I've added summary of used optimization method: =95 Reduction of kernel and filesystem size =95 Kernel features: naked boot, initrd without compression =95 Optimization of NAND flash interface in boot loader =95 Boot time was measured with utility tstamp =95 You can find more detailed list of methods at http://elinux.org/Boo= t_Time =95 Techniques for improving embedded Linux startup time, presentation: http://www.makelinux.com/emb/fastboot/MontaVista Actually, detailed implementations of optimization methods are described in numerous documents.
