      AArch64: Enable MPAM for lower ELs · 5f835918
      Jeenu Viswambharan authored 
      

Memory Partitioning And Monitoring is an Armv8.4 feature that enables
various memory system components and resources to define partitions.
Software running at various ELs can then assign themselves to the
desired partition to control their performance aspects.

With this patch, when ENABLE_MPAM_FOR_LOWER_ELS is set to 1, EL3 allows
lower ELs to access their own MPAM registers without trapping to EL3.
This patch however doesn't make use of partitioning in EL3; platform
initialisation code should configure and use partitions in EL3 if
required.

      Add support for romlib in the build system · 5accce5b
      Roberto Vargas authored 
      

Romlib is a new image that is stored in ROM and contains the code of
several libraries that can be shared between different images. All
the functions within in the library are accessed using a jump table
which allows to update the romlib image whithout changing the binary
compatibility. This jump table can be also stored in RAM and it can
allow to patch a romlib with potential bugs fixes..

      Create a library file for libc · 61f72a34
      Roberto Vargas authored 
      

TF Makefile was linking all the objects files generated for the
c library instead of creating a static library that could be
used in the linking stage.

      ARM platforms: Allow board specific definition of SP stack base · 2e4a509d
      Sughosh Ganu authored 
      

The SGI platforms need to allocate memory for CPER buffers. These
platform buffers would be placed between the shared reserved memory
and the per cpu stack memory, thus the need to redefine stack base
pointer for these platforms. This patch allows each board in ARM
platform to define the PLAT_SP_IMAGE_STACK_BASE.

      SGI: Include arm_spm_def.h in platform_def.h · d9cc9372
      Sughosh Ganu authored 
      

Include arm_spm_def.h in the platform_def.h file. Without this
inclusion, we get build errors like

In file included from services/std_svc/spm/sp_setup.c:12:0:
services/std_svc/spm/sp_setup.c: In function 'spm_sp_setup':
services/std_svc/spm/sp_setup.c:61:57: error: 'PLAT_SPM_BUF_BASE'
  undeclared (first use in this function)
  write_ctx_reg(get_gpregs_ctx(ctx), CTX_GPREG_X0, PLAT_SPM_BUF_BASE);

Now that the platform_def.h includes arm_spm_def.h, remove inclusion
of platform_def.h in arm_spm_def.h to remove the circular dependency.

      RAS: Introduce handler for Uncontainable errors · b56dc2a9
      Jeenu Viswambharan authored 
      

Uncontainable errors are the most severe form of errors, which typically
mean that the system state can't be trusted any more. This further means
that normal error recovery process can't be followed, and an orderly
shutdown of the system is often desirable.

This patch allows for the platform to define a handler for Uncontainable
errors received. Due to the nature of Uncontainable error, the handler
is expected to initiate an orderly shutdown of the system, and therefore
is not expected to return. A default implementation is added which falls
back to platform unhandled exception.

Also fix ras_arch.h header guards.
