[PATCH 2/2] MCI: init device_node for MCI mainarea cdev

This fixes a regression, where boards specifying the environment path using the form device-path = &phandle, "partname:part" would be unable to find their env. This is due to of_find_path() switching to cdev_by_device_node() internally, which expects the device_node member of the main area cdev to

Messed up commit in master

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

[PATCH v2 9/9] fs: Add pstore filesystem

pstore is a persistent storage filesystem used for RAMOOPS. It is used to store console logs, panics, ftrace and other information in case of a crash/panic/oops/reboot. pstore is implemented for barebox as a read-only filesystem at the moment. It may be extended later on. The idea is to provide a
