This is what memalign(3) has
to say:
" The function posix_memalign() allocates size bytes and places the address of the allocated memory in *memptr. The address of the allo‐ cated memory will be a multiple of alignment, which must be a power of two and a multiple of sizeof(void *). If size is 0, then the value placed in *memptr is either NULL, or a unique pointer value that can later be successfully passed to free(3).
The obsolete function memalign() allocates size bytes and returns a pointer to the allocated memory. The memory address will be a mul‐ tiple of alignment, which must be a power of two. "
posix_memalign() does not exist in U-Boot, and it's not clear to me why memalign() should be considered obsolete. Is the difference just the ability to return -EINVAL?
The args are also totally different.
...in order to accommodate returning an error value.
... of course.
