Arnd,

I think the "ifdef" should be removed here because we had a runtime
Tegra SoC detection code here, the "ifdef" here would cause the code
won't be built for the tegra_defconfig that we are using. And a typo
need to fix here, it should be "cpu_to_csr_reg" not "cpu_to_csr_req".
Sorry.

Thanks for report. Will provide a fix.
