      coreboot: Use generic base address · e21a788e
      Andre Przywara authored
      
      
      Since now the generic console_t structure holds the UART base address as
      well, let's use that generic location for the coreboot memory console.
      This removes the base member from the coreboot specific data structure,
      but keeps the struct console_cbmc_t and its size member.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored
      Enforce full include path for includes. Deprecate old paths.
      
      The following folders inside include/lib have been left unchanged:
      
      - include/lib/cpus/${ARCH}
      - include/lib/el3_runtime/${ARCH}
      
      The reason for this change is that having a global namespace for
      includes isn't a good idea. It defeats one of the advantages of having
      folders and it introduces problems that are sometimes subtle (because
      you may not know the header you are actually including if there are two
      of them).
      
      For example, this patch had to be created because two headers were
      called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
      to avoid collision."). More recently, this patch has had similar
      problems: 46f9b2c3 ("drivers: add tzc380 support").
      
      This problem was introduced in commit 4ecca339
      
       ("Move include and
      source files to logical locations"). At that time, there weren't too
      many headers so it wasn't a real issue. However, time has shown that
      this creates problems.
      
      Platforms that want to preserve the way they include headers may add the
      removed paths to PLAT_INCLUDES, but this is discouraged.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored
      
      
      All identifiers, regardless of use, that start with two underscores are
      reserved. This means they can't be used in header guards.
      
      The style that this project is now to use the full name of the file in
      capital letters followed by 'H'. For example, for a file called
      "uart_example.h", the header guard is UART_EXAMPLE_H.
      
      The exceptions are files that are imported from other projects:
      
      - CryptoCell driver
      - dt-bindings folders
      - zlib headers

      coreboot: Add support for CBMEM console · 1c5f5031
      Julius Werner authored
      
      
      coreboot supports an in-memory console to store firmware logs even when
      no serial console is available. It is widely supported by
      coreboot-compatible bootloaders (including SeaBIOS and GRUB) and can be
      read by the Linux kernel.
      
      This patch allows BL31 to add its own log messages to this console. The
      driver will be registered automatically if coreboot support is compiled
      in and detects the presence of a console buffer in the coreboot tables.
