Messed up commit in master

[Lucas Stach]

Hi Sascha,

I've just stumbled across a messed up commit that landed in barebox
master. It seems you squashed other unrelated commits into commit
e7a8519963fcb235a123dfe5e7dd59d6fb2eaf9e (ARM: mx6sx-sabresdb: set
proper hostname).

I know its against the master stability rules, but I think it would be
justified to split this commit properly and re-push a fixed master.

Regards,
Lucas
