[PATCHv3 0/4] SCP03 control

[Jorge Ramirez-Ortiz]

The following patchset allows U-Boot to enable the Secure Channel
Protocol 03 implemented in a TEE and executed between the processor
and the secure element.

It also allows U-Boot to request the rotation of the encryption keys
defined as part of the protocol; when this is request is made, the TEE
will derive new keys program them in the secure element so all
communications with the secure element remains secured.

Changes v3:
  common: SCP03 control (enable and provision of keys)
  Simon Glass: document Kconfig
  	       include common.h
	       return -ENXIO on TA not available
	       
  cmd: SCP03: enable and provision command
  Simon Glass: requested .rst docs
               printf on error
	       use U_BOOT_CMD_WITH_SUBCMDS

  drivers: tee: sandbox: SCP03 control emulator	       
  Simon Glass: expand Kconfig information

Changes v2:
  remove obsolete patch (wasnt part of the set)
