[U-Boot] [PATCH 0/7] Adds support for secure boot on Keystone SoCs (K2E)

[Madan Srinivas]

This series adds support for secure keystone family of devices, more
specifically for K2E (Edison).This work is similar to what has already
been done for the AM43xx and AM57xx SoCs and leverages much of the
infrastructure from them.

The big difference here is the ROM on keystone2 devices does not provide
any APIs for image authentication. Rather, the image authentication and
decryption routines and other security functions are provided by
software and can run on the ARM in Trustzone as well as on secure DSPs.

A component known as the boot monitor acts as they gateway to this secure
processing, and abstracts out the details from the public world. Unlike
OMAP class devices, where u-boot calls ROM APIs, u-boot calls into the boot-
monitor on keystone devices.

Other than this difference, most of the secure framework for AMxx and
DRAxx devices have been re-used.

Couple of other points to note :-

	-Support for SPL on secure keystone devices is still TBD,
	so boot from SPI flash, which needs SPL, is not supported currently
	on K2 devices.

	-A single image will work across all boot media for secure K2 devices.
