/**
|
|
* @page devinfo_command
|
|
|
|
If called without arguments, devinfo shows a summary of the known
|
|
devices and drivers.
|
|
|
|
If called with a device path being the argument, devinfo shows more
|
|
default information about this device and its parameters.
|
|
|
|
Example from an MPC5200 based system:
|
|
|
|
@verbatim
|
|
barebox:/ devinfo /dev/eth0
|
|
base : 0x1002b000
|
|
size : 0x00000000
|
|
driver: fec_mpc5xxx
|
|
|
|
no info available for eth0
|
|
Parameters:
|
|
ipaddr = 192.168.23.197
|
|
ethaddr = 80:81:82:83:84:86
|
|
gateway = 192.168.23.1
|
|
netmask = 255.255.255.0
|
|
serverip = 192.168.23.2
|
