[EXTERNAL] [PATCH 00/10] Add AM62x LP SK support

[Nitin Yadav]

Hi Tom,

TI has one SDK release per SoC. If we go this way we will have to release
multiple SDK release for each board. It doesn't seem feasible to release
different SDK based on same SoC as we have other boards based on AM62x SoC
which we planning to add upstream support in future. In past, we followed
similar for jacinto platforms.

The Xilinx way you have mentioned won't work for TI as Xilinx has only one 
platform for upstream support.

I can evm.c changes to different files under board detection macro 
"CONFIG_TI_I2C_BOARD_DETECT" in different file to keep board code clean and
easy to follow.       

Regards,
Nitin
