This patch introduces a new math test suite to the SBI unit tests. The changes include: * Updating lib/sbi/tests/objects.mk to include math_test_suite and sbi_math_test.o. * Adding a new file lib/sbi/tests/sbi_math_test.c which contains tests for log2roundup function using various cases. The addition of this test suite ensures that mathematical functions are verified and work as expected.
