The driver looks for a storage device matching the + given UUID and when found registers a new cdev for the device. + + This driver solved a very specific problem. On EFI the storage devices + are not connected to any device tree node. barebox-state however expects + a node to use as its backend. The obvious solution would be to create + a partition with a specific partuuid and use that for state, in our + special usecase though the storage device is partitioned with a MBR + which doesn't have any space left to create a new partition. As this + driver parses the of partition binding we can use that to create + a partition in an unallocated are of the disk which is then used for + state. + + This driver has the problem that it depends on storage devices which + are not described in the device tree. This means it cannot work with + deep probe. This is not a problem on EFI though. It's a special purpose + driver, it's not recommended for general use. + endmenu |
