Hi Robert, Instead of trying to port the patch to u-boot, I updated my kernel from the BBB stock v3.8.13-bone47 to the latest v3.8.13-bone70. Then re-doing the power on/off test right now. Currently there are about 200 times power cycling and 8 times u-boot reported "Phy 0 not found". But for all those 8 times the v3.8.13-bone70 kernel successfully started the Ethernet interface.
With the stock v3.8.13-bone47 kernel version, every time u-boot reports the "Phy 0 not found" error, then kernel can not successfully start the Ethernet interface either. So seems that this problem is solved in the v3.8.13-bone70 kernel version.
