|

|

- Support for the GCC, LLVM and Arm Compiler 6 toolchains.
|
||||
|
||||
- Support for combining several libraries into a self-called "romlib" image
|

that may be shared across images to reduce memory footprint. The romlib image
|

is stored in ROM but is accessed through a jump-table that may be stored

shared across images to reduce memory footprint. The romlib image is stored
|
||||
in ROM but is accessed through a jump-table that may be stored
|
||||
in read-write memory, allowing for the library code to be patched.
|
||||
|
||||
- A prototype implementation of a Secure Partition Manager (SPM) that is based
|
||||
on the SPCI and SPRT specifications.
|
||||
|
||||
- Support for ARMv8.3 pointer authentication in the normal and secure worlds.
|
||||
The use of pointer authentication in the normal world is enabled whenever
|
||||
architectural support is available, without the need for additional build
|
||||
flags. Use of pointer authentication in the secure world remains an
|
||||
experimental configuration at this time and requires the ``ENABLE_PAUTH``
|
||||
build flag to be set.
|
||||
|
||||
- Position-Independent Executable (PIE) support. Initially for BL31 only, with
|
||||
further support to be added in a future release.

||||
