[U-Boot] [Turris Omnia] Btrfs support status?

[Marek Behún]

Hello,

the Turris Omnia router uses btrfs as the main filesystem, from which
it also loads kernel and dts. We have an implementation in our internal
u-boot
(https://gitlab.labs.nic.cz/turris/turris-omnia-uboot/tree/master/fs/btrfs).

As I understand it, this code was already proposed for u-boot:
https://patchwork.ozlabs.org/patch/300593/ . Is this true? Why was it
not accepted? Does this code need to be rewritten, or something? Or is
there simply no interest in mainlining support for btrfs?

Thank you.
