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.

For x86 systems employing CONFIG_LATE_CBMEM_INIT, set_top_of_ram() is called in ramstage to note the upper address of the 32-bit address space. This in turn is consumed by cbmem. However, in this scenario cbmem_top() cannot always be relied upon because get_top_of_ram() doesn't return the same value provided to set_top_of_ram(). To fix the inconsistency in ramstage save the value passed in to set_top_of_ram() and defer to it as the return value for cbmem_top().

Intermediate linking may distort linker behavior (in particular related to weak symbols). The idea is that archives are closer to 'just a list of object files', and ideally makes the linker more predictable. Using --whole-archive, the linker doesn't optimize out object files just because their symbols were already provided by weak versions. However it shouldn't be used for libgcc, because that one has some unexpected side-effects.

2015-05-19arm64: Make SPSR exception masking on EL2 transition explicitJulius Werner
The configuration of SPSR bits that mask processor exceptions is kinda oddly hidden as an implict part of the transition() function right now. It would be odd but not impossible for programs to want to be entered with enabled exceptions, so let's move these bits to be explicitly set by the caller like the rest of SPSR instead. Also clear up some macro names. The SPSR[I] bit is currently defined as SPSR_IRQ_ENABLE, which is particularly unfortunate since that bit actually *disables* (masks) interrupts. The fact that there is an additional SPSR_IRQ_MASK definition with the same value but a different purpose doesn't really help. There's rarely a point to have all three of xxx_SHIFT, xxx_MASK and xxx_VALUE macros for single-bit fields, so simplify this to a single definition per bit. (Other macros in lib_helpers.h should probably also be overhauled to conform, but I want to wait and see how many of them really stay relevant after upcoming changes first.)
