      Don't return error information from console_flush · 831b0e98

      And from crash_console_flush.
      
      We ignore the error information return by console_flush in _every_
      place where we call it, and casting the return type to void does not
      work around the MISRA violation that this causes. Instead, we collect
      the error information from the driver (to avoid changing that API), and
      don't return it to the caller.

      TF-A GICv2 driver: Introduce makefile · 1322dc94

      This patch moves all GICv2 driver files into new added

      NOTE: Usage of 'drivers/arm/gic/common/gic_common.c' file
      is now deprecated and platforms with GICv2 driver need to

      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

      static CoT descriptor structures in the code base.

      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.

      fdt/wrappers: Introduce code to find UART DT node · 60e2e27d
      Andre Przywara authored
      
      
      The stdout-path property in the /chosen node of a DTB points to a device
      node, which is used for boot console output.
      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.

      The STM32 platform port parse DT nodes to find base address to
      peripherals. It does this by using its own implementation, even though
      this functionality is generic and actually widely useful outside of the
      STM32 code.
      
      Re-implement fdt_get_reg_props_by_name() on top of the newly introduced
      fdt_get_reg_props_by_index() function, and move it to fdt_wrapper.c.
      This is removes the assumption that #address-cells and #size-cells are
      always one.

      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.

      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).
