I checked the configs for all the davinci boards, and cam_enc_4xx,
da850* and hawkboard use spl. Out of these the da850* use a spi
flash, while cam_enc_4xx and hawkboard both use a nand. So we should
not be using the CONFIG_SPL_SPI_LOAD check to exclude the gdata and
bdata objects -- these are now needed after adding the libcommon
support to the hawkboard.
Also, the cam_enc_4xx board which uses a spl does not have
CONFIG_SPL_LIBCOMMON_SUPPORT and CONFIG_SPL_LIBGENERIC_SUPPORT
defined and this patchset does not add these defines for the
board. Was adding these defines for the board missed out. If so,
then this patch would no longer be needed.
