In preparation for the introduction of more than 2 CPs in upcoming
SoCs, it makes sense to move away from the "CP master" (cpm) and "CP
slave" (cps) naming, and use instead cp0/cp1.
This commit is the result of:
sed 's%cpm%cp0g%' arch/arm64/boot/dts/marvell/*
sed 's%cps%cp1g%' arch/arm64/boot/dts/marvell/*
So it is a purely mechaninal change.

One concept of Marvell Armada 7K/8K SoCs is that they are made of HW
blocks composed of a variety of IPs (network, PCIe, SATA, XOR, SPI,
I2C, etc.), and those HW blocks can be duplicated several times within
a given SoC. The Armada 7K SoC has a single CP110 (so no duplication),
while the Armada 8K SoC has two CP110. In the future, SoCs with more
than 2 CP110s will be introduced.
In current kernel versions, the master CP110 is described in
armada-cp110-master.dtsi and the slave CP110 is described in
armada-cp110-slave.dtsi. Those files are basically exactly the same,
since they describe the same hardware. They only have a few
differences:
- Base address of the registers is different for the "config-space"
- Base address of the PCIe registers, MEM, CONF and IO areas were
different
- Labels (and phandles pointing to them) of the nodes were different
("cpm" prefix in the master CP, "cps" prefix in the slave CP)
This duplication issue has been discussed at the DT workshop [1] in
Prague last October, and we presented on this topic [2]. The solution
of using the C pre-processor to avoid this duplication has been
validated by the people present in this DT workshop, and this patch
simply implements what has been presented.
We handle differences between the master CP and slave CP description
using the C pre-processor, by defining a set of macros with different
values armada-cp110.dtsi is included to instantiate one of the master
or slave CP110.
There are a few aspects that deserve additional explanations:
- PCIe needs to be handled separately because it is not part of the
config-space {...} node, since it has registers outside of the
range covered by config-space {...}.
- We need to defined CP110_BASE, CP110_PCIEx_BASE without 0x, because
they are used for the unit address part of some DT nodes. But since
they are also used for the "reg" property of the same nodes, we
have an ADDRESSIFY() macro that prepends 0x to those values.
We compared the resulting .dtb for armada-8040-db.dtb before and after
this patch is applied, and the result is exactly the same, except for
a few differences:
- the SDHCI controller that was only described in the master CP110 is
now also described in the slave CP110. Even though the SDHCI
controller from the slave CP110 is indeed not usable (as it isn't
wired to the outside world) it is technically part of the silicon,
and therefore it is reasonable to also describe it to be part of
the slave CP110. In addition, if we wanted to get this correct for
the SDHCI controller, we should also do it for the NAND controller,
for which the situation is even more complicated: in a single CP110
configuration (Armada 7K), the usable NAND controller is in the
master CP110, while in a dual CP110 configuration (Armada 8K), the
usable NAND controller is in the slave CP110. Since that would add
a lot of additional complexity for no good reason, and since the IP
blocks are in fact really present in both CPs, we simply describe
them in both CPs at the DT level.
- the cp110-master and cp110-slave nodes are now named cpm and
cps. We could have kept cp110-master and cp110-slave, but that
would have required adding another CP110_xyz define, which didn't
seem very useful.
Note that this commit also gets rid of the armada-cp110-master.dtsi
and armada-cp110-slave.dtsi files, as future SoCs will have more than
2 CPs. Instead, we instantiate the CPs directly from the SoC-specific
.dtsi files, i.e armada-70x0.dtsi and armada-80x0.dtsi.

We are currently using the cell-index DT property to assign SPI bus
numbers. This property is specific to the spi-orion driver, and
requires each SPI controller to have a unique ID defined in the Device
Tree.
As we are about to merge armada-cp110-master.dtsi and
armada-cp110-slave.dtsi into a single file, those cell-index
properties that differ between the master CP110 and the slave CP110
are a difference that would have to be handled.
In order to avoid this, we switch to using the "aliases" DT node to
assign a unique number to each SPI controller. This is more generic,
and directly handled by the SPI core.
