"eth1: Could not attach to PHY" on MPC8349e-MITX

[Timur Tabi]

The Freescale MPC8349e-MITX reference board has two TSECs, the second
of which (eth1) is attached to a Vitesse 7385 5-port switch.

Using the latest U-Boot, Kernel, and device tree, I cannot bring up
eth1.  When I try, I get this message:

[root at tintin root]# ifconfig eth1 up
0:01 not found
eth1: Could not attach to PHY
SIOCSIFFLAGS: No such device

Unfortunately, I don't even know what this means.

I believe my network configuration is correct.  Here's what ifconfig
says about eth1:

eth1      Link encap:Ethernet  HWaddr 00:E0:0C:00:8C:02
          inet addr:192.168.2.141  Bcast:192.168.255.255  Mask:255.255.0.0
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Base address:0x4000

eth1 does work in U-boot, so I know it can be made to work (and I know
the 7385's firmware is uploaded), I just don't know what needs to be
done in Linux.
