Since 741e58e0fc8e (Create a .cfg file containing the CONFIG options used to build), all the Blackfin boards fail to build if the parallel (-j) option is passed.
$ make -s bf506f-ezkit_defconfig # # configuration written to .config # $ make -j8 CROSS_COMPILE=bfin-elf- scripts/kconfig/conf --silentoldconfig Kconfig CHK include/config.h UPD include/config.h GEN include/autoconf.mk GEN include/autoconf.mk.dep CHK include/config/uboot.release CHK include/generated/timestamp_autogenerated.h UPD include/generated/timestamp_autogenerated.h CFG u-boot.cfg include/asm-offsets.h:3:43: fatal error: generated/generic-asm-offsets.h: No such file or directory compilation terminated. make: *** [u-boot.cfg] Error 1
When parsing header files for defined CONFIG options, DO_DEPS_ONLY must be defined to exclude generated headers that might not have been available yet.
