> 主题: [PATCH] vexpress/v8: Add support for SMSC91C111 integrated MAC and PHY module
> 
> 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.

> 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.

That's great!
