      Add SPI-NOR framework · a13550d0
      Lionel Debieve authored
      
      
      SPI-NOR framework is based on SPI-MEM framework using
      spi_mem_op execution interface.
      
      It implements read functions and allows NOR configuration
      up to quad mode.
      Default management is 1 data line but it can be overridden
      by platform.
      It also includes specific quad mode configuration for
      Spansion, Micron and Macronix memories.

      This framework supports SPI-NAND and is based on the
      SPI-MEM framework for SPI operations. It uses a common high
      level access using the io_mtd.
      
      It is limited to the read functionalities.
      
      Default behavior is the basic one data line operation
      but it could be overridden by platform.

      Add raw NAND framework · b114abb6
      Lionel Debieve authored
      
      
      The raw NAND framework supports SLC NAND devices.
      
      It introduces a new high level interface (io_mtd) that
      defines operations a driver can register to the NAND framework.
      This interface will fill in the io_mtd device specification:
      	- device_size
              - erase_size
      that could be used by the io_storage interface.
      
      NAND core source file integrates the standard read loop that
      performs NAND device read operations using a skip bad block strategy.
      A platform buffer must be defined in case of unaligned
      data. This buffer must fit to the maximum device page size
      defined by PLATFORM_MTD_MAX_PAGE_SIZE.
      
      The raw_nand.c source file embeds the specific NAND operations
      to read data.
      The read command is a raw page read without any ECC correction.
      This can be overridden by a low level driver.
      No generic support for write or erase command or software
      ECC correction.
      
      NAND ONFI detection is available and can be enabled using
      NAND_ONFI_DETECT=1.
      For non-ONFI NAND management, platform can define required
      information.

      drivers: add a driver for snoop control unit · c20c0525
      Vishnu Banavath authored
      
      
      The SCU connects one to four Cortex-A5/Cortex-A9 processors
      to the memory system through the AXI interfaces.
      
      The SCU functions are to:
      - maintain data cache coherency between the Cortex-A5/Cortex-A9
        processors
      - initiate L2 AXI memory accesses
      - arbitrate between Cortex-A5/Cortex-A9 processors requesting
        L2 accesses
      - manage ACP accesses.
      
      Snoop Control Unit will enable to snoop on other CPUs caches.
      This is very important when it comes to synchronizing data between
      CPUs. As an example, there is a high chance that data might be
      cache'd and other CPUs can't see the change. In such cases,
      if snoop control unit is enabled, data is synchoronized immediately
      between CPUs and the changes are visible to other CPUs.
      
      This driver provides functionality to enable SCU as well as enabling
      user to know the following
      - number of CPUs present
      - is a particular CPU operating in SMP mode or AMP mode
      - data cache size of a particular CPU
      - does SCU has ACP port
      - is L2CPRESENT

      console: 16550: Prepare for skipping initialisation · cd50ffd2
      Andre Przywara authored
      
      
      On some platforms the UART might have already been initialised, for
      instance by firmware running before TF-A or by a separate management
      processor. In this case it would not be need to initialise it again
      (doing so could create spurious characters). But more importantly this
      saves us from knowing the right baudrate and the right base clock rate
      for the UART. This can lead to more robust and versatile firmware builds.
      
      Allow to skip the 16550 UART initialisation and baud rate divisor
      programming, by interpreting an input clock rate of "0" to signify this
      case. This will just skip the call to console_16550_core_init, but still
      will register the console properly.
      
      Users should just pass 0 as the second parameter, the baudrate (third
      parameter) will then be ignored as well.
      
      Fix copy & paste typos in comments for the console_16550_register()
      function on the way.

      allwinner: Convert AXP803 regulator setup code into a driver · 0bc752c9
      Samuel Holland authored
      
      
      Previously, the A64/H5 and H6 platforms' PMIC setup code was entirely
      independent. However, some H6 boards also need early regulator setup.
      
      Most of the register interface and all of the device tree traversal code
      can be reused between the AXP803 and AXP805. The main difference is the
      hardware bus interface, so that part is left to the platforms. The
      remainder is moved into a driver.
      
      I factored out the bits that were obviously specific to the AXP803;
      additional changes for compatibility with other PMICs can be made as
      needed.
      
      The only functional change is that rsb_init() now checks the PMIC's chip
      ID register against the expected value. This was already being done in
      the H6 version of the code.

