2019-06-24add ctype.h headerJoel Kitching
Sometimes coreboot needs to compile external code (e.g. vboot_reference) using its own set of system header files. When these headers don't line up with C Standard Library, it causes problems. Create ctype.h header file. Relocate ctype.h functions from string.h into ctype.h. Update source files which call ctype.h functions accordingly.

2019-06-21fit: Check all compat strings for highest matchJulius Werner
The compat string matching code was mostly copied from depthcharge. One of the few differences is that we now store the list of compat strings we're willing to match in a list rather than an array. Since our lists insert at the front, that means the strings are now ordered lowest to highest (not highest to lowest like in depthcharge). We did rewrite the compat_rank matching code to accomodate for that... however, what we didn't do is remove the break-statement in the loop that matches all compat strings. When we search the lowest priority first, we can't abort the search as soon as we found a match -- we have to keep looking because we might find a higher priority match later. This patch fixes the issue so that my Kevin can actually match for google,kevin-rev5 (and doesn't just jump at the first best google,kevin match).

This patch adds support to boot FIT image configurations consisting of a base device tree and one or more overlays.

2019-06-21fit: Add device tree compressionJulius Werner
This patch adds support for compressing individual device trees in the FIT image. In order to make this efficient, we'll have to pull the compatible property out of the FDT and store it directly in the config node of the FIT image, so that we don't have to scan (and therefore decompress) every single FDT on boot. Device tree compression is only supported for FIT images that have this external compatible property. For older images with no compression, we still support fallback to scanning the FDT for the property.

2019-06-21fit: Refactor config node handlingJulius Werner
This patch makes some minor refactoring to the way the FIT parser handles config nodes. A lot of this code was written in the dawn age of depthcharge when its device tree library wasn't as well-stocked yet, so some of it can be rewritten nicer with more high-level primitives. There's no point in storing both the string name and the actual FDT node of a FIT image node separately, since the latter also contains the former, so remove that. Also eliminate code for the case of not having an FDT (which makes no sense), and move some more FDT validity/compat checking into fit_update_compat() (mostly in anticipation of later changes). This patch was adapted from depthcharge's http://crosreview.com/1553456 with a couple of modifications specific to coreboot's custom FIT loading code.

On the other hand it's occasionally desirable to put a string constant in there without having to strdup() it all the time... let's just live with the tiny implicit assumption that the data we'd want to modify (phandle references, mostly) will never be added from string constants, and put a cast in dt_add_string_prop().

2019-06-04device_tree: Drop sub-node path lookup from dt_find_node_by_path()Julius Werner
Besides looking up a node with an absolute path dt_find_node_by_path() currently also supports finding a sub-node of a non-root node. All callers of the function pass the root node though, so it seems there is no real need for this functionality. Also it is planned to support DT path names with aliases, which would become messy in combination with the lookup from a sub-node. Change the interface of dt_find_node_by_path() to receive the DT tree object instead of a parent node and adapt all callers accordingly.

2019-06-04device_tree: Add phandle caching and lookupsJulius Werner
This patch caches phandles when unflattening the device tree, so we don't have to look up the phandle property again every time we're trying to find the phandle of a node. This is especially important when supporting phandle lookups, which are also added. In addition we keep track of the highest phandle in the whole tree, which will be important for applying overlays later. With this, dt_get_phandle(node) becomes obsolete because the phandle is already available as a member variable in the node.

This patch moves them to string.c to be more consistent with our usual coding practices. Leaving the ctype functions as static inline because they actually seem small and collapsible enough that inlining seems reasonable. Also clarified the situation of strdup() and strconcat() a bit more, optimized strrchr() to be single-pass, fixed a bug with using strchr() to find '\0' and got rid of unnecessary register keywords.

