[OSS-Tools] [PATCH v4 0/3] improve barebox-state support on EFI system

[Michael Olbrich <m.olbrich@pengutronix.de>]

Hi,

so the discussion on the barebox ML resulted in a different binding for
this. Sascha has sent patches for that[1]. This is now mainline in Barebox.

So while this is 'v4' for this topic, all the patches except the last one
are actually different, so please drop the old series that is still present
in the next branch.

v2 had some Bugs that have been fixed in v3.
Added some improvements as suggested by Ahmad in v4.

In the device-tree it now looks like this:

----------------------------------------------------------------------
/ {
[...]
        state: state {
[...]
                backend = <&barebox_state>;
[...]
        };

        disk {
                compatible = "barebox,storage-by-uuid";
                uuid = "deadbeaf";

                partitions {
                        compatible = "fixed-partitions";
                        #address-cells = <2>;
                        #size-cells = <2>;

                        barebox_state: state@300000 {
                                label = "barebox-state";
                                reg = <0x0 0x300000 0x0 0x100000>;
                        };
                };
        };
};
----------------------------------------------------------------------

Regards,
Michael
