/**
* Test specification for: test_memcpy_memcmp
*
* Description: Test functionality of the utility functions nvgpu_memcpy and
* nvgpu_memcmp.
*
* Test Type: Feature, Error guessing, Boundary values
*
* Targets: nvgpu_memcpy, nvgpu_memcmp
*
* Input: None.
*
* Steps:
* - Initialize source array to the values 1-10.
* - Initialize destination array to all 0's.
* - Call nvgpu_memcpy with the source & destination arrays, passing the full
* length.
* - Call nvgpu_memcmp with the source & destination arrays, passing the full
* length. Verify it returns a match.
* - Re-init destination to 0.
* - Call nvgpu_memcpy with the source & destination arrays, passing length-1.
* - Call nvgpu_memcmp with the source & destination arrays, passing length-1.
* Verify it returns a match.
* - Verify the final element of the destination array is still 0.
* - Call nvgpu_memcmp with the source & destination arrays, passing length.
* Verify it returns a non-match.
* - Call nvgpu_memcmp with a length 0. Verify a match is returned.
*
* Output: Returns PASS if expected result is met, FAIL otherwise.

* - Call nvgpu_strnadd_u32 with an insufficient string size for the requested.
* number. Verify 0 is returned.
* - Call nvgpu_strnadd_u32 with a decimal value of 1000. Verify returned size
* is 4 and the string contains "1000".
* - Call nvgpu_strnadd_u32 with a hexidecimal value of 0xdeadbeef. Verify
* returned size is 8 and the string contains "deadbeef".