With CB:32726 ("lib/timestamp: Make timestamp_sync_cache_to_cbmem() in postcar") timestamps are synced from cache to cbmem in postcar as well. For postcar, the cache lives in BSS just like ramstage. This change updates TIMESTAMP_CACHE_IN_BSS to include both ramstage and postcar and uses this instead of ENV_RAMSTAGE to check for cache location. Ideally, it would be good to get rid of timestamp cache in postcar and ramstage completely since early cbmem init is enabled by default in coreboot and it is guaranteed that cbmem is recovered before timestamps are added in ramstage or postcar. This change is being pushed in as a temporary fix while I make the changes to remove timestamp cache from romstage and postcar completely.

2019-04-02vboot: Change oprom checks to CONFIG_VBOOT, assert OPROM_MATTERSJulius Werner
Skipping display init on normal-mode boot is a vboot feature, not specific to Chrome OS. Fix the code in display_init_required() and pci_dev_init() to check CONFIG_VBOOT rather than CONFIG_CHROMEOS now that the two aren't always the same anymore. Also add a check to guarantee at compile time that CONFIG_VBOOT_OPROM_MATTERS is enabled on all platforms that make a check to this function (when CONFIG_VBOOT is also enabled). The whole display skipping mechanism is based on the oprom_needed NVRAM flag, and skipping display init without enabling the option to tell vboot that it needs to pay attention to that flag would make the whole thing not work right.

2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2018-10-25selfboot: create selfboot_check function, remove check paramRonald G. Minnich
The selfboot function was changed at some point to take a parameter which meant "check the allocated descriptors to see if they target regions of real memory." The region check had to be buried deep in the last step of loading since that is where those descriptors were created and used. An issue with the use of the parameter was that it was not possible for compilers to easily divine whether the check code was used, and it was hence possible for the code, and its dependencies, to be compiled in even if never used (which caused problems for the rampayload code). Now that bounce buffers are gone, we can hoist the check code to the outermost level. Further, by creating a selfload_check and selfload function, we can make it easy for compilers to discard unused code: if selfload_check is never called, all the code it uses can be discarded too.

2018-10-22intel: Use CF9 reset (part 2)Patrick Rudolph
Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also implement board_reset() as a "full reset" (aka. cold reset) as that is what was used here for hard_reset(). Drop soc_reset_prepare() thereby, as it was only used for APL. Also, move the global-reset logic. We leave some comments to remind us that a system_reset() should be enough, where a full_reset() is called now (to retain current behaviour) and looks suspicious. Note, as no global_reset() is implemented for Denverton-NS, we halt there now instead of issuing a non-global reset. This seems safer; a non-global reset might result in a reset loop.

2018-10-22reset: Provide new single-function reset APINico Huber
board_reset() replaces the existing common reset API. There is no common distinction between reset types across platforms, hence, common code could never decide which one to call. Currently only hard_reset() is used by common code. We replace these calls and provide a fall-back to the current hard_reset() implemen- tation. The fall-back will be removed along with hard_reset() after the transition of all boards.

2018-10-11selfboot: remove bounce buffersRonald G. Minnich
Bounce buffers used to be used in those cases where the payload might overlap coreboot. Bounce buffers are a problem for rampayloads as they need malloc. They are also an artifact of our x86 past before we had relocatable ramstage; only x86, out of the 5 architectures we support, needs them; currently they only seem to matter on the following chipsets: src/northbridge/amd/amdfam10/Kconfig src/northbridge/amd/lx/Kconfig src/northbridge/via/vx900/Kconfig src/soc/intel/fsp_baytrail/Kconfig src/soc/intel/fsp_broadwell_de/Kconfig The first three are obsolete or at least could be changed to avoid the need to have bounce buffers. The last two should change to no longer need them. In any event they can be fixed or pegged to a release which supports them. For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the value needed in 1999 for the 32-bit Linux kernel, the original ramstage) to 0xe00000 (14 Mib) which will put the non-relocatable x86 ramstage out of the way of any reasonable payload until we can get rid of it for good. 14 MiB was chosen after some discussion, but it does fit well: o Fits in the 16 MiB cacheable range coreboot sets up by default o Most small payloads are well under 14 MiB (even kernels!) o Most large payloads get loaded at 16 MiB (especially kernels!) With this change in place coreboot correctly still loads a bzImage payload. Werner reports that the 0xe00000 setting works on his broadwell systems.
