 Hello,

 Recently GPIO API is merged with the mainline. And Eventually I used the
 same for GPIO driver for BBB. And while testing it on hardware I did not
 able to get the Pin Input value correctly. So after debugging I found that
 it is the issue with the function return type. A brief for the same is
 given :-

 rtems_gpio_bsp_get_value() has return type of uint8_t. But as per API this
 function should return the bitmask. (DATAIN register & pinmask) . As BBB
 has pin no. 0 to 31 this should return 32 bits instead of 8.

 Herewith I am attaching a patch for that.

 Thanks.

 Regards,
 Ketul
