[U-Boot] ARM breakage

[Tom]

After merging with u-boot/master
Multiple targets are fixed by getenv_IPaddr

However, i believe this may have broken an equal number of arm targets
On regression testing there are multiple failures with this error

smc91111_eeprom.c:33: error: redefinition of 'struct eth_device'
make[1]: *** [ .. build/examples/standalone/smc91111_eeprom.o] Error 1
