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()

|
*
|
|
* Description:
|
|
* All TMS570 architectures must provide the following entry point. This
|
|
* function is called near the beginning of _start. This function is
|
|
* called after clocking has been configured but before caches have been
|
|
* enabled and before any devices have been initialized. .data/.bss
|
|
* memory may or may not have been initialized (see the "special
|
|
* precautions" below).
|
|
*
|
|
* This function must perform low level initialization including
|
|
*
|
|
* - Initialization of board-specific memory resources (e.g., SDRAM)
|
|
* - Configuration of board specific resources (GPIOs, LEDs, etc).
|
|
* - Setup of the console UART. This UART done early so that the serial
|
|
* console is available for debugging very early in the boot sequence.
|
|
*
|
|
* Special precautions must be taken if .data/.bss lie in SRAM. in that
|
|
* case, the boot logic cannot initialize .data or .bss. The function
|
|
* must then:
|
|
*
|
|
* - Take precautions to assume that logic does not access any global
|
|
* data that might lie in SDRAM.
|
|
* - Call the function arm_data_initialize() as soon as SDRAM has been
|
|
* properly configured for use.
