class DevicetreeChosenNodeMatcherBase

Defined at line 270 of file ../../zircon/kernel/phys/lib/boot-shim/include/lib/boot-shim/devicetree.h

This matcher parses the 'chosen' node, which is a child of the root node('/chosen'). This node

contains information about the commandline, ramdisk and UART.

* The cmdline is contained as part of the string block of the devicetree.

* The ramdisk is represented as a range in memory where the firmware loaded it, usually a ZBI.

* The UART on the other hand, is represented as path(which may be aliased). Is the job of this

item to bootstrap the UART, which means determining which drItemiver needs to be used.

For more details on the chosen node please see:
