      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.

      xlat v2: Turn MMU parameters into 64-bit values · 6563c0be
      Antonio Nino Diaz authored 
      

Most registers are 64-bit wide, even in AArch32 mode:

- MAIR_ELx is equivalent to MAIR0 and MAIR1.
- TTBR is 64 bit in both AArch64 and AArch32.

The only difference is the TCR register, which is 32 bit in AArch32 and
in EL3 in AArch64. For consistency with the rest of ELs in AArch64, it
makes sense to also have it as a 64-bit value.

      xlat v2: Remove IMAGE_EL define · aa1d5f60
      Antonio Nino Diaz authored 
      

The Exception Level is now detected at runtime. This means that it is not
needed to hardcode the EL used by each image.

This doesn't result in a substantial increase of the image size because
the initialization functions that aren't used are garbage-collected by
the linker.

In AArch32 the current EL has been changed from EL3 to EL1 because the
the AArch32 PL1&0 translation regime behaves more like the AArch64 EL1&0
translation regime than the EL3 one.

      Run compiler on debug macros for type checking · cf24229e
      Sandrine Bailleux authored 
      

Even if the log output is too low for a message to be printed out on
the console by the debug macros, it should still be evaluated by the
compiler to get some type checking and validation of the format
specifiers. To do so, introduce the no_tf_log() macro that encloses
the call to tf_log() in an always-false condition.

This avoids the problem of discovering build issues only when we build
the firmware with the right LOG_LEVEL value.

      ARM platforms: Make arm_lock static · 1931d1d7
      Sandrine Bailleux authored 
      

The ARM_INSTANTIATE_LOCK macro defines a lock meant to be further
manipulated using the arm_lock_init/get/release() macros. It has 2
variants, depending on the BL image it is compiled for. One version
defines the lock variable with internal linkage whereas the other one,
with external linkage.

Code that uses these macros is not compliant with MISRA rule 8.4 because
when using the external linkage version, there is no visible declaration
for the lock variable.

This patch defines the arm_lock variable with internal linkage in both
cases. This fits well the way these macros are used in the code today,
where the lock is not used outside of the translation unit it is
defined in.
