      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.

      For multi-chip platforms, add a macro to define the memory regions on

      regions are marked with non-secure access.

      that these macros are defined only if the RAS_EXTENSION build option is

      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.

      allwinner: Add Allwinner H616 SoC support · 26123ca3
      Andre Przywara authored
      
      
      The new Allwinner H616 SoC lacks the management controller and the secure
      SRAM A2, so we need to tweak the memory map quite substantially:
      We run BL31 in DRAM. Since the DRAM starts at 1GB, we cannot use our
      compressed virtual address space (max 256MB) anymore, so we revert to
      the full 32bit VA space and use a flat mapping throughout all of it.
      
      The missing controller also means we need to always use the native PSCI
      ops, using the CPUIDLE hardware, as SCPI and suspend depend on the ARISC.

      allwinner: Express memmap more dynamically · 01cec8f4
      Andre Przywara authored
      
      
      In preparation for changing the memory map, express the locations of the
      various code and data pieces more dynamically, allowing SoCs to override
      the memmap later.
      Also prepare for the SCP region to become optional.
      
      No functional change.

      allwinner: Move sunxi_cpu_power_off_self() into platforms · 9227719d
      Andre Przywara authored
      
      
      The code to power the current core off when SCPI is not available is now
      different for the two supported SoC families.
      To make adding new platforms easier, move sunxi_cpu_power_off_self()
      into the SoC directory, so we don't need to carry definitions for both
      methods for all SoCs.
      
      On the H6 we just need to trigger the CPUIDLE hardware, so can get rid
      of all the code to program the ARISC, which is now only needed for the
      A64 version.

      allwinner: Move SEPARATE_NOBITS_REGION to platforms · eb15bdaa
      Andre Przywara authored
      
      
      For the existing SoCs we support, we use SEPARATE_NOBITS_REGION, to move
      some parts of the data into separate memory regions (to save on the SRAM
      A2 we are loaded into).
      For the upcoming H616 platform this is of no concern (we run in DRAM),
      so make this flag a platform choice instead.
