The MIPS CPC (Cluster Power Controller) is setup during boot and can take
its configuration from the devicetree. This is currently not possible
because the cpc probing happens before dt initialization. Call order
during startup is:
setup_arch()
prom_init() <- our function
mips_cpc_probe()
smp_stuff()
arch_mem_init()
device_tree_init() <- our function
unflatten_and_copy_device_tree()
To avoid ugly hacking and support a clean devicetree relocate the cps/smp
stuff to device_tree_init(). This is basically the same location as in
generic mips initialization.

All kernel symbols are automatically refreshed by
`make kernel_oldconfig CONFIG_TARGET=target` and
`make kernel_oldconfig CONFIG_TARGET=subtarget`.

This is a preparation for 6.12 kernel support. It can help us
track the files history by using the Git tool.

Manually move the common NVMEM Kconfig symbols to the shared
config file and disable them for the mikrotik subtarget. Other
changes are automatically completed by `make kernel_oldconfig`.
This is a preparation for introducing the 6.12 kernel support.

Since the early beginning of the Realtek DSA driver there is an uncovered
locking issue between the standard (parent) mdio bus and the DSA (child)
mdio bus. This comes from the fact that the DSA bus simply links to the
parent read and write functions and calls them directly. This leads to
the following lock issue.
- Child bus calls phy_read/write functions and uses its internal lock
- Parent bus calls phy_read/write functions and uses its internal lock
It becomes clear that critical section can be accessed twice without
knowing that a operation from the other bus is currently active. This
can lead to critical malfunctions because the mdio driver needs a lot of
internal magic to get page selection done right. Effects are:
- The original page is lost after a phy_write/read_paged() call
- dmesg like "Realtek RTL8218B (external) rtl838x slave mii-0:00:
Expected external RTL8218B, found PHY-ID 6b23"
Other DSA drivers simply use the read/write functions from the parent bus
and thus avoid locking issues. Do it the same way.

Before generating the factory image, check if the input file
exists. Fix the build error when sysupgrade image is too big:

There are currently two power functions for the RTL8214FC in the driver
- rtl8380_rtl8214fc_on_off(): powers on/off both ports
- rtl8214fc_power_set(): powers on/off fibre or copper individually
While it seems obvious to merge these, one of them uses extended register
29 and the other register 30 to achieve the update. From looking at the
GPL source drops both methods exist with exactly the same operations. So
where to go from here? The descision was made based on:
- register 30 is only used during patching, 29 during normal operation
- Avoid raw page if possible to use function for RTL839x
So the attached patch was created. The result in the power down bits
was compared for the two old and the new implementation. Result is
always the same.

The RPi upstream repo switched to the upstream SDHOST driver some time ago, so
it's time to do the same in our configs.

Cleanup the code of the RTL83xx packet receive interrupt handler. Not
only for better readability but to avoid inconsistencies and stalls on
the RTL839x targets.
The current implementation seems to come from the GPL source code.
Calling the existing cleanup() function inside the interrupt context
without any locks conflicts with SMP & NAPI polling and makes things
worse instead of giving any benefit. Simply ignore RX buffer overruns
and let the device handle packet dropping itself.
