments. Rename pirq_routing_irqs to pirq_route_irqs to demistify the role of this function. The copyrights added were determined from git log filename.

Add an option to make compression of ramstage configurable. Right now it is always compressed. On my Thinkpad, the complete boot to grub takes 4s, with around 1s required for decompressing ramstage.
