mx6q: mx6qsabrelite: Conditionally define macros for environment in serial flash
The default settings store the persistent environment on SD card and not serial flash (SPI NOR). To use SPI NOR to save the environment instead of SD card, edit include/configs/mx6qsabrelite.h and - undefine CONFIG_ENV_IS_IN_MMC - define CONFIG_ENV_IS_IN_SPI_FLASH The SPI driver can take as chip select the controller's chip selects as well as an external GPIO. The LSB byte has the value of the internal chip select, the highest (thought as 16-bit value) contains the GPIO number. The GPIO used on Sabre Lite is GP3:19 == 83.
