From 7e27f89fdfbe4acbaea2821073f90fa7e82b94ec Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Wed, 24 Oct 2012 07:28:16 +0000 Subject: [PATCH] README: Document CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG This option is intended to be set by boards which will set the board_name and board_rev environment variables. These are to be used when the U-Boot binary can support more than one board type at run-time and the user needs an easy way (for example for scripting to determine what device tree to load) to determine what board they are on.
