Several inline functions in this file reference undefined functions in U-Boot. For example: atomic-long.h:73:9: warning: implicit declaration of function 'atomic64_sub_and_test' atomic-long.h:80:9: warning: implicit declaration of function 'atomic64_dec_and_test' atomic-long.h:87:9: warning: implicit declaration of function 'atomic64_inc_and_test' Handle this the same as the 32 bit build by wrapping these functions in a __UBOOT__ check.
