[U-Boot] AM335x: env_{flash,nowhere} compile conflict

[Mark Jackson]

I'm struggling to work out why I get the following compile error:-

arm-linux-ld.bfd  -r -o /home/mpfj/uboot/u-boot/spl/common/libcommon.o  /home/mpfj/uboot/u-boot/spl/common/cmd_nvedit.o /home/mpfj/uboot/u-boot/spl/common/console.o /home/mpfj/uboot/u-boot/spl/common/dlmalloc.o /home/mpfj/uboot/u-boot/spl/common/env_common.o /home/mpfj/uboot/u-boot/spl/common/env_flash.o /home/mpfj/uboot/u-boot/spl/common/env_nowhere.o /home/mpfj/uboot/u-boot/spl/common/image-fdt.o /home/mpfj/uboot/u-boot/spl/common/image.o /home/mpfj/uboot/u-boot/spl/common/memsize.o /home/mpfj/uboot/u-boot/spl/common/miiphyutil.o /home/mpfj/uboot/u-boot/spl/common/stdio.o /home/mpfj/uboot/u-boot/spl/common/xyzModem.o

I have 2 custom entries in the boards.cfg file:-

nanobone                     arm         armv7       nanobone            newflow        am33xx      nanobone:NOR_BOOT
nanobone_sdboot              arm         armv7       nanobone            newflow        am33xx      nanobone:SD_BOOT

My nanobone.h file is attached.

I'd appreciate it is someone could tell me why env_nowhere.o is being compiled in even though
CONFIG_ENV_IS_NOWHERE is not defined.

Cheers
