Hi Daniel,

For devices having LEDs or buttons connected via I2C or SPI connected
GPIO chips it is desireable to access these busses early during boot
in order to signal progress and failsafe-mode. Hence have support for
i2c-gpio and spi-gpio built-into the kernel on generic (ie. non-tiny)
systems.
For I2C two other configs should be also auto-selected:
+CONFIG_I2C=y
+CONFIG_I2C_ALGOBIT=y
+CONFIG_I2C_BOARDINFO=y
+CONFIG_I2C_GPIO=y
And in case of CONFIG_SPI_GPIO, it's already selected in top-level
target config:
https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/config-4.19#L216
https://github.com/openwrt/openwrt/blob/master/target/linux/ath79/config-4.14#L223
'make kernel_menuconfig CONFIG_TARGET=subtarget' will solve that.
