When the cape manager is built-in + the kernel image, the firmware loader cannot find the files + before the rootfs is mounted. This parameter controls the + period with which the boot state is checked in that case. + +There's a sysfs control interface which is defined at the ABI documentation +area. + +Theory of operation: +-------------------- + +On driver probe the I2C EEPROM of the baseboard is read and information about +the current baseboard is retrieved. This information includes the mapping from +baseboard board name to DT friendly compatible string. I.e. the "A335BONE" board +name from EEPROM is mapped to the "ti,beaglebone" compatible string which should +be present in the dtbo to be loaded. + +Afterwards the EEPROMs declared in each slot are probed, and the EEPROMs found +are decoded keeping track the cape part-number and version data. + +Using the part-number and version a firmware file is requested (the firmware +file requested is -.dtbo). + +The dtbo is unflattend and the resulting device tree is matched against a +compatible baseboard, and in case of multiple parallel loading capes the +priorities defined are honored. That means that when there are multiple capes +being loaded in parallel the ones with the lowest priority number are loaded +first. + +Applying the device tree overlay makes the cape operational, as if it was part +of the kernel's booting device tree. diff --git a/Documentation/printk-formats.txt b/Documentation/printk-formats.txt index b784c27..5bf7026 100644 --- a/Documentation/printk-formats.txt +++ b/Documentation/printk-formats.txt @@ -309,10 +309,40 @@ Command from struct task_struct Passed by reference. +Device tree nodes: + + %pO[fnpPcCFr] + + For printing device tree nodes.
