TWL4030 Add power reset button
The Zoom2 power reset button is on the top right side of the main board. Press and hold for about to 8 seconds to completely reset the board. Some of the beta boards have a hardware problem that prevents using this feature. If is difficult to further characterize the boards that fail. So disable resetting for all beta boards. The Zoom1 reset button is the red circle on the top right, front of the board. Press and hold the button for 8 seconds to completely reset the board. After analyzing beagle, it was determined that other boards that use the twl4030 for power managment can also make use this function. The resetting is done by the power management part of the twl4030. Since there is no existing drivers/power, add one. The compilation of power/twl4030.h is controlled by the config variable CONFIG_TWL4030_POWER Signed-off-by: Tom Rix <Tom.Rix@windriver.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Heiko Schocher <hs@denx.de>
