This patch duplicates all those added lines for all current chips. Could 
we add a new config variable to share these; something like:

config TEGRA_ARMV7_COMMON
	select SUPPORT_SPL
	select SPL
	select OF_CONTROL
	select SPL_DISABLE_OF_CONTROL
	select CPU_V7
	select DM
	select DM_SPI_FLASH
	select DM_SERIAL
	select DM_I2C
	select DM_SPI
	select DM_GPIO

config TEGRA20
   	bool "Tegra20 family"
	select TEGRA_ARMv7_COMMON
