From: Stefan Agner stefan.agner@toradex.com
This commit adds support for the Toradex Colibri iMX7D 1GB Computer on Module. The module is very similar to the Colibri iMX7D 512MB but uses eMMC instead of raw NAND. This patch introduces a new board specific Kconfig symbol to select between the two flash options.
