      rpi3: add RPI3_USE_UEFI_MAP build option · 4dcf1fad
      Pete Batard authored 
      

The default Raspberry Pi 3 memory mapping for ATF is geared towards
the use of uboot + Linux. This creates issues when trying to use
ATF with an UEFI payload and Windows on ARM64.

We therefore introduce new build option RPI3_USE_UEFI_MAP, that
enables the build process to use an alternate memory mapping that
is compatible with UEFI + Windows (as well as UEFI + Linux).

Fixes ARM-software/tf-issues#649

      SPM: Raise running priority of the core while in Secure Partition · 6e3bad36
      Sughosh Ganu authored 
      

The current secure partition design mandates that a) at a point, only
a single core can be executing in the secure partition, and b) a core
cannot be preempted by an interrupt while executing in secure
partition.

Ensure this by activating the SPM priority prior to entering the
parition. Deactivate the priority on return from the
partition.

      SPM: Register Secure Partition priority level with ehf module · 5681b292
      Sughosh Ganu authored 
      

Register a priority level, PLAT_SP_PRI, for secure partition with EL3
exception handling framework(ehf) module.

The secure partition manager(SPM) would raise the core's priority to
PLAT_SP_PRI before entering the secure partition, to protect the core
from getting interrupted while in secure partition.

      SPM: EHF: Build EHF module along with Secure Partition Manager · 8a3588a7
      Sughosh Ganu authored 
      

Add a dependency for building EL3 exception handling framework(EHF)
module with the secure partition manager(SPM).

The EHF module is needed for raising the core's running priority
before the core enters the secure partition, and lowering it
subsequently on exit from the secure partition.
