of_partition: devfs_add_partition returns an error pointer ...

Check for the return value of devfs_add_partition with IS_ERR.
Otherwise we dereference a NULL pointer when devfs_add_partition
fails.

ENC28J60 is a stand-alone Ethernet controller with SPI Interface
and integrated 10BASE-T PHY.

This driver was ported from linux-3.15.

The most notable barebox driver version changes:
  * add device tree support;
  * drop netif_msg_*() debug level checking;
  * use IF_ENABLED for checking CONFIG_ENC28J60_WRITEVERIFY;
  * add mii_bus support.

DT PCI address translation needs a special handling. This imports
the corresponding translator into of/address.c but makes it selectable

for device_type property set to "pci".

net: orion: generate unique port device names ...

Marvell Orion ethernet IP originally is multi-port capable, but SoCs
using the IP usually have multiple single-port controllers built in.
Currently, orion-gbe driver registers each port device with a constant
name, which causes a name conflict with multiple controller instances.

This patch uniquifies port device name generation by prepending
controller's base register address to resolve the name conflict.

The current code counts the eraseregions a new partition spans and
sets the partitions number of eraseregions accordingly, but the code
forgets to allocate and fill in the eraseregions for the partition
mtd device. This makes the erase operation crash with a NULL pointer
exception.
This patch fixes this with the same approach the kernel uses: Set
the number of eraseregions to 1 unconditionally and the eraseregion
size to the maximum of the eraseregions found in the partition.
