* Test specification for: test_bitops_misc
*
* Description: Test the various macros implemented in bitops unit.
*
* Test Type: Feature
*
* Targets: BITS_TO_LONGS, BIT, GENMASK, for_each_set_bit
*
* Input: None
*
* Steps:
* - Invoke BITS_TO_LONGS for various bit values and confirm the return value
* is as expected.
* - Invoke GENMASK for various mask value settings. Confirm if the return
* value has only the requested bits set.
* - Invoke for_each_set_bit for a particular bit pattern. Confirm if the loop
* is executed only for set bit positions.
* - Invoke BIT macro for various bit positions in loop. Confirm if the bit
* positions are as requested.
*
* Output: Returns SUCCESS if all the macro invocations returns result as
* expected. Otherwise, the test returns FAIL.
