CONFIG_RTC is the "pc style" rtc driver, which works on a number of arches, so long as they have a rtc chip found in PCs, and it can be talked to as such. GEN_RTC is a generic RTC driver, which offers hooks to the architectures to do the hw-specific portions. This _could_ be made to work with RTCs over I2C, but at this time does not. PPC_RTC is like the above, except it calls the PPC hooks directly, and is obsolete (and gone in 2.6). -- Tom Rini http://gate.crashing.org/~trini/ ** Sent via the linuxppc-embedded mail list.
