X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=f0d6e29f97b3d59b3a82149df657d15b1e3eb004;p=u-boot.git

test/py: mii: Add tests for mii command

Add below test cases for mii commands:
mii_info -To display MII PHY info
mii_list - To list MII devices
mii_set_device - To set MII device
mii_read - To reads register from MII PHY address
mii_dump - To display data from MII PHY address

+# should be skipped. For example: Missing PHY device
+env__mii_device_test_skip = True
+
+# Setup env__mii_device_test to set the MII device names. Test will be skipped
+# if env_mii_device_test is not set
+env__mii_device_test = {
