[OpenRISC] [PATCH 1/2] or1k: dts: Fix ethoc network configuration in or1ksim devicetree

[Stafford Horne]

This fixes several issues with the ethoc network device config.

Fisrt off, the compatible property used an obsolete compatibility
string; this caused the initialization to be skipped.  Next, the
register map was not given enough space to allocate ring descriptors,
this caused module initialization to abort.  Finally, we need to mark
this device as big-endian as needed by openrisc.

This was tested by me in qemu, the setup is documented on the qemu wiki:

[OpenRISC] [PATCH 2/2] or1k: dts: Add ethoc device to SMP devicetree

[Stafford Horne]

This patch adds the ethoc device configuration to the OpenRISC basic SMP
device tree config.  This was tested with qemu.

[OpenRISC] [PATCH 2/2] or1k: dts: Add ethoc device to SMP devicetree

[BAndViG]

Hello All.
I've ported these ethernet description for my Atlys-based SoC. Prior to it 
Linux were not able even to detect Marvell's PHY. With the modifications 
Marvell's PHY is detected correctly. However, I still can not  use ethernet 
connection. For example, If I try to execute "ping {ip-of-my-pc}" it reports 
"net eth0: TX: carrier sense lost". Perhaps, I have to configure correctly MDIO 
bus and PHY itself. Have anybody got an recommendation?

WBR
