This patch enables ethernet support in ARMv8 foundation model. The ARMv8 foundation model supports a SMSC91C111 integrated MAC and PHY module which is present at base address 0x01A000000.
The patch has been tested on ARMv8 foundation model by running ping/tftp between the foundation model and the host PC via a bridged network.
Signed-off-by: Bhupesh Sharma bhupesh.sharma@freescale.com
This patch is based on the ARMv8 support related patches sent out by David Feng. The V5 of this patchset from David can be found here: http://u-boot.10912.n7.nabble.com/PATCH-v5-0-4-arm64-patch-td161939.html
To test the ethernet functionality on a ARMv8 foundation model:
Launch the model with BRIDGED networking option: --network=bridged
This will create an ethernet interface (eth0) inside the model and an interface ARM0 on the Host PC.
Assign appropriate IP addresses: ~ On Host: $ ifconfig ARM0 10.10.10.11 ~ On foundation model: VExpress# setenv ipaddr 10.10.10.10 VExpress# setenv gatewayip 10.10.10.11 VExpress# setenv serverip 10.10.10.11
Now try out ping/tftp tests.
