Changed subject as this is getting away from Joshua's original post
about the CryptoCape.

Are you guys talking about the crypto cape or the RTC cape? The
crypto capediscussed in this thread uses a ds3231 not a ds1307. Also
why anyone *needs* the rtc cape I don't get. just keep the rtc rail
powered on the processor. That I believe is a software issue.

From TI User guide on the TPS65217 [1] I find this.
TPS65217C is also targeted at the AM335x processor in the ZCZ package,
but the DCDC1 output voltage is set to 1.5 V to supply DDR3 memory.
*This version does not support AM335x RTC-only operation.*
Gerald has stated before that there *isn't* a battery backed RTC
available. Why would I even question this, faulty memory on my part
perhaps?
The question that still nags me is how does one set a sane time value
from a battery backed RTC as early as possible during bootup. Systemd
only supports setting the time from rtc0, no options to specify any
other device. Sillyness IMNSVHO...
I probably have already answered my own question, just use a shell
script ala init.d and be done with it.
