U-boot Header file selection for beaglebone board

When we do u-boot customization for beaglebone board (in any beaglebone board) how to select header file in include/configs/ outof so many variations present?

I found this many file
am335x_evm.h
am335x_igep0033.h
am335x_shc.h
am335x_sl50.h

Out of above files which one I should select for Beaglebone board(Black or Orange or Blue).

I know that AM335x 1GHz ARM® Cortex-A8 is used in beaglebone so out of this four any of this will be used.

am335x_evm, we then use the eeprom to enable difference between boards.
