net: smc1111: add a quirk for pxa pxa27x platforms ...

As hinted in the linux kernel driver, pxa platforms such as mainstone,
stargate and idp have a broken design, where half-word writes not
aligned to a word address are not working.

This patch is a taking back the half-word write accessor for this
specific case from the linux kernel.

pci: make sure to activate devices on the root bus ...

Commit b8a1bb1dd215 (pci: defer device registration until after bridge setup)
changed the activation order of devices, so that bridges above the devices could
be configured properly before activating the devices below. This commit failed
to acknowledge that there may be devices located directly on the root bus without
any bridge in between and so those devices would never get enabled.

state: add framework for persistent state handling ...

This patch adds a framework to describe, access, store and restore a set of
variables. A state variable set can be fully described in a devicetree node.
This node could be part of the regular devicetree blob or it could be an extra
devicetree solely for the state. The state variable set contains variables of
different types and a place to store the variable set.

For more information see:
    Documentation/devicetree/bindings/barebox/barebox,state.rst
