Where is the variable (such as CONFIG_DM_MMC) of "xxxxxdefconfig file" defined in u-boot ？

CONFIG_OF_CONTROL=y
CONFIG_OF_EMBED=y
CONFIG_DEFAULT_DEVICE_TREE="stm32h743i-eval"
CONFIG_DM_MMC=y
CONFIG_STM32_SDMMC2=y

I can not find oud the variable on the left in u-boot project.

grep -GHrn 'config DM_MMC'

yields

drivers/mmc/Kconfig:26:config DM_MMC

So this is the Kconfig file where you find the definition.

https://www.kernel.org/doc/html/latest/kbuild/kconfig-language.html is a good start to learn about configuration variables.
