Dear Dat Tran,

Also running the latest X-Loader 1.50 and U-Boot 2011.09-rc1, it takes about 2 seconds from power on to starting the Linux Kernel. My Kernel takes 1 second to load and my file system takes another 1.5 seconds for a total of 4.5 seconds from power on to the login prompt on serial. I assume the U-Boot-SPL will only speed up the first half of my boot time. If so, how much of a difference do you think I will see with this patch.
It may speed up more than just the first half, because, if done right, you will have the caches enabled in the new setup, which may speed up NAND loading by a factor of 10 or more...
Best regards,
Wolfgang Denk
