From 6895d4510a7758595b85b48a7f449bd61dfc812f Mon Sep 17 00:00:00 2001 From: John Rigby Date: Mon, 25 Jan 2010 23:12:58 -0700 Subject: Add support for KARO TX25 board This is an i.MX25 base board with only NAND so it uses nand_spl to boot. Signed-off-by: John Rigby Tune configuration, add support for (redundant) environment in NAND.
