      Tegra: sanity check NS address and size before use · 685e5609
      Varun Wadekar authored 
      

This patch updates the 'bl31_check_ns_address()' helper function to
check that the memory address and size passed by the NS world are not
zero.

The helper fucntion also returns the error code as soon as it detects
inconsistencies, to avoid multiple error paths from kicking in for the
same input parameters.

      Tegra: memctrl_v2: fixup sequence to resize video memory · a7749acc
      Varun Wadekar authored 
      

The previous sequence used by the driver to program the new memory
aperture settings and clear the non-overlapping memory was faulty.
The sequence locked the non-overlapping regions twice, leading to
faults when trying to clear it.

This patch modifies the sequence to follow these steps:

* move the previous memory region to a new firewall register
* program the new memory aperture settings
* clean the non-overlapping memory

This patch also maps the non-overlapping memory as Device memory to
follow guidance from the arch. team.

      plat/arm: Fix load address of TB_FW_CONFIG · 15865870
      Manish V Badarkhe authored 
      

Load address of tb_fw_config is incorrectly mentioned
in below device trees:
1. rdn1edge_fw_config.dts
2. tc0_fw_config.dts

Till now, tb_fw_config load-address is not being retrieved from
device tree and hence never exeprienced any issue for tc0 and
rdn1edge platform.

For tc0 and rdn1edge platform, Load-address of tb_fw_config should
be the SRAM base address + 0x300 (size of fw_config device tree)
Hence updated these platform's fw_config.dts accordingly to reflect
this load address change.

      rockchip: rk3368: fix PLAT_RK_CLST_TO_CPUID_SHIFT · 198a705f
      Philipp Tomsich authored 
      

The RK3368 has two clusters of 4 cores and it's cluster id starts at
bit 8 of the MPIDR.  To convert from the cluster id (0 or 1) to the
lowest CPU-ID in the respective cluster, we thus need to shift by 6
(i.e. shift by 8 to extract the cluster-id and multiply by 4).

This change is required to ensure the PSCI support can index the
per-cpu entry-address array correctly.

      plat/fvp: Add support for dynamic description of secure interrupts · 452d5e5e
      Madhukar Pappireddy authored 
      

Using the fconf framework, the Group 0 and Group 1 secure interrupt
descriptors are moved to device tree and retrieved in runtime. This
feature is enabled by the build flag SEC_INT_DESC_IN_FCONF.

      GICv3: GIC-600: Detect GIC-600 at runtime · b4ad365a
      Andre Przywara authored 
      

The only difference between GIC-500 and GIC-600 relevant to TF-A is the
differing power management sequence.
A certain GIC implementation is detectable at runtime, for instance by
checking the IIDR register. Let's add that test before initiating the
GIC-600 specific sequence, so the code can be used on both GIC-600 and
GIC-500 chips alike, without deciding on a GIC chip at compile time.

This means that the GIC-500 "driver" is now redundant. To allow minimal
platform support, add a switch to disable GIC-600 support.

      dualroot: add chain of trust for secure partitions · 44f1aa8e
      Manish Pandey authored 
      

A new certificate "sip-sp-cert" has been added for Silicon Provider(SiP)
owned Secure Partitions(SP). A similar support for Platform owned SP can
be added in future. The certificate is also protected against anti-
rollback using the trusted Non-Volatile counter.

To avoid deviating from TBBR spec, support for SP CoT is only provided
in dualroot.
Secure Partition content certificate is assigned image ID 31 and SP
images follows after it.

The CoT for secure partition look like below.

      xlat_tables_v2: add base table section name parameter for spm_mm · 0922e481
      Masahisa Kojima authored 
      Core spm_mm code expects the translation tables are located in the
inner & outer WBWA & shareable memory.
REGISTER_XLAT_CONTEXT2 macro is used to specify the translation
table section in spm_mm.

In the commit 363830df

 (xlat_tables_v2: merge
REGISTER_XLAT_CONTEXT_{FULL_SPEC,RO_BASE_TABLE}), REGISTER_XLAT_CONTEXT2
macro explicitly specifies the base xlat table goes into .bss by default.
This change affects the existing SynQuacer spm_mm implementation.
plat/socionext/synquacer/include/plat.ld.S linker script intends to
locate ".bss.sp_base_xlat_table" into "sp_xlat_table" section,
but this implementation is no longer available.

This patch adds the base table section name parameter for
REGISTER_XLAT_CONTEXT2 so that platform can specify the
inner & outer WBWA & shareable memory for spm_mm base xlat table.
If PLAT_SP_IMAGE_BASE_XLAT_SECTION_NAME is not defined, base xlat table
goes into .bss by default, the result is same as before.

      TF-A: Fix BL31 linker script error · 34dd1e96
      Alexei Fedorov authored 
      

The patch fixes BL31 linker script error
"Init code ends past the end of the stacks"
for platforms with number of CPUs less than 4,
which is caused by __STACKS_END__ address being
lower than __INIT_CODE_END__.
The modified BL31 linker script detects such cases
and increases the total amount of stack memory,
setting __STACKS_END__ = __INIT_CODE_END__, and
CPUs' stacks are calculated by BL31 'plat_get_my_stack'
function accordingly. For platforms with more than 4 CPUs
and __INIT_CODE_END__ < __STACKS_END__ stack memory does not
increase and allocated CPUs' stacks match the existing
implementation.
The patch removes exclusion of PSCI initialization
functions from the reclaimed .init section in
'arm_reclaim_init.ld.S' script, which increases the
size of reclaimed memory region.

      plat/arm: Introduce TC0 platform · f5c58af6
      Usama Arif authored 
      

This patch adds support for Total Compute (TC0) platform. It is an
initial port and additional features are expected to be added later.

TC0 has a SCP which brings the primary Cortex-A out of reset
which starts executing BL1. TF-A optionally authenticates the SCP
ram-fw available in FIP and makes it available for SCP to copy.

Some of the major features included and tested in this platform
port include TBBR, PSCI, MHUv2 and DVFS.
