Since we need to reconfigure Reset time for OMAP4, we found the OMAP4 register definition for reset time is wrong according to spec of OMAP4. And we verified this by reading default value of register. We found the offset definition of Reset time and Reset Test register should be switched. After correcting this bug, we verified by changing the value of reset time register, the pulse generated for reset is also changed as expected on scope.
