The Linux-for-Tegra kernel uses a very long command line.
The default value of CONFIG_SYS_CBSIZE is too small to printf out the long command line and causes a message like: bootarg overflow 602+0+0+1 > 512 on the console, and the board refuses to boot.
The default value of CONFIG_SYS_MAXARGS is too small to add a long long command line, and the kernel won't boot without the complete bootargs.
Increasing these two config options solves this problem.
