History
Gregory Nutt a76e137ce2 Squashed commit of the following: 
sched/init/nx_start.c:  Add support for CONFIG_BOARD_DRIVER_INITIALIZE.  If this option is selected then nx_start() will call a board-provided function board_driver_initialize() immediately after calling up_initialize().

    Rename CONFIG_BOARD_INITIALIZE to CONFIG_BOARD_LATE_INITIALIZE.

    Raname board_initialize() to board_late_initialize()
