2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2019-09-14arm64: Uprev Arm TF and adjust to BL31 parameter changesJulius Werner
This patch uprevs the Arm Trusted Firmware submodule to the new upstream master (commit 42cdeb930). Arm Trusted Firmware unified a bunch of stuff related to BL31 handoff parameters across platforms which involved changing a few names around. This patch syncs coreboot back up with that. They also made header changes that now allow us to directly include all the headers we need (in a safer and cleaner way than before), so we can get rid of some structure definitions that were duplicated. Since the version of entry point info parameters we have been using has been deprecated in Trusted Firmware, this patch switches to the new version 2 parameter format. NOTE: This may or may not stop Cavium from booting with the current pinned Trusted Firmware blob. Cavium maintainers are still evaluating whether to fix that later or drop the platform entirely. Tested on GOOGLE_KEVIN (rk3399).

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: Have absolute paths start with '/'Julius Werner
Currently DT paths are *not* expected to start with '/'. This is not what the spec says (see Devicetree Specification v0.2, 2.2.3 Path Names) and also not what is done by Linux. Change dt_find_node_by_path() to expect paths to start with '/' and add a leading '/' to all DT path strings. Besides the compatibility with the spec this change is also needed to support aliases in the future.

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.
