crypto: caam - Add new macros for building extended SEC descriptors (> 64 words)
added all supported math funtion on 8 byte boundary with immediate flag bit set automatically added MATH_SRC0_DPOVRD & MATH_SRC1_DPOVRD The function/defines above are needed for creating descriptors longer than 64 words Signed-off-by: Andrei Varvara <andrei.varvara@freescale.com> Reviewed-by: Phillips Kim-R1AAHA <Kim.Phillips@freescale.com> Reviewed-by: Fleming Andrew-AFLEMING <AFLEMING@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
