Add support for being able to set the learning attribute on port, and
make sure that the standalone ports start up with learning disabled.
We can remove the code in bcm_sf2 that configured the ports learning
attribute because we want the standalone ports to have learning disabled
by default and port 7 cannot be bridged, so its learning attribute will
not change past its initial configuration.

Flip the IVL_SVL_SELECT bit correctly based on the VLAN enable status,
the default is to perform Shared VLAN learning instead of Individual
learning.

When asking the ARL to read a MAC address, we will get a number of bins
returned in a single read. Out of those bins, there can essentially be 3
states:
- all bins are full, we have no space left, and we can either replace an
existing address or return that full condition
- the MAC address was found, then we need to return its bin index and
modify that one, and only that one
- the MAC address was not found and we have a least one bin free, we use
that bin index location then
The code would unfortunately fail on all counts.

The ARL {MAC,VID} tuple and the forward entry were off by 0x10 bytes,
which means that when we read/wrote from/to ARL bin index 0, we were
actually accessing the ARLA_RWCTRL register.

In preparation for migrating the EEE code from bcm_sf2 to b53, define the full

The code to enable Broadcom tags/headers is largely switch independent,
and in preparation for enabling it for multiple devices with b53, move
the code we have in bcm_sf2.c to b53_common.c

Implement the correct software reset sequence for 58xx devices by
setting all 3 reset bits and polling for the SW_RST bit to clear itself
without a given timeout. We cannot use is58xx() here because that would
also include the 7445/7278 Starfighter 2 which have their own driver
doing the reset earlier on due to the HW specific integration.

Since Broadcom tags are not enabled in b53 (DSA_PROTO_TAG_NONE), we need
to make sure that the IMP/CPU port is included in the forwarding
decision.
Without this change, switching between non-management ports would work,
but not between management ports and non-management ports thus breaking
the default state in which DSA switch are brought up.

In order to migrate the bcm_sf2 driver over to the b53 driver for most
VLAN/FDB/bridge operations, we need to add support for the "join all
VLANs" register and behavior which allows us to make a given port join
all VLANs and avoid setting specific VLAN entries when it is leaving the
bridge.

Add support for HW bridging by tying the ports together in the same port
VLAN mask when they belong to the same bridge, and isolating them to be
alone with the CPU port when they are not.
Propagate STP states from the bridge layer to the switch's HW mapping
when requested.

Adds support for FDB add/delete/dump using the ARL read/write logic and
the ARL search logic for faster dumps. The code is made flexible enough
it could support devices with a different register layout like BCM5325
and BCM5365 which have fewer number of entries or pack values into a
single 64 bits register.

This patch adds support for Broadcom's BCM53xx switch family, also known
as RoboSwitch. Some of these switches are ubiquituous, found in home
routers, Wi-Fi routers, DSL and cable modem gateways and other
networking related products.
This drivers adds the library driver (b53_common.c) as well as a few bus
glue drivers for MDIO, SPI, Switch Register Access Block (SRAB) and
memory-mapped I/O into a SoC's address space (Broadcom BCM63xx/33xx).
Basic operations are supported to bring the Layer 1/2 up and running,
but not much more at this point, subsequent patches add the remaining
features.
