I’m using the in-kernel live device tree to represent my hardware device state. so CONFIG_OF_DTB_BLOB for the first case, and CONFIG_OF for the second. Up to now we bundle those two together. > Rob > Regards — Pantelis >> + help >> + This option enables the device tree infrastructure. >> + If is automatically selected by platforms that need it, but can >> + be enabled manually to increase compile-coverage. >> >> menu "Device Tree and Open Firmware support" >> depends on OF >> -- >> 1.9.1 >> >> -- >> To unsubscribe from this list: send the line "unsubscribe devicetree" in >> the body of a message to majordomo@xxxxxxxxxxxxxxx >> More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
