Though coreboot started as x86 only, the current approach to x86 linking is out of the norm with respect to other architectures. To start alleviating that the way ramstage is linked is partially unified. A new file, program.ld, was added to provide a common way to link stages by deferring to per-stage architectural overrides. The previous ramstage.ld is no longer required. Note that this change doesn't handle RELOCATABLE_RAMSTAGE because that is handled by rmodule.ld.

2015-09-09x86: don't create MAINBOARDDIR/romstage.inc for !ROMCC boardsAaron Durbin
Previously, the x86 romstage build process was unconditionally creating a romstage.inc and adding it to crt0s. This step is inherently not necessary in the !ROMCC case becaue the romstage.inc was created by the compiler outputting assembler. That means MAINBOARDDIR/romstage.c is truly a C environment that requires some sort of assembler stub to call into (cache_as_ram.inc from the chipset dirs). Therefore, remove this processing. The result is that MAINBOARDDIR/romstage.c can use the normal build steps in creating an object and linking. The layout of romstage.elf will change but that's only from a symbol perspective.

2015-08-13x86: parameterize asl_template for CBFS inclusionAaron Durbin
The asl_template previously unconditionally included dsdt.aml. However, COMPILE_IN_DSDT=y results in the dsdt.aml being linked directly into ramstage. Thus the information is duplicated. The inclusion of this file unconditionally throws some errors as certain assets need to be included in CBFS. However, as there isn't fine-grained ordering control in how files are added fixed resource requirements for other assets collide result in failure to build. To remedy both things, provide a 2nd argument to asl_template which defaults to 'y' for CBFS addition. In the COMPILE_IN_DSDT=y case pass 'n' so that dsdt.aml is no longer added. BUG=chrome-os-partner:43419 BRANCH=None TEST=For glados: Built with COMPILE_IN_DSDT=y. dsdt.aml not included. Built with COMPILE_IN_DSDT=n. dsdt.aml was included.

2015-08-13amd: raminit sysinfo offset fixAaron Durbin
The sysinfo object within the k8 ram init is used to communicate progess/status from all the nodes in the system. However, the code was assuming where the sysinfo object lived in cache-as-ram. The layout of cache-as-ram is dynamic so one needs to do the lookup of the correct address at runtime. The way the amd code is compiled by #include'ing .c files makes the solution a little more complex in that some cache-as-ram support code needed to be refactored.

2015-07-29arm, arm64, mips: Add rough static stack size checks with -Wstack-usageJulius Werner
We've seen an increasing need to reduce stack sizes more and more for space reasons, and it's always guesswork because no one has a good idea how little is too litte. We now have boards with 3K and 2K stacks, and old pieces of common code often allocate large temporary buffers that would lead to very dangerous and hard to detect bugs when someone eventually tries to use them on one of those. This patch tries improve this situation at least a bit by declaring 2K as the minimum stack size all of coreboot code should work with. It checks all function frames with -Wstack-usage=1536 to make sure we don't allocate more than 1.5K in a single buffer. This is of course not a perfect test, but it should catch the most common situation of declaring a single, large buffer in some close-to-leaf function (with the assumption that 0.5K is hopefully enough for all the "normal" functions above that). Change one example where we were a bit overzealous and put a 1K buffer into BSS back to stack allocation, since it actually conforms to this new assumption and frees up another kilobyte of that highly sought-after verstage space. Not touching x86 with any of this since it's lack of __PRE_RAM__ BSS often requires it to allocate way more on the stack than would usually be considered sane. BRANCH=veyron BUG=None TEST=Compiled Cosmos, Daisy, Falco, Blaze, Pit, Storm, Urara and Pinky, made sure they still build as well as before and don't show any stack usage warnings.

