2019-11-26soc/mediatek/mt8183: disable BBLPM of DCXO coreWeiyi Lu
When we only enable XO_SOC and mask most BBLPM requests, the BBLPM HW arbiter will have DCXO core to enter Baseband Low-Power Mode(BBLPM). Under BBLPM mode, inaccurate(about 1.5KHz offset) 26MHz clocks from crystal is provided and crystal voltage will drop from 1.8V to 0.7V or lower. In order to ensure the stability by always outputting an accuarate system clock when system is running. We should disable BBLPM when only XO_SOC enabled.

2019-11-18include: Make stdbool.h a separate fileJulius Werner
This patch moves the traditional POSIX stdbool.h definitions out from stdint.h into their own file. This helps for using these definitions in commonlib code which may be compiled in different environments. For coreboot everything should chain-include this stuff via types.h anyway so nothing should change.

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).

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.
