modified UBoot to include I2C communication
Dear Sir, I am working on a project based on NXP's iMX8M mini board, to include I2C library in the UBoot , I had browse thru UBoot website below, could anyone kindly advise which source file to amend and what are the code to include for I2C? like CONFIG_SYS_NUM_I2C_BUSES etc... is the modification to be done on Yocto project? Any help on source code or documentation are welcome, thanks.

U-Boot supports I2C, so long as your board has a devicetree with it enabled, etc. You can find examples that use this, e.g. firefly-rk3288
The 'SYS_NUM_I2C_BUSES' thing is not used for modern boards.
