- * CAAM hardware constructs a job descriptor which points to a shared descriptor
- * (as pointed by context_a of to-CAAM FQ).
- * When the job descriptor is executed by DECO, the whole job descriptor
- * together with shared descriptor gets loaded in DECO buffer, which is
- * 64 words (each 32-bit) long.
- *
- * The job descriptor constructed by CAAM hardware has the following layout:
- *
- * HEADER (1 word)
- * Shdesc ptr (1 or 2 words)
- * SEQ_OUT_PTR (1 word)
- * Out ptr (1 or 2 words)
- * Out length (1 word)
- * SEQ_IN_PTR (1 word)
- * In ptr (1 or 2 words)
- * In length (1 word)
- *
- * The shdesc ptr is used to fetch shared descriptor contents into DECO buffer.
- *
- * Apart from shdesc contents, the total number of words that get loaded in DECO
- * buffer are '8' or '11'. The remaining words in DECO buffer can be used for
- * storing shared descriptor.
