- add next2 init chip info logic - add next2 device id - Update logic of chip info functions to support next2 chip. Modify the functions to use formal "if defined()" macro instead of "ifdef". - Execute support-soc-tools property only on silicon platform - Separate OOT module_init symbol from postcore_init call on previos kernel.
