Just for completeness, I'm going to mention again that I think this
should just return TEGRA_SOC_T30 all the time. Sorry if that's
belaboring the point!
I just noticed your recent email saying you got 408MHz working, so I
guess my comment is moot anyway:-)

This is fine, but the following wouldn't require editing again for
future chips:
puts(CONFIG_SYS_SOC);
puts("\n");
(although it ends up being all lower-case; perhaps there's some other
variable that is upper-case?)
