To remain consistent with what is done with CPM2, let's link
CPM1 related parts to CONFIG_CPM1 instead of CONFIG_8xx

When something depends on both CPM1 and CPM2 we associate it
with CONFIG_CPM

Use of_property_read_u32 instead of the generic of_get_property to
simplify the code. In addition move the declaration of fs_baudrate
into get_baudrate because it's private to this function.

powernv marks it's halt and restart calls as __noreturn. However,
ppc_md does not have this annotation. Add the annotation to ppc_md,
and then to every halt/restart function that is missing it.

Additionally, I have verified that all of these functions do not
return. Occasionally I have added a spin loop to be sure.

Of_node_put supports NULL as its argument, so the initial test is not
necessary.

Suggested by Uwe Kleine-König.

The semantic patch that fixes this problem is as follows:

expression e;

-if (e)
   of_node_put(e);

<title>powerpc: Convert power off logic to pm_power_off</title>

<id>9178ba294b6839eeff1a91bed95515d783f3ee6c</id>
<content type='text'>
The generic Linux framework to power off the machine is a function pointer
called pm_power_off. The trick about this pointer is that device drivers can
potentially implement it rather than board files.

Today on powerpc we set pm_power_off to invoke our generic full machine power
off logic which then calls ppc_md.power_off to invoke machine specific power
off.

However, when we want to add a power off GPIO via the "gpio-poweroff" driver,
this card house falls apart. That driver only registers itself if pm_power_off
is NULL to ensure it doesn't override board specific logic. However, since we
always set pm_power_off to the generic power off logic (which will just not
power off the machine if no ppc_md.power_off call is implemented), we can't
implement power off via the generic GPIO power off driver.

To fix this up, let's get rid of the ppc_md.power_off logic and just always use
pm_power_off as was intended. Then individual drivers such as the GPIO power off
driver can implement power off logic via that function pointer.

With this patch set applied and a few patches on top of QEMU that implement a
power off GPIO on the virt e500 machine, I can successfully turn off my virtual
machine after halt.

<title>powerpc/fsl: fsl_soc: remove 'fixed-link' parsing code</title>

Parsing and registration of fixed PHY devices was needed with the use of
of_phy_connect_fixed_link() because this function was using the
designated PHY address identifier (first cell of the property) as the
address to bind the PHY on the emulated bus.

Since commit 3be2a49e5c08d268f8af0dd4fe89a24ea8cdc339 ("of: provide a
binding for fixed link PHYs") a new pair of functions has been
introduced which allows for dynamic address allocation of these fixed
PHY devices, but also parses the old 'fixed-link' 5-digit property.

Registration of fixed PHY early in platform code was needed because we
could not issue a fixed MDIO bus re-scan within network drivers. The
fixed PHYs had to be registered before the network drivers would call
of_phy_connect_fixed_link(). All of these caveats are solved now, such
that we can safely remove of_add_fixed_phys() now.
