[U-Boot] iMX6 - CONFIG_SYS_GENERIC_BOARD macro defined in U-Boot

[ansaris]

Hi,

We are using imx6Q SabreSD platform for our development with 
"U-Boot-2014.04".  But initially we used "U-Boot-2013.04" version.

We have gone through below file in U-Boot-2014.04 and found that the 
"CONFIG_SYS_GENERIC_BOARD" macro is defined.
~/u-boot-imx/include/configs/mx6sabre_common.h

Because of the macro "CONFIG_SYS_GENERIC_BOARD" definition, the 
"board_init_f" and "board_init_r" functions are executed from the below 
files respectively.
~/u-boot-imx/common/board_f.c
~/u-boot-imx/common/board_r.c

But we have gone through below file in U-Boot-2013.04 and found that the 
"CONFIG_SYS_GENERIC_BOARD" macro is not defined.
~/u-boot-imx/include/configs/mx6qsabre_common.h
With U-Boot-2013.04, the "board_init_f" and "board_init_r" functions are 
executed from the below file
~/u-boot-imx/arch/arm/lib/board.c

Please clarify our below doubt.
 From U-Boot-2014.04, why the "board_init_f" and "board_init_r" 
functions are not executed from below file.
~/u-boot-imx/arch/arm/lib/board.c

Please suggest us.

Thanks and Regards,
Ansari
