Hello. I was trying to add custom vendor and board based on 8370 and I found that it is not easy as should be. The problem is that MT is not using CONFIG_SOC to distinguish between SOCs but it is using CONFIG_TARGET_8370=y where role of CONFIG_TARGET_x is completely different. So I cannot define my own CONFIG_TARGET_MY_GENIO_BOARD because all .c files needed for 8370 will not be built when CONFIG_TARGET_8370 is not enabled.
