use CAAM for none contiguous data

Hello,

I am trying to use CAAM on iMX6.

Using the provided SDK, I use QNX OS, and I managed to implement the component and use MD5 and SHA-x successfully, but only for data in a contiguous zone.

how to use the CAAM or descriptor commands to compute a hash (MD5, SHA-xxx) of a none contiguous data area?

Or, is there a descriptor command to compute a hash (MD5, SHA-xxx) on more than one data field in a single descriptor command?

 

The descriptor is as follows:

0xB0800007

0x8440000C

0x24540000

@Pointer to physical adress for data

data size

0x54200010

0x7C1C3EAC

 

Thanks

 

Khalid
