[U-Boot] I can not read Linux image from my nand flash

[Peter Pan]

I defined the CONFIG_SYS_64BIT_VSPRINTF, and change the __kernel__loff_t back
to long long, and it works.

My platform is a MPC8247 based customized board, which designed by my
colleagues.
 Nand is Samsung K9K8G08U0M.

Thank you very much for your advice. Now my u-boot works fine now.
