      plat/arm: Fix build failure due to increase in BL2 size · fdf50a25
      Manish V Badarkhe authored
      
      
      BL2 size gets increased due to the libfdt library update and 
      that eventually cause no-optimization build failure for BL2 as below:
      aarch64-none-elf-ld.bfd: BL2 image has exceeded its limit.
      aarch64-none-elf-ld.bfd: region `RAM' overflowed by 4096 bytes
      Makefile:1070: recipe for target 'build/fvp/debug/bl2/bl2.elf' failed
      make: *** [build/fvp/debug/bl2/bl2.elf] Error 1
      
      Fixed build failure by increasing BL2 image size limit by 4Kb.

      plat/arm, dts: Update platform device tree for CoT · 2a0ef943
      Manish V Badarkhe authored
      
      
      Included cot_descriptors.dtsi in platform device tree
      (fvp_tb_fw_config.dts).
      
      Also, updated the maximum size of tb_fw_config to 0x1800
      in order to accomodate the device tree for CoT descriptors.
      
      Follow up patch will parse the device tree for these CoT descriptors
      and fill the CoT descriptor structures at runtime instead of using
      static CoT descriptor structures in the code base.

      corstone700: splitting the platform support into FVP and FPGA · ef93cfa3
      Abdellatif El Khlifi authored
      
      
      This patch performs the following:
      
      - Creating two corstone700 platforms under corstone700 board:
      
        fvp and fpga
      
      - Since the FVP and FPGA have IP differences, this commit provides a specific DTS for each platform
      - The platform can be specified using the TARGET_PLATFORM Makefile variable
      (possible values are: fvp or fpga)
      - Allowing to use u-boot by:
        - Enabling NEED_BL33 option
        - Fixing non-secure image base: For no preloaded bl33 we want to
          have the NS base set on shared ram. Setup a memory map region
          for NS in shared map and set the bl33 address in the area.
      - Setting the SYS_COUNTER_FREQ_IN_TICKS based on the selected
      platform
      - Setting ARM_MAP_SHARED_RAM and ARM_MAP_NS_SHARED_RAM to use MT_MEMORY

      arm_fpga: Fix MPIDR topology checks · 53baf7f0
      Andre Przywara authored
      
      
      The plat_core_pos_by_mpidr() implementation for the Arm FPGA port has
      some issues, which leads to problems when matching GICv3 redistributors
      with cores:
      - The power domain tree was not taking multithreading into account, so
        we ended up with the wrong mapping between MPIDRs and core IDs.
      - Before even considering an MPIDR, we try to make sure Aff2 is 0.
        Unfortunately this is the cluster ID when the MT bit is set.
      - We mask off the MT bit in MPIDR, before basing decisions on it.
      - When detecting the MT bit, we are properly calculating the thread ID,
        but don't account for the shift in the core and cluster ID checks.
      
      Those problems lead to early rejections of MPIDRs values, in particular
      when called from the GIC code. As a result, CPU_ON for secondary cores
      was failing for most of the cores.
      
      Fix this by properly handling the MT bit in plat_core_pos_by_mpidr(),
      also pulling in FPGA_MAX_PE_PER_CPU when populating the power domain
      tree.

      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.

      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.

      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.

      arm_fpga: Read UART address from DT · dee3042c
      Andre Przywara authored
      
      
      The arm_fpga port requires a DTB, to launch a BL33 payload.
      To make this port more flexible, we can also use the information in the
      DT to configure the console driver.
      For a start, find the DT node pointed to by the stdout-path property, and
      read the base address from there.
      This assumes for now that the stdout-path points to a PL011 UART.
      
      This allows to remove platform specific addresses from the image. We
      keep the original base address for the crash console.

      Every DT would contain a node for the GIC(v3) interrupt controller, so
      we can read the base address for the distributor and redistributors from
      there.
      
      This avoids hard coding this information in the code and allows for a more

      The stdout-path property in the /chosen node of a DTB points to a device

      On most (if not all) ARM based platforms this is the debug UART.
      The ST platform code contains a function to parse this property and
      chase down eventual aliases to learn the node offset of this UART node.
      
