Yes, it's intentional. At the moment OMAP spl doesn't need anything
from this directory other than the eabi_comapt.o. In the future if
somebody needs contents from another file for SPL they may have to
bring it out of the '#ifndef CONFIG_SPL_BUILD' block.
In all likelihood board.c will always remain out of SPL because board.c
defines board_init_f() and board_init_r() that are re-defined for SPL.
In the event some SPL has to reuse some content from this file, we may
have to make these functions weakly linked in this file. But I don't
think that will be ever needed.
best regards,
Aneesh
