Subject: [U-Boot-Users] [PATCH v3] 83xx: fix CFG_ENV_ADDR and CFG_ENV_SECT_SIZE definitions
Date: Mon,  5 Nov 2007 09:34:06 -0600	[thread overview]
Message-ID: <1194276846902-git-send-email-timur@freescale.com> (raw)

Fix the definitions of CFG_ENV_ADDR and CFG_ENV_SECT_SIZE for all of the
currently-defined 83xx boards.  This change guarantees that the environment
will be located on the first flash sector after the U-Boot image.
