      plat/sgi: allow usage of secure partions on rdn2 platform · c0d55ef7
      Omkar Anand Kulkarni authored 
      

Add the secure partition mmap table and the secure partition boot
information to support secure partitions on RD-N2 platform. In addition
to this, add the required memory region mapping for accessing the
SoC peripherals from the secure partition.

      board/rdv1mc: initialize tzc400 controllers · f97b5795
      Aditya Angadi authored 
      

A TZC400 controller is placed inline on DRAM channels and regulates
the secure and non-secure accesses to both secure and non-secure
regions of the DRAM memory. Configure each of the TZC controllers
across the Chips.

For use by secure software, configure the first chip's trustzone
controller to protect the upper 16MB of the memory of the first DRAM
block for secure accesses only. The other regions are configured for
non-secure read write access. For all the remote chips, all the DRAM
regions are allowed for non-secure read and write access.

      plat/sgi: allow access to TZC controller on all chips · 21803491
      Aditya Angadi authored 
      

On a multi-chip platform, the boot CPU on the first chip programs the
TZC controllers on all the remote chips. Define a memory region map for
the TZC controllers for all the remote chips and include it in the BL2
memory map table.

In addition to this, for SPM_MM enabled multi-chip platforms, increase
the number of mmap entries and xlat table counts for EL3 execution
context as well because the shared RAM regions and GIC address space of
remote chips are accessed.

      plat/sgi: define memory regions for multi-chip platforms · 05b5c417
      Aditya Angadi authored 
      

For multi-chip platforms, add a macro to define the memory regions on
chip numbers >1 and its associated access permissions. These memory
regions are marked with non-secure access.

      plat/sgi: allow access to nor2 flash and system registers from s-el0 · 5dae6bc7

Allow the access of system registers and nor2 flash memory region
from s-el0. This allows the secure parititions residing at s-el0
to access these memory regions.

      plat/sgi: define default list of memory regions for dmc620 tzc · b4d548f1
      Thomas Abraham authored 
      

Define a default DMC-620 TZC memory region configuration and use it to
specify the TZC memory regions on sgi575, rdn1edge and rde1edge
platforms. The default DMC-620 TZC memory regions are defined
considering the support for secure paritition as well.

      plat/sgi: improve macros defining cper buffer memory region · d306eb80
      Thomas Abraham authored 
      

Remove the 'ARM_' prefix from the macros defining the CPER buffer memory
and replace it with 'CSS_SGI_' prefix. These macros are applicable only
for platforms supported within plat/sgi. In addition to this, ensure
that these macros are defined only if the RAS_EXTENSION build option is
enabled.

      plat/sgi: refactor DMC-620 error handling SMC function id · 513ba5c9
      Thomas Abraham authored 
      

The macros defining the SMC function ids for DMC-620 error handling are
listed in the sgi_base_platform_def.h header file. But these macros are
not applicable for all platforms supported under plat/sgi. So move these
macro definitions to sgi_ras.c file in which these are consumed. While
at it, remove the AArch32 and error injection function ids as these are
unused.

- i2c_probe()
- i2c_set_bus_speed() Set the I2C bus speed
- i2c_get_bus_speed() Get the current bus speed
- i2c_recv_byte() Receive one byte of data.
- i2c_send_byte() Send one byteof data
- i2c_read_byte() Read single byte of data
- i2c_read() Read multiple bytes of data
- i2c_write_byte Write single byte of data
- i2c_write() Write multiple bytes of data

This driver is verified by reading the DDR SPD data.

      allwinner: A64: Limit FDT checks to reduce code size · 8fa5592b
      Andre Przywara authored 
      

The upcoming refactoring to support the new H616 SoCs will push the A64
build over the edge, by using more than the 48KB of SRAM available.

To reduce the code size, set some libfdt options that aim to reduce
sanity checks (for saving code space):
- ASSUME_LATEST: only allow v17 DTBs (as created by dtc)
- ASSUME_NO_ROLLBACK: don't prepare for failed DT additions
- ASSUME_LIBFDT_ORDER: assume sane ordering, as done by dtc

      SPM: declare third cactus instance as UP SP · e96fc8e7
      Olivier Deprez authored 
      

The FF-A v1.0 spec allows two configurations for the number of EC/vCPU
instantiated in a Secure Partition:
-A MultiProcessor (MP) SP instantiates as many ECs as the number of PEs.
An EC is pinned to a corresponding physical CPU.
-An UniProcessor (UP) SP instantiates a single EC. The EC is migrated to
the physical CPU from which the FF-A call is originating.
This change permits exercising the latter case within the TF-A-tests
framework.
