Where is the code for SPL DDR setup?

I know that I need to modify/customize the SPL logic for DDR setup. My custom board uses different DDR hardware than the EVK. But... where is the SPL DDR setup code? How does one find code in a Yocto build tree? I count over 12 million files!

I did find a dir called spl at: build/tmp/work/imx8mn_lpddr4_evk-poky-linux/u-boot-imx/2024.04/git/common/spl. Looks promising, but how do I know it's the right code? And I still don't know what file is for DDR setup
