Change max size of uncompressed uImage's to 8MByte and add
CFG_BOOTM_LEN to adjust this setting. As mentioned by Robin Getz on 2005-05-24 the size of uncompressed uImages was restricted to 4MBytes. This default size is now increased to 8Mbytes and can be overrided by setting CFG_BOOTM_LEN in the board config file. Patch by Stefan Roese, 13 Mar 2006
