-Written by Thomas.Lange@corelatus.com 010805
-
-To make a system for gth that actually works ;-)
-the variable TBASE needs to be set to 0,1 or 2
-depending on location where image is supposed to
-be started from.
-E.g. make TBASE=1
-
-0: Start from RAM, base 0
-
-1: Start from flash_base + 0x10070
-
-2: Start from flash_base + 0x30070
-
-When using 1 or 2, the image is supposed to be launched
-from miniboot that boots the first U-Boot image found in
-flash.
-For miniboot code, description, see www.opensource.se
