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).

Due to a schematic error, our code was written to configure more I2S0 pins than are actually used. We're also pinmuxing the whole bank of pins over to the I2S controller even though we don't need them all. Restrict the GPIO initialization and pinmuxing to the pins we really need so the other ones can be correctly used as SKU ID pins on Scarlet. Also, move the "audio" IO voltage domain selection to the other such selections in the bootblock, since that covers two whole banks of GPIOs and there's no guarantee that they're all used for audio (and thus not needed before ramstage).

On older Grus, GPIO0_A2 was an audio voltage rail enable line. On Scarlet, we instead moved the audio codec enable (previously on GPIO1_A2) there. Unfortunately the code still had some hardcoded leftovers that were overlooked in the initial port and make our speakers smell weird. This patch fixes the incorrect GPIO settings and adds the speaker enable pin to the GPIOs passed through the coreboot table, so that depthcharge doesn't have to keep its own definition of the pin which may go out of sync.

2017-01-13gru: Tuning USB 2.0 PHY0 and PHY1 host-portWilliam wu
The commit 0ba3b2593b0c ("gru: Tuning USB 2.0 PHY to increase compatibility") bypass ODT to set the max driver strength for the Type-C otg-port, it works well on otg-port when connected with USB2.0 devices. Unfortunately, because the Type-C otg-port and host-port are consisted in one USB2 PHY, so bypass ODT will have an effect on both host-port and otg-port. I have tested the host-port eye-diagram, the result shows that if we bypass ODT, the host- port eye-diagram height will become to high, more than 500mv, this may cause USB 2.0 high-speed enumeration failure. This patch bypass ODT for host-port separately, and then we can reduce the host-port driver strength without affecting the otg-port driver strength.

2016-12-06google/gru: Power-cycle USB ports in developer/recovery modesJulius Werner
Gru only uses USB 2.0 in firmware to avoid all the madness associated with Type-C port orientation and USB 3.0 tuning. We do this by isolating the SuperSpeed lines in the Type-C PHY so it looks like they aren't connected to the device. Unfortunately, some devices seem to already get "locked" into SuperSpeed mode as soon as they detect Rx terminations once, and can never snap out again on their own. Since the terminations are already connected during power-on reset we cannot disable them fast enough to prevent this, and the only solution we found to date is to power-cycle the whole USB port. Now, Gru's USB port power is controlled by the EC, and unfortunately we have no direct host command to control it. We do however have a command to force a certain USB PD "role", and forcing our host into "sink" mode makes it stop sourcing power to the port. So for lack of a saner solution we'll use this to work around our problem. BRANCH=gru BUG=chrome-os-partner:59346 TEST=Booted Kevin in recovery mode, confirmed that my "problem stick" gets detected immediately (whereas previously I had to unplug/replug it).

GPIO1_B3 (WLAN_MODULE_RST#) defaults as a pull-up input, but it is also "pulled up" by 1.8V_WLAN. However, 1.8V_WLAN remains low for some time during early boot. This leaves the signal floating somewhere in the middle. This has two potential issues: (1) we're leaking some power for some (hopefully) short period of time (2) we are possibly screwing with the Wifi power sequence; we aren't supposed to deassert PDn (i.e., MODULE_RST#) until all the rails have fully ramped for some period of time Neither of the above issues are likely to be significant, but it is nice to fix, I expect.

2016-08-11rockchip/rk3399: Add code to neuter Type-C PHY for firmware USBJulius Werner
The Rockchip RK3399 integrates a USB Type-C PHY in charge of things like SuperSpeed line muxing for rotated cable orientations in the SoC. While fancy, this is very complicated and we don't want to implement support for the whole thing in firmware. The USB Type-C standard has intentionally been designed in a way that the USB 2.0 (HighSpeed) lines always "just work" in any orientation (by just shorting different pins in the connector together) so that simple use cases like ours can get basic USB functionality without much hassle. However, a semi-configured Type-C PHY can confuse USB 3.0 capable devices into thinking we're actually supporting SuperSpeed, and fail at that rather than establishing a reliable HighSpeed connection. This patch sets enough bits in the Type-C PHY to electrically isolate the SuperSpeed lines from the connector so that the connected device isn't going to get any fancy ideas and reliably falls back to USB 2.0. Also clean up the rest of the USB code while we're at it: avoid writing a few bits that are already in the right state from their reset values anyway, or reading values whose content we already know for this SoC. Rename the USB controllers to the name actually used in the Rockchip documentation (USB OTGx) rather than the name blindly copied from Exynos code (USB DRDx). BRANCH=None BUG=chrome-os-partner:54621 TEST=Plug a USB 3.0 Patriot Memory stick into both ports in all orientations, observe how it gets reliably detected now (safe for some known hardware issues on my board).
