      arm: Switch to -mno-unaligned-access when supported by the compiler · 1551df35
      Tom Rini authored
      When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
      matter) it assumes a default of SCTRL.A being cleared and unaligned
      accesses being allowed and fast at the hardware level.  We set this bit
      and must pass along -mno-unaligned-access so that the compiler will
      still breakdown accesses and not trigger a data abort.
      
      To better help understand the requirements of the project with respect
      to unaligned memory access, the
      Documentation/unaligned-memory-access.txt file has been added as
      doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
      tag of the kernel.
