In commit 1c0eaf0f56d6 ("powerpc/powernv: Tell OPAL about our MMU mode
on POWER9"), we added additional flags to the OPAL call to configure
CPUs at boot.
These flags only work on Power9 firmwares, and worse can cause boot
failures on Power8 machines, so we check for CPU_FTR_ARCH_300 (aka POWER9)
before adding the extra flags.
Unfortunately we forgot that opal_configure_cores() is called before
the CPU feature checks are dynamically patched, meaning the check
always returns true.
We definitely need to do something to make the CPU feature checks less
prone to bugs like this, but for now the minimal fix is to use
early_cpu_has_feature().

We want to use generic 8250 debug_ll code to get DEBUG_UNCOMPRESS
working and to simplify the code. The old debug_ll code is no longer
needed and the machine ID based detection is no longer used.
Note that for most part there's no need to keep DEBUG_LL enabled.
We now have CONFIG_SERIAL_EARLYCON working very early as long as
the kernel cmdline has "earlycon" in it and the board specific dts
file has chosen configured with with the port using stdout-path.

Provide the dynamic power coefficient of the big and little CPU
clusters. These numbers are currently in use on the Samsung Chromebook
Plus ("Kevin").
The power allocator thermal governor doesn't know how to do anything if
it doesn't get power parameters from its cooling devices (in this case,
CPUfreq). So this effectively enables the power-allocator governor.

The Gru device tree currently contains entries for the regulators
ppvar_bigcpu, ppvar_litcpu, ppvar_gpu and ppvar_centerlogic; however,
the regulators have not been enabled, due to the lack of binding and driver
support for keeping the over-voltage protection (OVP) at bay and
preventing unintended regulator shutdowns on voltage downshifts.
Now, the vctrl regulator driver has been merged, along with new bindings
for asymmetric settling time. The driver is OVP aware, it splits larger
voltage decreases in multiple steps when necessary and adds required
delays.
This change renames each of the aforementioned regulators to
<orig_name>_pwm and adds a new vctrl regulator named <orig_name>.
The vctrl regulators use the voltage of their corresponding PWM regulator
as control voltage. The OVP related values are empirical and stem from
the Chrome OS kernel tree.

optimizer turns it into a direct call.
