This patch set v2 addresses the comment about registering a MAC address
for an Ethernet port. The consequence is that there are now only five
patches.
This patch set adds support for the GEIP DA923RC board.
It extends SOC support to the MPC8544 and enables the DDR driver.
The gianfar driver support is updated so that the board MAC address
can be passed to the driver.
Renaud Barbier (5):
ppc: mpc85xx: mpc8544 support
ppc: mpc85xx: define Ethernet port count
ppc: mpc85xx: enable DDR driver
ppc: DA923RC: add board support
ppc: mpc85xx: build directives

Definitions are added to support the mpc8544 CPU.
The function returning the I2C bus frequency is updated
to take into account the mpc8544 specific clock ratio.

Because the port count is different between the MPC8544 and
existing CPU support, the Ethernet port count is defined on
a per CPU basis.
Accordingly, the TBI PHY initialisation code is updated.

The use of the DDR driver as well as early I2C support is
enabled for board initialising their memory through SPD EEPROM
data.
A SOC specific function returning the DDR bus frequency
is added for the DDR driver to translate DDR timings to
register values.

I think because the machine is still running from SRAM or flash here and
I2C is needed to read out the SPD EEPROM for setting up SDRAM.

I just wonder that this function is called from initcall context. I
would assume the initcalls start running from SDRAM. I wonder how this
works.

At this stage the code has been relocated in memory. The function below
is called early in the initcall table after busses initialization.
I am looking into this.

Note that here the code enables a CPU function that is, the whole block
of pins is enabled to be used as GPIO out pin. This does not specify the
pins direction but the pins function.
Of course, this can be wrap in a function specific to the CPU.

so this should use pinctrl API

The pinctrl support seems oriented at enumerating and naming pins as
well as controlling pin properties (direction, drive strength,...) on
an individual basis.
In the code above, it is simply enabling the GPIO out function of the CPU.
For controlling individual GPIO pins, you suggestion of using the GPIO
API seems the right one to do what I need to do.
Thanks.

In order to use the I2C API would I not need to register my i2c bus
first? This only happens later in the initcall list with device-initcall.

Yes, You would have to have your i2c bus registered. Can't you move the
above to late_initcall?

I just did the following experiment:
Move the code to device_initcall after the I2C registration and use the
I2C API. Using the I2C API worked. However, when booting the board model
is a NULL strings.
So next I will check whether I can register the I2C device either in the
postcore_initcall or when doing the console_initcall.
Renaud.

Probably a bad idea if device registration relies on the previous
initcall: fs_initcall.

I found a way to do it. This implies to:
- register the i2c-imx driver at the postcore initcall level.
- register the board i2c bus at the postcore initcall level
and perform the rest of the board initialization.
The i2c-imx driver is shared between architectures. If you do not
foresee any side-effects on the ARM architecture and this is acceptable
to you, I would like to submit a patch including this solution.
Otherwise, I would prefer to keep the current implementation.
Regards,
Renaud.

Could you set the model to a superset of both possible boards initially,
something like DA923RC/GBX460? Then set the correct board type in a
late_initcall. The only thing affected is the printing of the board type
in the banner, right?

Indeed, in this particular example, the only thing affected is the
printing of the board name.
However, reading the I2C early is not just for the board name.
We have other variants of the board coming that may require minor
adjustment (for instance DDR timing tuning) or early configuration.
Renaud.

I assume the timing has to be adjusted before the DDR can be used,
right? If so, then you have no other choice but to use some early i2c
stuff. Make sure though that it is only used as little as possible.
