[U-Boot] [PATCH 3/3] crypto/fsl: add support for multiple SEC engines initialization

Alex Porosanu alexandru.porosanu at nxp.com
Fri Apr 29 14:18:00 CEST 2016


From: Alex Porosanu <alexandru.porosanu at freescale.com>

For SoCs that contain multiple SEC engines, each of them needs
to be initialized (by means of initializing among others the
random number generator).
