* Patch by Rune Torgersen, 27 Feb 2004:
- Added LBA48 support (CONFIG_LBA48 & CFG_64BIT_LBA) - Added support for 64bit printing in vsprintf (CFG_64BIT_VSPRINTF) - Added support for 64bit strtoul (CFG_64BIT_STRTOUL) * Patch by Masami Komiya, 27 Feb 2004: Fix rarpboot: add autoload by NFS * Patch by Dan Eisenhut, 26 Feb 2004: fix flash_write return value in saveenv * Patch by Stephan Linz, 11 Dec 2003 expand config.mk to avoid trigraph warnings on NIOS * Rename "BMS2003" board into "HMI10"
