AW: Read Barebox Infos from Linux

[Michael Graichen <michael.graichen@hotmail.com>]

Hey Ahmed and Sascha, 

Thanks for your reply. 

This is all meant to work with devicetree support. Not x86/efi systems?

Best regards 
Michael

That's what CONFIG_FS_PSTORE_CONSOLE does, see
https://www.barebox.org/doc/latest/filesystems/pstore.html

> Barebox version from within Linux?

Yes, check out /proc/device-tree/chosen/barebox-version

If you are curious what else barebox is fixing up into the device tree,
try of_diff - +

This will apply all DT fixups to a copy of the barebox device tree and
show a diff before and after, e.g.

chosen {
+       barebox-version = "barebox-2021.05.0-20220126-2";
+       bootargs = "console=ttymxc1,115200n8";
+       reset-source = "POR";
+       reset-source-instance = <0x0>;
+       bootsource = "/soc/bus@2100000/mmc@2198000";
};

Cheers,
Ahmad
