From eee2fab0bddb2c460a96a943d7ed6b0f3718f0fd Mon Sep 17 00:00:00 2001 From: Piotr Wilczek Date: Wed, 22 Jan 2014 15:54:32 +0100 Subject: [PATCH] board:samsung:common: set envs with board unified information This patch sets envs that describe board information. The following envs are set: soc_id, soc_rev, board_rev. Based on this information, if CONFIG_OF_LIBFDT is enabled, the 'fdtfile' env is set as: fdtfile=${soc_family}${soc_id}-${board}.dtb The generated envs are intenionally not saved to persistent storage.
