Hello all, I have a need to pass the u-boot version string to the operating system and I'm thinking at adding `u-boot,version` property storing `version_string` in it in the FDT `chosen` node.
Is this something that would be generally useful? Would be a patch like that acceptable in upstream u-boot? Is there any other obvious way to achieve something like that already implemented (using the cmdline would work without any code change, but probably not the nicest solution).
Any concern on this Tom? I'm asking you directly since you recently acknowledged another change [0] related to the chosen node.

To be honest, putting this in the "chosen" node feels odd. Traditionally device trees have a node dedicated to the firmware. For example Sun OpenFirmware systems had a "openprom" node with a "version" property. And OpenPOWER systems have an "ibm,firmware-versions" node.
