      rpi3: Make SHARED_RAM optional · a95e6415
      Andre Przywara authored
      
      
      The existing Raspberry Pi 3 port sports a number of memory regions,
      which are used for several purposes. The upcoming RPi4 port will not use
      all of those, so make the SHARED_RAM region optional, by only mapping it
      if it has actually been defined. This helps to get a cleaner RPi4 port.

      rpi3: Rename RPI3_IO_BASE to RPI_IO_BASE · 110fd1fe
      Andre Przywara authored
      
      
      The location of the MMIO window is different between a Raspberry Pi 3
      and 4: the former has it just below 1GB, the latter below 4GB.
      The relative location of the peripherals is mostly compatible though.
      
      To allow sharing code between the two models, let's rename the symbol
      used for the MMIO base to the more generic RPI_IO_BASE name.

      rpi3: Move shared rpi3 files into common directory · 4f2b9848
      Andre Przywara authored
      
      
      To be able to share code more easily between the existing Raspberry Pi 3
      and the upcoming Raspberry Pi 4 platform, move some code which is not
      board specific into a "common" directory.

      qemu: Move and generalise FDT PSCI fixup · f240728b
      Andre Przywara authored
      
      
      The QEMU platform port scans its device tree to advertise PSCI as the
      CPU enable method. It does this by scanning *every* node in the DT and
      check whether its compatible string starts with "arm,cortex-a". Then it
      sets the enable-method to PSCI, if it doesn't already have one.
      
      Other platforms might want to use this functionality as well, so let's
      move it out of the QEMU platform directory and make it more robust by
      fixing some shortcomings:
      - A compatible string starting with a certain prefix is not a good way
      to find the CPU nodes. For instance a "arm,cortex-a72-pmu" node will
      match as well and is in turn favoured with an enable-method.
      - If the DT already has an enable-method, we won't change this to PSCI.
      
      Those two issues will for instance fail on the Raspberry Pi 4 DT.
      To fix those problems, we adjust the scanning method:
      The DT spec says that all CPU nodes are subnodes of the mandatory
      /cpus node, which is a subnode of the root node. Also each CPU node has
      to have a device_type = "cpu" property. So we find the /cpus node, then
      scan for a subnode with the proper device_type, forcing the
      enable-method to "psci".
      We have to restart this search after a property has been patched, as the
      node offsets might have changed meanwhile.
      
      This allows this routine to be reused for the Raspberry Pi 4 later.

      rpi3: Move rpi3_hw.h header file to include/rpi_hw.h · 4666d046
      Andre Przywara authored
      
      
      With the advent of Raspberry Pi 4 support, we need to separate some
      board specific headers between the RPi3 and RPi4.
      Rename and move the "rpi3_hw.h" header, so that .c files just include
      rpi_hw.h, and automatically get the correct version.

      rpi3: Add "rpi" platform directory · ab13addd
      Andre Przywara authored
      
      
      With the incoming support for the Raspberry Pi 4 boards, one directory
      to serve both versions will not end up well.
      
      Create an additional layer by inserting a "rpi" directory betweeen /plat
      and rpi3, so that we can more easily share or separate files between the
      two later.

      Add UBSAN support and handlers · 1f461979
      Justin Chadwell authored
      
      
      This patch adds support for the Undefined Behaviour sanitizer. There are
      two types of support offered - minimalistic trapping support which
      essentially immediately crashes on undefined behaviour and full support
      with full debug messages.
      
      The full support relies on ubsan.c which has been adapted from code used
      by OPTEE.
