The sdio bus power should be disable by clear RSI_PWR_CONTROL register POWER ON

bits, but it still has 3.3V(VDD3SD) on sdio bus, the RSI power can't be cut off.

--- Mike Frysinger 2010-11-09 05:49:05

this has been pushed to processor support by Steven now ... waiting for them

--- steven miao 2010-11-10 03:15:47

According to the bf518 ebrd's schematics the VDD 3.3V for sdio connects to power

directly and can't be cut off. So the sdio wifi module can't not be reset with

VDD 3.3V on. As the sdio wifi testing is ok, maybe we can ignore this issue.
