Please introduce defconfig for each board instead of this hackage .

Look at this example on how to use #include in defconfig files, it even 
supports multiple levels of config structure for deduplication purposes:

$  git grep include configs/imx*dh*
configs/imx6_dhcom_drc02_defconfig:#include <configs/dh_imx6.config>
configs/imx6_dhcom_pdk2_defconfig:#include <configs/dh_imx6.config>
configs/imx6_dhcom_picoitx_defconfig:#include <configs/dh_imx6.config>
configs/imx8mp_dhcom_drc02_defconfig:#include <configs/imx8mp_dhsom.config>
configs/imx8mp_dhcom_pdk2_defconfig:#include <configs/imx8mp_dhsom.config>
configs/imx8mp_dhcom_pdk3_defconfig:#include <configs/imx8mp_dhsom.config>
configs/imx8mp_dhcom_picoitx_defconfig:#include 
<configs/imx8mp_dhsom.config>
configs/imx8mp_dhsom.config:#include <configs/imx_dhsom.config>
configs/imx_dhsom.config:#include <configs/dhsom.config>
