When I read to my id u-boot report 0xffff and fail, but the device works pretty well skipping this testing. If I remember linux report the same issue.

Is the MII address of your PHY set correctly?

All MII-capable PHYs should have a working PHYSID1 register. If it doesn't, something is broken.

So I think the CONFIG_GENERIC_PHY name is misleading -- the test is generic enough as is. CONFIG_BROKEN_PHY would be better, if there's really no way to get your PHY to behave.

But note that if MDIO communication isn't working, autonegotiation won't work, and the speed and duplex settings will most likely be wrong. So I don't think simply #ifdefing out that sanity check is really going to solve any problems.

Yes I know but this is the situation:

- dm9161a - at91sam9260

When I try to read at phy id it reports 0xffff and linux too. I suppose that can be related to a broken phy. But seems to be broken on this read. I think that you have more experience, do you have an idea?
