      Fix build for SEPARATE_CODE_AND_RODATA=0 · 2ecaafd2
      Daniel Boulby authored 
      

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

      RAS: SGI: Add flags needed to build components for RAS feature · f29d1828
      Sughosh Ganu authored 
      

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.

      SPM: SGI: Map memory allocated for secure partitions · d9523919
      Sughosh Ganu authored 
      

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.

      Include board_arm_def.h through the platform's header · 46b69e3d
      Sughosh Ganu authored 
      

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.

      ARM Platforms: Update CNTFRQ register in CNTCTLBase frame · 342d6220
      Soby Mathew authored 
      

Currently TF-A doesn't initialise CNTFRQ register in CNTCTLBase
frame of the system timer. ARM ARM states that "The instance of
the register in the CNTCTLBase frame must be programmed with this
value as part of system initialization."

The psci_arch_setup() updates the CNTFRQ system register but
according to the ARM ARM, this instance of the register is
independent of the memory mapped instance. This is only an issue
for Normal world software which relies on the memory mapped
instance rather than the system register one.

This patch resolves the issue for ARM platforms.

The patch also solves a related issue on Juno, wherein
CNTBaseN.CNTFRQ can be written and does not reflect the value of
the register in CNTCTLBase frame. Hence this patch additionally
updates CNTFRQ register in the Non Secure frame of the CNTBaseN.

Fixes ARM-Software/tf-issues#593

      plat/arm: Migrate AArch64 port to the multi console driver · 88a0523e
      Antonio Nino Diaz authored 
      

The old API is deprecated and will eventually be removed.

Arm platforms now use the multi console driver for boot and runtime
consoles. However, the crash console uses the direct console API because
it doesn't need any memory access to work. This makes it more robust
during crashes.

The AArch32 port of the Trusted Firmware doesn't support this new API
yet, so it is only enabled in AArch64 builds. Because of this, the
common code must maintain compatibility with both systems. SP_MIN
doesn't have to be updated because it's only used in AArch32 builds.
The TSP is only used in AArch64, so it only needs to support the new
API without keeping support for the old one.

Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
causes the UARTs to reset (except for the one used by the TSP). This
means that they must be unregistered when suspending and re-registered
when resuming. This wasn't a problem with the old driver because it just
restarted the UART, and there were no problems associated with
registering and unregistering consoles.

The size reserved for BL2 has been increased.

      Make TF UUID RFC 4122 compliant · 03364865
      Roberto Vargas authored 
      

RFC4122 defines that fields are stored in network order (big endian),
but TF-A stores them in machine order (little endian by default in TF-A).
We cannot change the future UUIDs that are already generated, but we can store
all the bytes using arrays and modify fiptool to generate the UUIDs with
the correct byte order.
