| 17 | * A bloblist is a single contiguous chunk of memory with a header |
| 18 | * (struct bloblist_hdr) and a number of blobs in it. |
| 19 | * |
| 20 | * Each blob starts on a BLOBLIST_ALIGN boundary relative to the start of the |
| 21 | * bloblist and consists of a struct bloblist_rec, some padding to the required |
| 22 | * alignment for the blog and then the actual data. The padding ensures that the |
| 23 | * start address of the data in each blob is aligned as required. Note that |
| 24 | * each blob's *data* is aligned to BLOBLIST_ALIGN regardless of the alignment |
| 25 | * of the bloblist itself or the blob header. |
| 26 | * |
| 27 | * So far, only BLOBLIST_ALIGN alignment is supported. |
