2020-10-22sec/intel/txt: Allow skipping ACM NOP functionAngel Pons
This is merely used to test whether the BIOS ACM calling code is working properly. There's no need to do this on production platforms. Testing on Haswell showed that running this NOP function breaks S3 resume with TXT. Add a Kconfig bool to control whether the NOP function is to be invoked.

2020-10-22sec/intel/txt: Move DPR size to KconfigAngel Pons
Instead of hardcoding the size in code, expose it as a Kconfig symbol. This allows platform code to program the size in the MCH DPR register.

2020-08-07security/intel/txt: Allow using CF9 reset, tooAngel Pons
Soften the hard dependency on SOC_INTEL_COMMON_BLOCK_SA by allowing CF9 resets to be used in place of global resets. If both types of reset are available, prefer a global reset. This preserves current behavior, and allows more platforms to use the TXT support code, such as Haswell.

2020-07-31security/intel/txt: Add Intel TXT supportPhilipp Deppenwiese
Add TXT ramstage driver: * Show startup errors * Check for TXT reset * Check for Secrets-in-memory * Add assembly for GETSEC instruction * Check platform state if GETSEC instruction is supported * Configure TXT memory regions * Lock TXT * Protect TSEG using DMA protected regions * Place SINIT ACM * Print information about ACMs Extend the `security_clear_dram_request()` function: * Clear all DRAM if secrets are in memory Add a config so that the code gets build-tested. Since BIOS and SINIT ACM binaries are not available, use the STM binary as a placeholder. Tested on OCP Wedge100s and Facebook Watson * Able to enter a Measured Launch Environment using SINIT ACM and TBOOT * Secrets in Memory bit is set on ungraceful shutdown * Memory is cleared after ungraceful shutdown Change-Id: Iaf4be7f016cc12d3971e1e1fe171e6665e44c284 Signed-off-by: Philipp Deppenwiese <zaolin@das-labor.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/37016 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Christian Walter <christian.walter@9elements.com>

2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
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.