      GICv3: Enable multi socket GIC redistributor frame discovery · ec834925
      Madhukar Pappireddy authored
      
      
      This patch provides declaration and definition of new GICv3 driver
      API: gicv3_rdistif_probe().This function delegates the responsibility
      of discovering the corresponding Redistributor base frame to each CPU
      itself. It is a modified version of gicv3_rdistif_base_addrs_probe()
      and is executed by each CPU in the platform unlike the previous
      approach in which only the Primary CPU did the discovery of all the
      Redistributor frames for every CPU.
      
      The flush operations as part of gicv3_driver_init() function are
      made necessary even for platforms with WARMBOOT_ENABLE_DCACHE_EARLY
      because the GICv3 driver data structure contents are accessed by CPU
      with D-Cache turned off during power down operations.

      Support larger RSA key sizes when using MBEDTLS · aacff749
      Justin Chadwell authored
      
      
      Previously, TF-A could not support large RSA key sizes as the
      configuration options passed to MBEDTLS prevented storing and performing
      calculations with the larger, higher-precision numbers required. With
      these changes to the arguments passed to MBEDTLS, TF-A now supports
      using 3072 (3K) and 4096 (4K) keys in certificates.

      Obviously, it does not exist since check_config.h is located in
      the mbedtls project.
      
      It is more sensible to use #include <...> form.

      Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__ · d5dfdeb6
      Julius Werner authored
      
      
      NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.
      
      All common C compilers predefine a macro called __ASSEMBLER__ when
      preprocessing a .S file. There is no reason for TF-A to define it's own
      __ASSEMBLY__ macro for this purpose instead. To unify code with the
      export headers (which use __ASSEMBLER__ to avoid one extra dependency),
      let's deprecate __ASSEMBLY__ and switch the code base over to the
      predefined standard.

      Code using Cryptocell specific APIs was used as part of the
      arm common board ROT support, instead of being abstracted
      in Cryptocell specific driver code, creating two problems:
      - Any none arm board that uses Cryptocell wuld need to
        copy and paste the same code.
      - Inability to cleanly support multiple versions of Cryptocell
        API and products.
      
      Move over Cryptocell specific API calls into the Cryptocell
      driver, creating abstraction API where needed.

      Factor out cross-BL API into export headers suitable for 3rd party code · 57bf6057
      Julius Werner authored
      
      
      This patch adds a new include/export/ directory meant for inclusion in
      third-party code. This is useful for cases where third-party code needs
      to interact with TF-A interfaces and data structures (such as a custom
      BL2-implementation like coreboot handing off to BL31). Directly
      including headers from the TF-A repository avoids having to duplicate
      all these definitions (and risk them going stale), but with the current
      header structure this is not possible because handoff API definitions
      are too deeply intertwined with other TF code/headers and chain-include
      other headers that will not be available in the other environment.
      
      The new approach aims to solve this by separating only the parts that
      are really needed into these special headers that are self-contained and
      will not chain-include other (non-export) headers. TF-A code should
      never include them directly but should instead always include the
      respective wrapper header, which will include the required prerequisites
      (like <stdint.h>) before including the export header. Third-party code
      can include the export headers via its own wrappers that make sure the
      necessary definitions are available in whatever way that environment can
      provide them.

      Rework the macro that eases the table definition: the src and msk fields

      Some macros had then to be modified: _USART1_SEL, _ASS_SEL and _MSS_SEL to
      _UART1_SEL, _AXIS_SEL, and _MCUS_SEL to match register fields.
      
      Note: the mask for RCC_ASSCKSELR_AXISSRC is changed from 0x3 to 0x7
      to reflect the size of the register field, even if there are only
      3 possible clock sources.
      
      The mask value is also corrected for QSPI and FMC clock selection.

      Fix type of cot_desc_ptr · 2efb7ddc
      Sandrine Bailleux authored
      
      
      The chain of trust description and the pointer pointing to its first
      element were incompatible, thus requiring an explicit type cast for
      the assignment.
      
      - cot_desc was an array of
        const pointers to const image descriptors.
      
      - cot_desc_ptr was a const pointer to
        (non-constant) pointers to const image descriptors.
      
      Thus, trying to assign cot_desc to cot_desc_ptr (with no cast) would
      generate the following compiler warning:
