2020-04-10Replace DEVICE_NOOP with noop_(set|read)_resourcesNico Huber
`.read_resources` and `.set_resources` are the only two device operations that are considered mandatory. Other function pointers can be left NULL. Having dedicated no-op implementations for the two mandatory fields should stop the leaking of no-op pointers to other fields.

2020-03-31security/vboot: Decouple measured boot from verified bootBill XIE
Currently, those who want to use measured boot implemented within vboot should enable verified boot first, along with sections such as GBB and RW slots defined with manually written fmd files, even if they do not actually want to verify anything. As discussed in CB:34977, measured boot should be decoupled from verified boot and make them two fully independent options. Crypto routines necessary for measurement could be reused, and TPM and CRTM init should be done somewhere other than vboot_logic_executed() if verified boot is not enabled. In this revision, only TCPA log is initialized during bootblock. Before TPM gets set up, digests are not measured into tpm immediately, but cached in TCPA log, and measured into determined PCRs right after TPM is up. This change allows those who do not want to use the verified boot scheme implemented by vboot as well as its requirement of a more complex partition scheme designed for chromeos to make use of the measured boot functionality implemented within vboot library to measure the boot process. TODO: Measure MRC Cache somewhere, as MRC Cache has never resided in CBFS any more, so it cannot be covered by tspi_measure_cbfs_hook().

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"?

2019-11-03arch/arm64: Pass cbmem_top to ramstage via calling argumentArthur Heymans
This solution is very generic and can in principle be implemented on all arch/soc. Currently the old infrastructure to pass on information from romstage to ramstage is left in place and will be removed in a follow-up commit. Nvidia Tegra will be handled in a separate patch because it has a custom ramstage entry. Instead trying to figure out which files can be removed from stages and which cbmem_top implementations need with preprocessor, rename all cbmem_top implementation to cbmem_top_romstage. Mechanisms set in place to pass on information from rom- to ram-stage will be replaced in a followup commit.

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: 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.

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.

2018-11-21(console,drivers/uart)/Kconfig: Fix dependenciesNico Huber
The dependencies of CONSOLE_SERIAL and DRIVERS_UART were somehow backwards. Fix that. Now, CONSOLE_SERIAL depends on DRIVERS_UART, because it's using its interface. The individual UART drivers select DRIVERS_UART, because they implement the interface and depend on the common UART code. Some guards had to be fixed (using CONSOLE_SERIAL now instead of DRIVERS_UART). Some other guards that were only about compilation of units were removed. We want to build test as much as possible, right?
