[U-Boot] [PATCH v2 0/8] add clang support for some ARM boards

[Jeroen Hofstee]

Changes since v1 (RFC):
  - Update the commit message for -Werror when polling for cc-options.
    As pointed out by Masahiro this is not needed for all arguments,
    but only for warning options.
  - drop SOC specific patch from this patchset, I will post it seperately.
  - Do implement get_gd for AARCH64.
  - Drop the memset patch for clearing gd / not reassinging gd and use
    Simon his version.
  - Drop the patch for using gnu inline version, since targets using the
    generic board no longer need it.
  - Limit update gd in board_init_r to ARM / ARM64, since powerpc does
    need it.
  - change __inline to inline and drop volatile from get_gd to make
    checkpatch happy.
  - add patch workaround for generated constants
  - add patch default to cc for host compiler
  - update README.clang
  - add SOB / cc
