      plat/arm: Increase size of firmware configuration area · ce4ca1a8
      Manish V Badarkhe authored 
      

Increased the size of firmware configuration area to accommodate
all configs.

Updated maximum size of following bootloaders due to increase
in firmware configs size and addition of the code in the BL2.

1. Increased maximum size of BL2 for Juno platform in no
   optimisation case.
2. Reduced maximum size of BL31 for fvp and Juno platform.
3. Reduced maximum size of BL32 for Juno platform.

      plat/arm: Load and populate fw_config and tb_fw_config · 82869675
      Manish V Badarkhe authored 
      

Modified the code to do below changes:

1. Load tb_fw_config along with fw_config by BL1.
2. Populate fw_config device tree information in the
   BL1 to load tb_fw_config.
3. In BL2, populate fw_config information to retrieve
   the address of tb_fw_config and then tb_fw_config
   gets populated using retrieved address.
4. Avoid processing of configuration file in case of error
   value returned from "fw_config_load" function.
5. Updated entrypoint information for BL2 image so
   that it's arg0 should point to fw_config address.

      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.
