Raspbian and Fedora have decided to support the Pi3 in 32-bit mode for
now, so it's useful to be able to test that mode on an upstream
kernel.  It's also been useful for me to use the same board for 32-bit
and 64-bit development.

Compiling the DT file with W=1, DTC warns like follows:

Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property

Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.

The spear6xx doesn't have a pinctrl driver, since the pinmux is globally
defined through a single register, generally configured by the

Therefore, the pinctrl related properties in spear600-evb.dts are not

We found out that HW checksum generation only works from AST2500
onward. This disables it on AST2400 and removes the "no-hw-checksum"
properties in the device-trees. The problem we had wasn't related
to NC-SI.

Also rework the logic testing for that property so it can be used
to disable HW checksum generation and checking regardless of whether
NC-SI is used or not in case other variants out there need this.

Recently most nodes got labels to make them referenceable. The USB 3.0
nodes as well as the nodes for the SATA controllers were left out,
rectify the omission.

The labels "sataX" are already used by some boards for the SATA ports,
therefore use "ahciX" to label the SATA controller nodes.

To avoid potential confusion by labeling an USB3.0 controller "usb2" use
usb3_X as labels. This also coincides with the node names themselves
(usb@xxxxx vs usb3@xxxxx).