2015-06-09cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() APIKyösti Mälkki
Squashed and adjusted two changes from chromium.git. Covers CBMEM init for ROMTAGE and RAMSTAGE. cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API There are several use cases for performing a certain task when CBMEM is first set up (usually to migrate some data into it that was previously kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them differently: timestamp migration is called explicitly from cbmem_initialize(), certain x86-chipset-specific tasks use the CAR_MIGRATION() macro to register a hook, and the CBMEM console is migrated through a direct call from romstage (on non-x86 and SandyBridge boards). This patch decouples the CAR_MIGRATION() hook mechanism from cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer description of what it really does. All of the above use cases are ported to this new, consistent model, allowing us to have one less line of boilerplate in non-CAR romstages. BRANCH=None BUG=None TEST=Built and booted on Nyan_Blaze and Falco with and without CONFIG_CBMEM_CONSOLE. Confirmed that 'cbmem -c' shows the full log after boot (and the resume log after S3 resume on Falco). Compiled for Parrot, Stout and Lumpy.

Oops. This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism to the cbmem_initialize() call in ramstage. The macro is split into explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as possible and prevent surprises (although just using a single macro and relying on the Makefiles to link an object into all appropriate stages would also work). This allows us to get rid of the explicit cbmemc_reinit() in ramstage (which I somehow accounted for in the last patch without realizing that timestamps work exactly the same way...), and replace the older and less flexible cbmem_arch_init() mechanism. Also added a size assertion for the pre-RAM CBMEM console to memlayout that could prevent a very unlikely buffer overflow I just noticed. BRANCH=None BUG=None TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once again show up. Compile-tested for Rambi and Samus.

2015-06-05lib: Unify log2() and related functionsJulius Werner
This patch adds a few bit counting functions that are commonly needed for certain register calculations. We previously had a log2() implementation already, but it was awkwardly split between some C code that's only available in ramstage and an optimized x86-specific implementation in pre-RAM that prevented other archs from pulling it into earlier stages. Using __builtin_clz() as the baseline allows GCC to inline optimized assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and to perform constant-folding if possible. What was previously named log2f on pre-RAM x86 is now ffs, since that's the standard name for that operation and I honestly don't have the slightest idea how it could've ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm with Float result, whereas the Find First Set operation has no direct correlation to logarithms that I know of). Make ffs result 0-based instead of the POSIX standard's 1-based since that is consistent with clz, log2 and the former log2f, and generally closer to what you want for most applications (a value that can directly be used as a shift to reach the found bit). Call it __ffs() instead of ffs() to avoid problems when importing code, since that's what Linux uses for the 0-based operation. CQ-DEPEND=CL:273023 BRANCH=None BUG=None TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new log2() and __ffs() results on Falco for a bunch of test values.

2015-06-02cbfs: new API and better program loadingAaron Durbin
A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.

2015-06-02arm64: Decouple MMU functions from memrangesJulius Werner
The current arm64 MMU interface is difficult to use in pre-RAM environments. It is based on the memranges API which makes use of malloc(), and early stages usually don't have a heap. It is also built as a one-shot interface that requires all memory ranges to be laid out beforehand, which is a problem when existing areas need to change (e.g. after initializing DRAM). The long-term goal of this patch is to completely switch to a configure-as-you-go interface based on the mmu_config_range() function, similar to what ARM32 does. As a first step this feature is added side-by-side to the existing interface so that existing SoC implementations continue to work and can be slowly ported over one by one. Like the ARM32 version it does not garbage collect page tables that become unused, so repeated mapping at different granularities will exhaust the available table space (this is presumed to be a reasonable limitation for a firmware environment and keeps the code much simpler). Also do some cleanup, align comments between coreboot and libpayload for easier diffing, and change all error cases to assert()s. Right now the code just propagates error codes up the stack until it eventually reaches a function that doesn't check them anymore. MMU configuration errors (essentially just misaligned requests and running out of table space) should always be compile-time programming errors, so failing hard and fast seems like the best way to deal with them. BRANCH=None BUG=None TEST=Compile-tested rush_ryu. Booted on Oak and hacked MMU init to use mmu_config_range() insted of memranges. Confirmed that CRCs over all page tables before and after the change are equal.

Use separate CBMEM allocations for stack and heap on S3 resume path. The allocation of HIGH_SCRATCH_MEMORY is specific to AGESA and is moved out of globals and ACPI. This region is a replacement for BIOS_HEAP_SIZE used on non-resume paths.
