      juno: Revert FWU update detect mechanism · 4da6f6cd
      Sathees Balya authored 
      The patch 7b56928a

 unified the FWU mechanism on FVP and Juno
platforms due to issues with MCC firmware not preserving the
NVFLAGS. With MCCv150 firmware, this issue is resolved. Also
writing to the NOR flash while executing from the same flash
in Bypass mode had some stability issues. Hence, since the
MCC firmware issue is resolved, this patch reverts to the
NVFLAGS mechanism to detect FWU. Also, with the introduction
of SDS (Shared Data Structure) by the SCP, the reset syndrome
needs to queried from the appropriate SDS field.

      ARM Platforms:Enable non-secure access to UART1 · 2431d00f
      Alexei Fedorov authored 
      

Adds an undocumented build option that enables non-secure access to
the PL011 UART1.
This allows a custom build where the UART can be used as a serial debug
port for WinDbg (or other debugger) connection.

This option is not documented in the user guide, as it is provided as a
convenience for Windows debugging, and not intended for general use.
In particular, enabling non-secure access to the UART might allow
a denial of service attack!

      Add cache flush after BL1 writes heap info to DTB · 63cc2658
      John Tsichritzis authored 
      

A cache flush is added in BL1, in Mbed TLS shared heap code. Thus, we
ensure that the heap info written to the DTB always gets written back to
memory.  Hence, sharing this info with other images is guaranteed.

      Additional runtime check for DTB presence in BL2 · a606031e
      John Tsichritzis authored 
      

In Mbed TLS shared heap code, an additional sanity check is introduced
in BL2. Currently, when BL2 shares heap with BL1, it expects the heap
info to be found in the DTB. If for any reason the DTB is missing, BL2
cannot have the heap address and, hence, Mbed TLS cannot proceed. So,
BL2 cannot continue executing and it will eventually crash.  With this
change we ensure that if the DTB is missing BL2 will panic() instead of
having an unpredictable crash.

      Slight improvements in Mbed TLS shared heap helpers · 7af2dd2e
      John Tsichritzis authored 
      

This patch, firstly, makes the error messages consistent to how printed
strings are usually formatted. Secondly, it removes an unnecessary #if
directive.

      Fix build for SEPARATE_CODE_AND_RODATA=0 · 2ecaafd2

TF won't build since no memory region is specified
for when SEPARATE_CODE_AND_RODATA=0 it still relies on
the ARM_MAP_BL_RO_DATA region which is never defined for
this case. Create memory region combining code and RO data for
when the build flag SEPARATE_CODE_AND_RODATA=0 to fix this

Add the various flags that are required to build the components needed
to enable the RAS feature on SGI575 platform. By default, all flags
are set to 0, disabling building of all corresponding components.

      RAS: SGI: Add platform handler for RAS interrupts · 485fc954
      Sughosh Ganu authored 
      

Add a platform specific handler for RAS interrupts and configure the
platform RAS interrupts for EL3 handling. The interrupt handler passes
control to StandaloneMM code executing in S-EL0, which populates the
CPER buffer with relevant error information. The handler subsequently
invokes the SDEI client which processes the information in the error
information in the CPER buffer. The helper functions
plat_sgi_get_ras_ev_map and plat_sgi_get_ras_ev_map_size would be
defined for sgi platforms in the subsequent patch, which adds sgi575
specific RAS changes.

The secure partition manager reserves chunks of memory which are used
for the S-EL0 StandaloneMM image and the buffers required for
communication between the Non-Secure world with the StandaloneMM
image. Add the memory chunks to relevant arrays for mapping the
regions of memory with corresponding attributes.

      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.

The board_arm_def.h header file needs to be included via the platform
definition header. Not doing so, results in a redefinition error of
PLAT_ARM_MAX_BL31_SIZE macro, if defined in the platform definition
file.