      Introduce a slightly more generalised version of this ST platform function
      in the generic fdt_wrappers code. This will be useful for other platforms
      as well.

      Andre Przywara authored
      
      
      The ARM Generic Timer DT binding describes an (optional) property to
      declare the counter frequency. Its usage is normally discouraged, as the
      value should be read from the CNTFRQ_EL0 system register.
      
      However in our case we can use it to program this register in the first
      place, which avoids us to hard code a counter frequency into the code.
      We keep some default value in, if the DT lacks that property for
      whatever reason.

      arm: fconf: Fix GICv3 dynamic configuration · 364ad245
      Andre Przywara authored
      
      
      At the moment the fconf_populate_gicv3_config() implementation is
      somewhat incomplete: First it actually fails to store the retrieved
      information (the local addr[] array is going nowhere), but also it makes
      quite some assumptions about the device tree passed to it: it needs to
      use two address-cells and two size-cells, and also requires all five
      register regions to be specified, where actually only the first two
      are mandatory according to the binding (and needed by our code).
      
      Fix this by introducing a proper generic function to retrieve "reg"
      property information from a DT node:
      We retrieve the #address-cells and #size-cells properties from the
      parent node, then use those to extract the right values from the "reg"
      property. The function takes an index to select one region of a reg
      property.
      
      This is loosely based on the STM32 implementation using "reg-names",
      which we will subsume in a follow-up patch.

      fconf: Update dyn_config compatible string · 592c396d
      Louis Mayencourt authored
      
      
      Dynamic configuration properties are fconf properties. Modify the
      compatible string from "arm,.." to "fconf,.." to reflect this.

      fdt/wrappers: Replace fdtw_read_cells() implementation · ff4e6c35
      Andre Przywara authored
      Our fdtw_read_cells() implementation goes to great lengths to
      sanity-check every parameter and result, but leaves a big hole open:
      The size of the storage the value pointer points at needs to match the
      number of cells given. This can't be easily checked at compile time,
      since we lose the size information by using a void pointer.
      Regardless the current usage of this function is somewhat wrong anyways,
      since we use it on single-element, fixed-length properties only, for
      which the DT binding specifies the size.
      Typically we use those functions dealing with a number of cells in DT
      context to deal with *dynamically* sized properties, which depend on
      other properties (#size-cells, #clock-cells, ...), to specify the number
      of cells needed.
      
      Another problem with the current implementation is the use of
      ambiguously sized types (uintptr_t, size_t) together with a certain
      expectation about their size. In general there is no relation between
      the length of a DT property and the bitness of the code that parses the
      DTB: AArch64 code could encounter 32-bit addresses (where the physical
      address space is limited to 4GB [1]), while AArch32 code could read
      64-bit sized properties (/memory nodes on LPAE systems, [2]).
      
      To make this more clear, fix the potential issues and also align more
      with other DT users (Linux and U-Boot), introduce functions to explicitly
      read uint32 and uint64 properties. As the other DT consumers, we do this
      based on the generic "read array" function.
      Convert all users to use either of those two new functions, and make
      sure we never use a pointer to anything other than uint32_t or uint64_t
      variables directly.
      
      This reveals (and fixes) a bug in plat_spmd_manifest.c, where we write
      4 bytes into a uint16_t variable (passed via a void pointer).
      
      Also we change the implementation of the function to better align with
      other libfdt users, by using the right types (fdt32_t) and common
      variable names (*prop, prop_names).

      fdt/wrappers: Generalise fdtw_read_array() · 6e3a89f4
      Andre Przywara authored
      
      
      Currently our fdtw_read_array() implementation requires the length of
      the property to exactly match the requested size, which makes it less
      flexible for parsing generic device trees.
      Also the name is slightly misleading, since we treat the cells of the
      array as 32 bit unsigned integers, performing the endianess conversion.
      
      To fix those issues and align the code more with other DT users (Linux
      kernel or U-Boot), rename the function to "fdt_read_uint32_array", and
      relax the length check to only check if the property covers at least the
      number of cells we request.
      This also changes the variable names to be more in-line with other DT
      users, and switches to the proper data types.
      
      This makes this function more useful in later patches.
