The MXS starts with CPSR V bit set, which makes the CPU jump to high vectors in case of an exception. Those high vectors are located at 0xffff0000, which is where the BootROM exception table is located as well. U-Boot should handle exceptions on its own using its own exception handling code, which is located at 0x0, i.e. at low vectors. Clear the CPSR V bit, so that the CPU would jump to low vectors on exception instead, and therefore run the U-Boot exception handling code.
