The previous pcf2127 RTC chip could not read and set the correct time. When reading the data of internal registers, the read address was the value of register plus 1. This is because this chip requires the host to send a stop signal after setting the register address and before reading the register data.
This patch sets the flag that the stop signal is needed and fixes the bug of the original read and write time.

Can you modify this to use i2c_xfer() so that separate transactions are done?
I have sent the fourth edition you see the new patchwork: http://patchwork.ozlabs.org/project/uboot/list/?series=114242
