OK, I saw "env_*" stuff in the "ifndef CONFIG_SPL_BUILD" section, but  
later some of it shows up in "ifdef CONFIG_SPL_BUILD" as well.

So, do you want a v2, or is it OK because it's not interactive?  In the  
latter case should env_callback.o be removed from the SPL build?

Also, env_nvedit.o, env_common.o, and env_flash.o are included for SPL  
regardless of CONFIG_SPL_NET_SUPPORT.  In fact it looks like  
env_nvedit.o will be included twice if CONFIG_SPL_NET_SUPPORT is  
enabled. :-P
