      plat/arm: Migrate AArch64 port to the multi console driver · 2f18aa1f
      Antonio Nino Diaz authored
      
      
      The old API is deprecated and will eventually be removed.
      
      Arm platforms now use the multi console driver for boot and runtime
      consoles. However, the crash console uses the direct console API because
      it doesn't need any memory access to work. This makes it more robust
      during crashes.
      
      The AArch32 port of the Trusted Firmware doesn't support this new API
      yet, so it is only enabled in AArch64 builds. Because of this, the
      common code must maintain compatibility with both systems. SP_MIN
      doesn't have to be updated because it's only used in AArch32 builds.
      The TSP is only used in AArch64, so it only needs to support the new
      API without keeping support for the old one.
      
      Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
      causes the UARTs to reset (except for the one used by the TSP). This
      means that they must be unregistered when suspending and re-registered
      when resuming. This wasn't a problem with the old driver because it just
      restarted the UART, and there were no problems associated with
      registering and unregistering consoles.
      
      The size of BL31 has been increased in builds with SPM.

      ARM platforms: Demonstrate mem_protect from el3_runtime · 638b034c
      Roberto Vargas authored
      
      
      Previously mem_protect used to be only supported from BL2. This is not
      helpful in the case when ARM TF-A BL2 is not used. This patch demonstrates
      mem_protect from el3_runtime firmware on ARM Platforms specifically
      when RESET_TO_BL31 or RESET_TO_SP_MIN flag is set as BL2 may be absent
      in these cases. The Non secure DRAM is dynamically mapped into EL3 mmap
      tables temporarily and then the protected regions are then cleared. This
      avoids the need to map the non secure DRAM permanently to BL31/sp_min.
      
      The stack size is also increased, because DYNAMIC_XLAT_TABLES require
      a bigger stack.

      types: use int-ll64 for both aarch32 and aarch64 · 0a2d5b43
      Masahiro Yamada authored
      Since commit 031dbb12
      
       ("AArch32: Add essential Arch helpers"),
      it is difficult to use consistent format strings for printf() family
      between aarch32 and aarch64.
      
      For example, uint64_t is defined as 'unsigned long long' for aarch32
      and as 'unsigned long' for aarch64.  Likewise, uintptr_t is defined
      as 'unsigned int' for aarch32, and as 'unsigned long' for aarch64.
      
      A problem typically arises when you use printf() in common code.
      
      One solution could be, to cast the arguments to a type long enough
      for both architectures.  For example, if 'val' is uint64_t type,
      like this:
      
        printf("val = %llx\n", (unsigned long long)val);
      
      Or, somebody may suggest to use a macro provided by <inttypes.h>,
      like this:
      
        printf("val = %" PRIx64 "\n", val);
      
      But, both would make the code ugly.
      
      The solution adopted in Linux kernel is to use the same typedefs for
      all architectures.  The fixed integer types in the kernel-space have
      been unified into int-ll64, like follows:
      
          typedef signed char           int8_t;
          typedef unsigned char         uint8_t;
      
          typedef signed short          int16_t;
          typedef unsigned short        uint16_t;
      
          typedef signed int            int32_t;
          typedef unsigned int          uint32_t;
      
          typedef signed long long      int64_t;
          typedef unsigned long long    uint64_t;
      
      [ Linux commit: 0c79a8e29b5fcbcbfd611daf9d500cfad8370fcf ]
      
      This gets along with the codebase shared between 32 bit and 64 bit,
      with the data model called ILP32, LP64, respectively.
      
      The width for primitive types is defined as follows:
      
                         ILP32           LP64
          int            32              32
          long           32              64
          long long      64              64
          pointer        32              64
      
      'long long' is 64 bit for both, so it is used for defining uint64_t.
      'long' has the same width as pointer, so for uintptr_t.
      
      We still need an ifdef conditional for (s)size_t.
      
      All 64 bit architectures use "unsigned long" size_t, and most 32 bit
      architectures use "unsigned int" size_t.  H8/300, S/390 are known as
      exceptions; they use "unsigned long" size_t despite their architecture
      is 32 bit.
      
      One idea for simplification might be to define size_t as 'unsigned long'
      across architectures, then forbid the use of "%z" string format.
      However, this would cause a distortion between size_t and sizeof()
      operator.  We have unknowledge about the native type of sizeof(), so
      we need a guess of it anyway.  I want the following formula to always
      return 1:
      
        __builtin_types_compatible_p(size_t, typeof(sizeof(int)))
      
      Fortunately, ARM is probably a majority case.  As far as I know, all
      32 bit ARM compilers use "unsigned int" size_t.

      plat/arm: Add MHUv2 support to SCMI driver · a427785c
      Samarth Parikh authored
      
      
      Currently the SCMI driver supports MHUv1, but Arm platforms may have
      varied versions of MHU driver, with MHUv2 controllers being in the
      latest Arm platforms.
      
      This patch updates the SCMI driver to support MHUv2, specifically that
      the sender must send the wake-up to the receiver before initiating any
      data transfer.
      
      Also, the existing mhu driver files, css_mhu.c and css_mhu.h, have been
      moved from the scpi directory to a new directory, css/drivers/mhu.

      * Overflow error of 4096 bytes for rsa algorithm.
      * Overflow error of 8192 bytes for ecdsa algorithm.
      * Overflow error of 4096 bytes for rsa+ecdsa algorithm.
      * Overflow error of 4096 bytes for non-TBBR case.
      
      So this patch increments macro PLAT_ARM_MAX_BL2_SIZE for all the above

      FVP: Fix function for translating MPIDR to linear index · 468bea41
      David Cunado authored
      The current AArch32 version of plat_arm_calc_core_pos uses an incorrect
      algorithm to calculate the linear position of a core / PE from its
      MPIDR.
      
      This patch corrects the algorithm to:
      
      (ClusterId * FVP_MAX_CPUS_PER_CLUSTER) * FVP_MAX_PE_PER_CPU
      + (CPUId * FVP_MAX_PE_PER_CPU)
      + ThreadId
      
      which supports cores where there are more than 1 PE per CPU.
      
      NOTE: the AArch64 version was fixed in 39b21d19

      qemu: don't use C functions for the crash console callbacks · 0e24ea81
      Michalis Pappas authored
      
      
      Use the console_pl011_core_* functions directly in the crash console
      callbacks.
      
      This bypasses the MULTI_CONSOLE_API for the crash console (UART1), but
      allows using the crash console before the C runtime has been initialized
      (eg to call ASM_ASSERT). This retains backwards compatibility with respect
      to functionality when the old API is used.
      
      Use the MULTI_CONSOLE_API to register UART0 as the boot and runtime
      console.

      Clean usage of void pointers to access symbols · 9f85f9e3
      Joel Hutton authored
      
      
      Void pointers have been used to access linker symbols, by declaring an
      extern pointer, then taking the address of it. This limits symbols
      values to aligned pointer values. To remove this restriction an
      IMPORT_SYM macro has been introduced, which declares it as a char
      pointer and casts it to the required type.

      rpi3: Use new console APIs · e0f21f62
      Antonio Nino Diaz authored
      
      
      Switch to the new console APIs enabled by setting MULTI_CONSOLE_API=1.
      
      The crash console doesn't use this API, it uses internally the core
      functions of the 16550 console.
      
      `bl31_plat_runtime_setup` is no longer needed. When this platform port
      was introduced, that function used to disable the console. It was needed
      to override that behaviour. The new behaviour is to switch to the
      runtime console. The console is registered for all scopes (boot, crash
      and runtime) in `rpi3_console_init` so it is not needed to override the
      default behaviour anymore.
      
      Update documentation.
