ATOMIC_WORD

#define ATOMIC_WORD	(		val_if_64,
			val_if_32 )

Value:

        ((atomic_t)((sizeof(void *) == sizeof(uint64_t)) ? (val_if_64) : (val_if_32)))

Verify RISC-V specific atomic functionalities.

Test Objective:

• Test if the RISC-V atomic instructions API is correct.

Test Procedure:

• Call the API interface of the following atomic operations in turn, decision is based on function return value and target operands.
• atomic_swap()
• atomic_max()
• atomic_min()

Expected Test Result:

• The function return value and target operands are correct.

Pass/Fail Criteria:

• Successful if all check points in the test procedure have passed, failure otherwise.
