Hi,

thanks for the advice, I have found the bad commit,
it is -> 02cc27c74f9b884b538bcd1b93342a4c05b5d608
sunxi: power: Change axp209 LDO3 and LDO4 default to disabled

after that I tried the v2016.01 release again, but changed
the two lines in config AXP_ALDO3_VOLT and config AXP_ALDO4_VOLT
back to their old values, now the SATA Port is working again.
