Sam reviewed v1, not sure enough changed to drop his review tag, anyway for me:
Acked-by: Andrew F. Davis afd@ti.com
Changes for v3:
- reword commit message, added avblib repository link, that stick to specific tag
- fix get_size_of_partition() function description.
Changes for v2:
- change the return code for the case when out_size_num_bytes is NULL (s/AVB_IO_RESULT_ERROR_IO/AVB_IO_RESULT_ERROR_INSUFFICIENT_SPACE/g)
