I find the ARM support in drivers/char/nvram to be surprising, not to say questionable. The /proc/driver/nvram implementation, given defined(__arm__), decodes the NVRAM contents in exactly the same format as when defined(__i386__) || defined(__x86_64__).
That's because it's used on the Netwinder and EBSA285 platforms, which are PCI-like, complete with a southbridge which makes them look like a PC.
Whereas, only MIPS and PowerPC defconfigs set CONFIG_RTC_DRV_CMOS at all, and without that symbol the driver will never be built for ARM. This raises the question, does /proc/driver/nvram do anything useful on any ARM platforms?
