tools/testing/scatterlist: Fix test to compile and run

2020-11-18T00:02:20+00:00

Add missing define of ALIGN_DOWN to make the test build and run. In addition, __sg_alloc_table_from_pages now support unaligned maximum segment, so adapt the test result accordingly.

tools/testing/scatterlist: Test new __sg_alloc_table_from_pages

2017-09-07T09:54:40+00:00

Exercise the new __sg_alloc_table_from_pages API (and through it also the old sg_alloc_table_from_pages), checking that the created table has the expected number of segments depending on the sequence of input pages and other conditions. v2: Move to data driven for readability. v3: Add some more testcases and -fsanitize=undefined.
