2024-01-24driver/parade to /driver/wwan: Rename Makefiles from .inc to .mkMartin Roth
The .inc suffix is confusing to various tools as it's not specific to Makefiles. This means that editors don't recognize the files, and don't open them with highlighting and any other specific editor functionality. This issue is also seen in the release notes generation script where Makefiles get renamed before running cloc.

2022-03-09commonlib/bsd: Remove cb_err_tJulius Werner
cb_err_t was meant to be used in place of `enum cb_err` in all situations, but the choice to use a typedef here seems to be controversial. We should not be arbitrarily using two different identifiers for the same thing across the codebase, so since there are no use cases for serializing enum cb_err at the moment (which would be the primary reason to typedef a fixed-width integer instead), remove cb_err_t again for now.

2022-02-07treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius Werner
Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result. Then doing the same thing for BIOS_WARN with 's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi' Signed-off-by: Julius Werner <jwerner@chromium.org> Change-Id: I3d0573acb23d2df53db6813cb1a5fc31b5357db8 Reviewed-on: https://review.coreboot.org/c/coreboot/+/61309 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr> Reviewed-by: Lance Zhao Reviewed-by: Jason Glenesk <jason.glenesk@gmail.com>

2021-05-08drivers/sn65dsi86: Switch EDID reading to use "indirect mode"Julius Werner
The SN65DSI86 eDP bridge supports two ways to read the EDID: for now we've been using "direct mode", which works by basically making the bridge I2C device listen to another chip address besides its own and proxy all requests received there directly to the eDP AUX channel. The great part about that mode is that it is super easy and hassle-free to use. The not so great part about it is that it doesn't work: for EDID extensions, the last byte (which happens to contain the checksum) is somehow always read as zero. We presume this is a hardware bug in the bridge part. The other, much more annoying way is "indirect mode", where each byte transmitted over the AUX channel has to be manually set up in the I2C registers of the bridge, just like we're already doing with DPCD transactions. Thankfully, we can reuse most of the DPCD code for this so it's not a lot of extra code. It's a bit slower but not as much as you'd expect (26ms instead of 18ms on my board), and the difference is not very relevant compared to common total times for display init. Also, some of the (previously unused) enum definitions for the AUX_CMD mode field of the bridge had just been plain wrong for some reason, and needed to be fixed to make this work.

DP link rates are reported in an array of LE16 values. The current code tries to parse them as 8-bit which doesn't get very far, causing us to always drop into the fallback path.

2020-10-09sc7180: Remove the delay to force hpd detection and always disable HPDVinod Polimera
HPD on this bridge chip is a bit useless. This is an eDP bridge so the HPD is an internal signal that's only there to signal that the panel is done powering up. But the bridge chip debounces this signal by between 100 ms and 400 ms (depending on process, voltage, and temperate). One particular panel asserted HPD 84 ms after it was powered on meaning that we saw HPD 284 ms after power on. Assume that the panel driver will have the hardcoded delay in its prepare and always disable HPD.
