NOTES: - I make no attempt to try to share an "item" for all sc7180 based Chromebooks. Because of the revision matching scheme used by the Chromebook bootloader, at times we need a different number of revisions listed. - Some of the odd entries in here (like google,homestar-rev23 or the fact that "Google Lazor Limozeen without Touchscreen" changed from sku5 to sku6) are not typos but simply reflect reality. - Many revisions of boards here never actually went to consumers, but they are still in use within various companies that were involved in Chromebook development. Since Chromebooks are developed with an "upstream first" methodology, having these revisions supported with upstream Linux is important. Making it easy for Chromebooks to be developed with an "upstream first" methodology is valuable to the upstream community because it improves the quality of upstream and gets Chromebooks supported with vanilla upstream faster. This patch also adds a link to the Chromebook boot flow documentation to explain that Chromebooks don't use the scheme described for the Qualcomm bootloader. Signed-off-by: Douglas Anderson Reviewed-by: Matthias Kaehlcke --- The link added here will (obviously) not function until the documentation patch makes it to mainline. Presumably folks who want to read it in the meantime can find it pretty easily. If there's a better way to link this then please let me know. Changes in v2: - Add link to doc about how Chromebook devicetrees work. - Use a "description" instead of a comment for each item. - Use the marketing name instead of the code name where possible. .../devicetree/bindings/arm/qcom.yaml | 187 +++++++++++++++++- 1 file changed, 186 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/arm/qcom.yaml b/Documentation/devicetree/bindings/arm/qcom.yaml index 5c06d1bfc046..8ec0805f4996 100644 --- a/Documentation/devicetree/bindings/arm/qcom.yaml +++ b/Documentation/devicetree/bindings/arm/qcom.yaml @@ -90,6 +90,11 @@ description: | A dragonboard board v0.1 of subtype 1 with an apq8074 SoC version 2, made in foundry 2. + There are many devices in the list below that run the standard ChromeOS + bootloader setup and use the open source depthcharge bootloader to boot the + OS.
