2019-11-11region: add rdev_chain_full()Aaron Durbin
Instead of open coding an offset of 0 and querying the size of a region device provide a rdev_chain_full() helper function that does that for the caller. For the existing users that match this pattern convert them to using rdev_chain_full().

With this change cbfs_boot_locate will check the RO (COREBOOT) region if a file can not be found in the active RW region. By doing so it is not required to duplicate static files that are not intended to be updated to the RW regions. The coreboot image can still be updated by adding the file to the RW region. This change is intended to support VBOOT on systems with a small flash device.

2019-11-05security/vboot: Removed vboot_prepare from vboot_locatorWim Vervoorn
When prog_locate() is called in the stage VBOOT is starting from and the image to be loaded is not the target image vboot_prepare() may be called too early. To prevent this vboot_prepare() is removed from the vboot_locator structure. This allows more control over the start of the vboot logic. To clarify the change the vboot_prepare() has been renamed to vboot_run_logic() and calls to initialize vboot have been added at the following places: postcar_loader: when VBOOT starts in ROMSTAGE romstage_loader: when VBOOT starts in BOOTBLOCK ramstage_loader: when VBOOT starts in ROMSTAGE BUG=N/A TEST=tested on facebook fbg1701 Change-Id: Id5e8fd78458c09dd3896bfd142bd49c2c3d686df Signed-off-by: Wim Vervoorn <wvervoorn@eltan.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/36543 Reviewed-by: Frans Hendriks <fhendriks@eltan.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2019-09-27fmap: Add get_fmap_flash_offset()Furquan Shaikh
CB:35377 changed the behavior of find_fmap_directory() to return pointer to CBMEM_ID_FMAP if fmap is cached in cbmem. lb_boot_media_params() calls find_fmap_directory to add offset of fmap in flash to coreboot table. However, because of the change in behavior of find_fmap_directory(), it ended up adding 0 as the offset. This change adds a new function get_fmap_flash_offset() which returns the offset of fmap in flash. Ideally, all payloads should move to using the FMAP from CBMEM. However, in order to maintain compatibility with payloads which are not updated, ensure that fmap_offset is updated correctly. Since find_fmap_directory() is no longer used outside fmap.c, this change also removes it from fmap.h and limits scope to fmap.c. In a follow up patch, we need to push a change to libpayload to expose the fmap cache pointer to lib_sysinfo.

2019-09-15lib/coreboot_table: Show splashscreen in lb_table_initJohanna Schander
Every vga init implementation needs to cache the framebuffer state to be able to fill the lb_framebuffer struct later on in the fill_lb_framebuffer call. Showing the bootsplash afterwards guarantees to have the same interface into all the vga drivers. This is by far from ideal, as it only allows for a single driver at compile-time and should be adapted in the future. It was tested on the wip razer blade stealth using vgabios @ 1280x1024 and also in Qemu @ 1280x1024. By default the qemu framebuffer will be initialized in 800x600@32. This can be overwriten by configuration by setting CONFIG_DRIVERS_EMULATION_QEMU_BOCHS_{X,Y}RES .

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 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).

2019-06-04device_tree: Make FDT property data non-constJulius Werner
FDT property data should not be const -- sometimes we need to update it, for example when fixing up phandles in an overlay. 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.

There's no clear reason why most of coreboot's basic string functions are static inline. These functions don't particularly benefit from inlining (at least not notably more than other functions). 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.

2019-05-19timestamp: Update TIMESTAMP_CACHE_IN_BSS to include ENV_POSTCARFurquan Shaikh
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.
