* powerpc/mpc85xx: SECURE BOOT- Enable chain of trust in SPLSumit Garg2016-07-21-0/+8
| | | | | | | | | | | | | | | | As part of Chain of Trust for Secure boot, the SPL U-Boot will validate the next level U-boot image. Add a new function spl_validate_uboot to perform the validation. Enable hardware crypto operations in SPL using SEC block. In case of Secure Boot, PAMU is not bypassed. For allowing SEC block access to CPC configured as SRAM, configure PAMU.

* powerpc/SECURE_BOOT: Add PAMU driverAneesh Bansal2016-02-24-0/+433
PAMU driver basic support for usage in Secure Boot. In secure boot PAMU is not in bypass mode. Hence to use any peripheral (SEC Job ring in our case), PAMU has to be configured. The patch reverts commit 7cad2e38d61e27ea59fb7944f7e647e97ef292d3. The Header file pamu.h and few functions in driver have been derived from Freescale Libos.
