Hi,
I am adding U-boot support for custom board which is based on AM335x. When I am trying to compile u-boot sources I get following errors:

Above functions are defined in board/ti/common/ and I am including board_detect.h in my board.c file. I am creating my custom board here -> board/SYS_VENDOR/SYS_BOARD.
I added following in arch/arm/mach-omap2/am33xx/Kconfig to define new target which has TI_I2C_BOARD_DETECT also. And done all the necessary steps.
+config TARGET_AM335X_EST4
+ bool "Support am335x_est4"
+ select BOARD_LATE_INIT
+ select DM
+ select DM_GPIO
+ select DM_SERIAL
+ select TI_I2C_BOARD_DETECT
Question: Can I not use board detect logic defined in board/ti/common if my is custom board is not present in board/ti folder?
IMP NOTE: If I move my custom board files under board/ti then I do not observe above errors.
Regards,
Raxesh
