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.

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.

We have an implementation for non-FSP systems now, and we shouldn't be
calling that from code in an fsp/ directory, so move op_display() to a
platform function.

Segregate the BMC platform configuration into hardware and software
components. This allows population of platform default values for
hardware configuration that may no-longer be accessible by the host.

On BMC machines, we have slot tables of built in PHBs, slots and devices
that are physically present in the system (such as the BMC itself). We
can use these tables to check what we *detected* against what *should*
be in the system and throw an error if they differ.
We have seen this occur a couple of times while still booting, giving the
user just an empty petitboot screen and not much else to go on. This
patch helps in that we get a skiboot error message, and at some point
in the future when we pump them up to the OS we could get a big friendly
error message telling you you're having a bad day.

An out of tree platform (p8dtu) uses a different IPMI OEM command
for IPMI_PARTIAL_ADD_ESEL. This exposed some assumptions about the BMC
implementation in our core code.
Now, with platform.bmc, each platform can dictate (or detect) the BMC
that is present. We allow it to be set at runtime rather than purely
statically in struct platform as it's possible to have differing BMC
implementations on the one machine (e.g. AMI BMC or OpenBMC).

Currently, most astbmc platforms do their own call to prd_init(), but
garrison is out-of-sync.
This change moves the prd_init call to astbmc_early_init, so we don't
need to enable it on every platform.

Presently abort() function is not working on BMC based machine. System
hangs after abort/assert call. We have to reboot machine from BMC (IPMI
command or BMC console).
This patch introduces attention functionality for BMC based machine.
It logs eSEL event that contains OPAL version, file info and backtrace.
And calls cec_reboot... which takes care of rebooting host.
Note:
- This patch uses ipmi_queue_msg() instead of ipmi_queue_msg_sync() as
we are having some issues with sync path. This will resolved once we
sort out [1].
- This patch calls cec_reboot to reboot machine after logging eSEL event.
It queues IPMI message and bt_poll() should be working until we pass
reboot IPMI message to BMC. Hence we have while loop with time_wait_ms().
Alternatively we can use xscom_trigger_xstop().. but it will stop
immediately and eSEL logging fails.

This adds support for the HW SerIRQ deserializer of the P8 LPC
bridge which is properly wired up on Naples. It also adds support
for detecting and reporting LPC error interrupts on all P8s.
On most platforms (Rhesus is the exception here due to the way it
lets Linux handle the UART interrupts directly), we modify the
device-tree to properly represent the LPC controller as a cascaded
interrupt-controller and the "interrupts" property of LPC devices
to contain the actual LPC interrupt number for the device.
We add a mechanism for drivers to register specific LPC interrupts,
and a "workaround" for pre-Naples P8 which platforms can use to call
all of them for when the external FPGA based deserializer is used.
There's also a callback on LPC resets which isn't used yet, we need
a bit more work on the general LPC error handling, but it can be
done a separate patches.

Implement start_preload_resource and resource_loaded platform functions
for astbmc machines (palmetto, habanero, firestone).
This means we start loading kernel and initramfs from flash much earlier
in boot, doing things like PCI init concurrently so that by the time
we go to boot the payload, it's already loaded.
Implementation is a simple queue with a job running on another CPU doing
the libflash calls.
