We'll need to update the defconfig in the build system. Currently if I
compile the kernel and generate a new defconfig (make savedefconfig),
I see the following changes in the 4.10 generated defconfig:

I know that CONFIG_ASPEED_FLASH_SPI is now CONFIG_SPI_ASPEED_SMC, but
I've yet to look at each of the other differences.
