From 5911c0924f403561d8f1f2f437fd9a6efc5ad82a Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Fri, 15 Jul 2016 07:14:25 -0700 Subject: imx: ventana: make hwconfig initialize based on board configuration The hwconfig env var allows user to control hardware specific configuration of board specific features but not all Ventana boards have the same features. We will use the magic default value of "_UNKNOWN_" to signify that the bootloader should create this based on detected board model.
