      SPM: declare third cactus instance as UP SP · e96fc8e7
      Olivier Deprez authored
      
      
      The FF-A v1.0 spec allows two configurations for the number of EC/vCPU
      instantiated in a Secure Partition:
      -A MultiProcessor (MP) SP instantiates as many ECs as the number of PEs.
      An EC is pinned to a corresponding physical CPU.
      -An UniProcessor (UP) SP instantiates a single EC. The EC is migrated to
      the physical CPU from which the FF-A call is originating.
      This change permits exercising the latter case within the TF-A-tests
      framework.

      plat/arm: juno: Condition Juno entropy source with CRC instructions · eb18ce32
      Andre Przywara authored
      
      
      The Juno Trusted Entropy Source has a bias, which makes the generated
      raw numbers fail a FIPS 140-2 statistic test.
      
      To improve the quality of the numbers, we can use the CPU's CRC
      instructions, which do a decent job on conditioning the bits.
      
      This adds a *very* simple version of arm_acle.h, which is typically
      provided by the compiler, and contains the CRC instrinsics definitions
      we need. We need the original version by using -nostdinc.

      nxp: added the makefile helper macros · b749ae3d
      Pankaj Gupta authored
      
      
      NXP specifc macro SET_NXP_MAKE_FLAG is added.
      
      NXP has pool of multiple IPs. This macro helps:
      - In soc.mk, this macro help the selected IP source files to be included
        for that SoC.
        -- The set of IPs required for one NXP SoC is different to the set of IPs
           required by another NXP SoC.
      
      - For the same SoC,
        -- For one feature, the IP may be required in both BL2 and BL31.
        -- Without the above feature, that IP may be required in one.
           This macro help in selecting the inclusion of source and header files to:
           --- BL2 only
           --- BL31 only
           --- COMM (used by BL2 and BL31)

      plat/arm: juno: Refactor juno_getentropy() · 543f0d8b
      Andre Przywara authored
      
      
      Currently we use the Juno's TRNG hardware entropy source to initialise
      the stack canary. The current function allows to fill a buffer of any
      size, but we will actually only ever request 16 bytes, as this is what
      the hardware implements. Out of this, we only need at most 64 bits for
      the canary.
      
      In preparation for the introduction of the SMCCC TRNG interface, we
      can simplify this Juno specific interface by making it compatible with
      the generic one: We just deliver 64 bits of entropy on each call.
      This reduces the complexity of the code. As the raw entropy register
      readouts seem to be biased, it makes sense to do some conditioning
      inside the juno_getentropy() function already.
      Also initialise the TRNG hardware, if not already done.
