Joel,

I tried to pull this into the greater OpenBMC build at:
    https://gerrit.openbmc-project.xyz/#/c/159/

Good news: it compiles fine and gets to userspace with network!  Bad
news: lots of other things are broken.

My first observations:

* The host tty has changed from S5 to S4?
    Aug 09 21:52:37 barreleye systemd[1]: Found device /dev/ttyS4.
    Aug 09 21:52:41 barreleye obmc-console-server[588]: obmc-console-server:
        Can't access attribute sirq on device ttyS5: Permission denied
    Aug 09 21:52:41 barreleye obmc-console-server[588]: obmc-console-server:
        Can't access attribute lpc_address on device ttyS5: Permission denied
    Aug 09 21:52:41 barreleye obmc-console-server[588]: obmc-console-server:
        Can't read tty termios: Input/output error

* There might be some 'startup_hacks' to remove in skeleton:
    Aug 09 21:53:27 barreleye system_manager.py[606]:
        /usr/sbin/startup_hacks.sh: line 7:
        /sys/devices/platform/ahb/ahb:apb/1e787000.vuart/sirq: Permission denied
    Aug 09 21:53:27 barreleye system_manager.py[606]:
        /usr/sbin/startup_hacks.sh: line 8:
        /sys/devices/platform/ahb/ahb:apb/1e787000.vuart/lpc_address: Permission
        denied
    Aug 09 21:53:27 barreleye system_manager.py[606]:
        /usr/sbin/startup_hacks.sh: line 9:
        /sys/devices/platform/ahb/ahb:apb/1e787000.vuart/enabled: Permission
        denied

* i2c and LEDs seems to be broken in general.
    Aug 09 21:53:33 barreleye system_manager.py[606]: sh:
        /sys/class/i2c-adapter/i2c-3/3-0050/online: No such file or directory
    Aug 09 21:53:33 barreleye system_manager.py[606]: sh:
        /sys/class/i2c-adapter/i2c-3/3-0050/online: No such file or directory
    Aug 09 21:53:37 barreleye system_manager.py[606]: No LEDs present in the
        system

    Also, no /sys/class/i2c-adapter at all and no dmesg about i2c.
    Maybe missing in kernel config somehow?  /sys/class/leds and
    /sys/class/hwmon are both empty.

* pinctrl problems when we try to set up GPIOs
    aspeed-g4-pinctrl 1e6e2000.syscon:pinctrl at 1e6e2000: request() failed for
    pin 138
    aspeed-g4-pinctrl 1e6e2000.syscon:pinctrl at 1e6e2000: pin-138
    (1e780000.gpio:458) status -22
    aspeed-g4-pinctrl 1e6e2000.syscon:pinctrl at 1e6e2000: request() failed for
    pin 34
    aspeed-g4-pinctrl 1e6e2000.syscon:pinctrl at 1e6e2000: pin-34
    (1e780000.gpio:354) status -22
