iMX6 - CONFIG_SYS_GENERIC_BOARD macro defined in U-Boot

Hi,

We are using imx6Q SabreSD platform for our development with 
Linux3.14.28_1.0.0-GA BSP.
But initially we used Linux 3.10.17_1.0.0-GA BSP.

The Linux3.14.28_1.0.0-GA BSP uses "U-Boot-2014.04" and the Linux 
3.10.17_1.0.0-GA BSP uses "U-Boot-2013.04" versions.

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


 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

Maybe it would be better if you send this question to u-boot mailing list.

I don't know the answer, but if it was a quiz, I would guess it is
because of SPL.
