Rename linux-obmc to linux-aspeed and move to the Aspeed
layer. Like recipes for u-boot forks, recipes for kernel
forks in support of different SOCs are typically provided
in the BSP supporting the SOC.
Moved a number of phosphor-isms out of the kernel recipe and put
those in a bbappend in aspeed-layer/bbappend.
Removed COMPATIBLE_MACHINE setting. We simply use PREFERRED_PROVIDER
in machine configuration files to set the default kernel recipe.
Tested: Booted spoon/palmetto images using QEMU

This option adds sysfs entries for watchdog devices. We need this so
that we can access the bootstatus sysfs file to indicate whether or not
the BMC has switched chips.

This updates the kernel to include the ASPEED DRM driver.
Note that the defconfig update has no affect on the I2C support; it
drops out only due to being selected by other dependencies.

Note that the 4.13 branch is EOL'd by the Linux community, and as such
should not be used for any products beyond development.
React to removal of occ hwmon instances from device trees with a
new startup/shutdown mechanism for phosphor-hwmon.
To fix this, a helper script will be used to start the service that
will pass the service the device tree name if it is present, or the
udev device path if it isn't. This script will still run from the
udev rule as before, but it will stop and start the service itself
without using the SYSTEMD_WANTS attribute.
As the path to the hwmon environment file matches the service
template argument, the paths for the OCC .conf files need to change
to match the device path instead of the previous device tree path.
Note that the pure device path would have the hwmon instance number
in it, but since that can't be known ahead of time it is stripped
off by the script that starts the service.
In addition, the pure device path for the OCCs contain several
':'s, meaning the associated environment files would also need to.
However, Yocto/Bitbake cannot handle a ':' in a file path, so they
are converted to '--'s by the script that starts the service and
phosphor-hwmon will convert them back internally when it starts.
The service file also needed some changes now that the service
lifetime is no longer controlled by systemd via SYSTEMD_WANTS.
This script will be called by a udev rule to start and
stop phosphor-hwmon when the hwmon device driver is started
and stopped.
It is passed both the device path and the OF_FULLNAME device
tree attribute. If OF_FULLNAME is present, it will start the
service with that as its template argument, otherwise it will
use the device path. This is to handle devices that aren't in
the device tree so they won't have OF_FULLNAME.
If a '/hwmon/hwmonN' is in the path it is removed, as this path
is also used as a path to an environment file and so must be
known ahead of time, which the hwmon instance N is not.
If there is a ':' in the path name, it is converted to a '--'.
Yocto/Bitbake cannot handle a ':' in file paths.

The current uuid generation method just export the machine-id,
it does not match the systemd description
(https://www.freedesktop.org/software/systemd/man/machine-id.html):
This ID uniquely identifies the host. It should be considered
"confidential", and must not be exposed in untrusted environments,
in particular on the network. If a stable unique identifier that is
tied to the machine is needed for some application, the machine ID
or any part of it must not be used directly.
Backport the new sd_id128_get_machine_app_specific from systemd 233,
to replace the old uuid generation method.

This bumps the kernel to include a port of the FSI I2C driver from the
FSP. It drives the I2C master in the CFAM logic of the host processor
over FSI. This driver is being rewritten to be a proper i2c bus driver,
and as such will be removed once that driver is functionally equivalent.
There is also a fix for the Zaius UART.

- FSI changes
* Merge v1 of the FSI patchset as sent to lkml
* Merge Jeremy's raw driver for slave address-space access
* Define pins in Palmetto DTS
* Build the FSI SCOM driver for both ast2400 and ast2500 systems. The
driver has not been enabled in the device tree so it will not affect
any sytems at this stage. We will enable systems as the userspace
changes are made to support the kernel driver.
- Zaius
* Enable LPC to AHB mapping for flash access
- Update the ast2400 systems with the correct amount of RAM
* They systems have 512MB, minus the 16MB framebuffer, but our device
tree restricted them to 256MB.
* We now set them to 512MB with a 16MB no-map reservation at the top
for RAM for the PCI framebuffer

The kernel driver for the iBT interface has landed upstream. In the
review process, the location of the device node was changed, as was the
naming of the ioctls and the kconfig symbol.
This change moves to the new version of btbridge, which brings in
autotools support from Matt Barth and a port to the new kernel driver
from Cédric Le Goater. The .bb file is modified to support the autotools
dependencies.
Convert build process to autotools
replace bt_host by bt_bmc
add a --device option
Corrected resulting errors from -Wall & -Werror.
We update the ast2400 and ast2500 defconfigs with the new config symbol,
and bump the kernel to the latest version. The kernel changes clean up
the old driver, and add the new one, including device tree changes.
