      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.

      plat/marvell: fix SPD handling in dram port · 1e179c79
      Konstantin Porotchkin authored 
      

The DRAM port code issues a dummy write to SPD page-0 i2c address
in order to select this page for the forthcoming read transaction.
If the write buffer length supplied to i2c_write is not zero, this
call is translated to 2 bus transations:

- set the target offset
- write the data to the target

However no actual data should be transferred to SPD page-0 in order
to select it. Actually, the second transation never receives an ACK
from the target device, which caused the following error report:

ERROR:   Status 30 in write transaction

This patch sets the buffer length in page-0 select writes to zero,
leading to bypass the data transfer to the target device.
Issuing the target offset command to SPD page-0 address effectively
selects this page for the read operation.
