When fixed-link phy is used subnode offset is used as phy address. This number is bigger then space allocated for bus structure (allocated via mdio_alloc). bus->phymap[] array has PHY_MAX_ADDR size (32). That's why writing bus->phymap[addr] where addr is < 0 or > PHY_MAX_ADDR is causing write to memory which can caused full U-Boot crash.
The patch is checking if address is in correct range.
