tqm8315 + ds1337: problems

[Pavel Machek <pavel@ucw.cz>]

Hi!

Something is wrong with real time clock on tqm8315 board... or maybe
with i2c on board, as I have trouble reading same information from
u-boot using "i2c md" commands:

Does rtc work for you on tqm8315? Any ideas how to debug this further?

Thanks,
								Pavel
