SPDX makes it a simpler diff.
I have audited the commit history of each file to ensure that they are
exclusively authored by IBM and thus we have the right to relicense.
The motivation behind this is twofold:
1) We want to enable experiments with coreboot, which is GPLv2 licensed
2) An upcoming firmware component wants to incorporate code from skiboot
and code from the Linux kernel, which is GPLv2 licensed.
I have gone through the IBM internal way of gaining approval for this.
The following files are not exclusively authored by IBM, so are *not*
included in this update (I will be seeking approval from contributors):

Use Software Package Data Exchange (SPDX) to indicate license for each
file that is unique to skiboot.
At the same time, ensure the (C) who and years are correct.

This patch adds support to read u64 sensor values. This also adds
changes to the core and the backend implementation code to make this
API as the base call. Host can use this new API to read sensors
upto 64bits.
This adds a list to store the pointer to the kernel u32 buffer, for
older kernels making async sensor u32 reads.

Add support to parse and export OCC inband sensors which are copied
by OCC to main memory in P9. Each OCC writes three buffers which
includes one names buffer for sensor meta data and two buffers for
sensor readings. While OCC writes to one buffer the sensor values
can be read from the other buffer. The sensors are updated every
100ms.
This patch adds power, temperature, current and voltage sensors to
/ibm,opal/sensors device-tree node which can be exported by the
ibmpowernv-hwmon driver in Linux.

Currently, we are hijacking the last bit of the resource field of the
sensor handler to differentiate the sensor families and route the
opal_sensor_read() call to the appropriate component.
Let's reserve the last 3bits and provide an API to set the sensor
family for current use and future use. This gives us a maximum of 8
families and 32 resource classes. The FSP uses 15, so we should be
fine for a while.

This patch adds a new sensor family for Digital Temperature Sensors
and a new resource class to capture the core temperatures.
Each core has four DTS located in different zones (LSU, ISU, FXU, L3).
The max of the four temperatures is computed and returned for the core
as well as a global trip point value. This is based on the meltbox tool.

This patch introduces an initial framework to define a sensor_read
operation per platform. It also proposes a few helper routines to
work on the sensor 'handler' which identifies a sensor and attribute
in the OPAL_SENSOR_READ call.
