mtk_init_mcu uses DRAM_DMA section as CBFS buffer. The change "mediatek/mt8183: Remove DRAM_DMA section" is reverted for using mtk_init_mcu. On mt8173 and mt8192, this region is used by DMA hardware and is marked as non-cacheable resource. On mt8183, this region is reserved as CBFS buffer, so it is not necessary to be marked as non-cacheable resource.

This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows SoC/mainboard to provide a linker file for the platform. x86 already provides a default memlayout.ld under src/arch/x86. With this new Kconfig variable, it is possible for the SoC/mainboard code for x86 to provide a custom linker file as well. Makefile.inc is updated for all architectures to use this new Kconfig variable instead of assuming memlayout.ld files under a certain path.

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().

2019-11-14lib/fmap: Add optional pre-RAM cacheJulius Werner
This patch adds an optional pre-RAM cache for the FMAP which most platforms should be able to use, complementing the recently added post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP about half a dozen times from flash in verstage, which will all be coalesced into a single read with this patch. It will also help future vboot improvements since when FMAP reads become "free" vboot doesn't need to keep track of so much information separately. In order to make sure we have a single, well-defined point where the new cache is first initialized, eliminate the build-time hardcoding of the CBFS section offsets, so that all CBFS accesses explicitly read the FMAP. Add FMAP_CACHEs to all platforms that can afford it (other than the RISC-V things where I have no idea how they work), trying to take the space from things that look like they were oversized anyway (pre-RAM consoles and CBFS caches).

Currently full calibration with DVFS (which implies tripling memory training time for multiple frequencies) will be run in recovery mode, which takes up to 30 seconds with serial console enabled. However, in recovery mode the system should be running only the recovery programs with minimal services. DVFS should be not needed. In order to improve stability and system boot time, we want to disable DVFS training in recovery mode.
