      Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__ · d5dfdeb6
      Julius Werner authored 
      

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

      Tegra: dummy support for the io_storage backend · 8d56e24b
      Varun Wadekar authored 
      

This patch provides dummy macros and platform files to compile
the io_storage driver backend. This patch is necessary to
remove the "--unresolved=el3_panic" linker flag from Tegra's
makefiles and allow us to revert this workaround, previously
suggested by the ARM toolchain team.

The "--unresolved=el3_panic" flag actually was a big hammer that
allowed Tegra platforms to work with armlink previously but it
masks legit errors with the code as well.

      Tegra: Support for scatterfile for the BL31 image · c2ad38ce
      Varun Wadekar authored 
      

This patch provides support for using the scatterfile format as
the linker script with the 'armlink' linker for Tegra platforms.

In order to enable the scatterfile usage the following changes
have been made:

* provide mapping for ld.S symbols in bl_common.h
* include bl_common.h from all the affected files
* update the makefile rules to use the scatterfile and armlink
  to compile BL31
* update pubsub.h to add sections to the scatterfile

NOTE: THIS CHANGE HAS BEEN VERIFIED WITH TEGRA PLATFORMS ONLY.

      Tegra: restrict non-secure PMC accesses · a01b0f16
      Varun Wadekar authored 
      

Platforms that do not support bpmp firmware, do not need access
to the PMC block from outside of the CPU complex. The agents
running on the CPU can always access the PMC through the EL3
exception space.

This patch restricts non-secure world access to the PMC block on
such platforms.

      Tegra186: memctrl: disable stream id writes for MC clients · a7f4e89b
      Krishna Reddy authored 
      

As per the latest recommendations from the hardware team, write access
needs to be disabled for APE, BPMP, NvDec and SCE clients. This patch
disables stream id register writes for these MC clients to implement
those recommendations.

      Tegra: bpmp: mark device "not present" on boot timeout · e6712cf5
      Varun Wadekar authored 
      

This patch updates the state machine to "not present" if the bpmp
firmware is not found in the system during boot. The suspend
handler also checks now if the interface exists, before updating
the internal state machine.
