      MIPS: BCM5xxx: Remove dead init_fpu code · b1013f1e
      Paul Burton authored
      The BMIPS5xxx core_init function contains a call to an init_fpu function
      inside an #ifdef whose condition never evaluates true. Remove the dead
      code. FPU initialization happens later, primarily when a userland
      program attempts to use it.

      MIPS: Hide CONFIG_MIPS_O32_FP64_SUPPORT prompt for >= MIPSr6 · b7f1e273
      Paul Burton authored
      From MIPSr6 onwards FP64 support is mandatory, and so
      CONFIG_MIPS_O32_FP64_SUPPORT is always selected for configurations which
      support O32 binaries. Hide the useless unchangeable prompt in these
      cases.

      MIPS: Hardcode cpu_has_mmips=1 for microMIPS kernels · a013ba39
      Paul Burton authored
      If we built the kernel targeting the microMIPS ISA then the very fact
      that the kernel is running implies that the CPU supports microMIPS. Thus
      we can hardcode cpu_has_mmips to 1 allowing the compiler greater scope
      for optimisation due to the compile-time constant.

      MIPS: Simplify GCC_OFF_SMALL_ASM definition · d08b8ccc
      Paul Burton authored
      The GCC_OFF_SMALL_ASM macro defines the constraint to use for
      instructions needing "small offsets", typically the LL or SC
      instructions. Historically these had 16 bit offsets, but microMIPS &
      MIPS32/MIPS64r6 onwards reduced the width of the offset field.
      
      GCC 4.9 & higher supports a ZC constraint which matches the offset
      requirements of the LL & SC instructions. Where supported we can use
      the ZC constraint regardless of ISA, and it will handle the requirements
      of the ISA correctly. As such we require 3 cases:
      
        - GCC 4.9 & higher can use ZC.
      
        - GCC older than 4.9 must use the older R constraint, which does not
          take into account microMIPS or MIPSr6.
      
        - microMIPS builds therefore require GCC 4.9 or higher. MIPSr6 support
          was only introduced in newer compilers anyway so it can be ignored
          here.
      
      The current code complicates this a little by specifically having MIPSr6
      bypass the GCC version check, and using the R constraint for pre-MIPSr6
      builds even if the compiler supports ZC which would be equivalent.
      
      Simplify this such that the code straightforwardly implements the 3
      cases outlined above.
      
      For non-GCC compilers we presume that ZC is safe to use. In practice the
      only non-GCC compiler of interest is clang and it has supported the ZC
      constraint since version 3.7.0. It seems safe enough to presume that
      nobody will expect to built a working kernel using a clang version older
      than that, and if they do then they'll have bigger problems. As such we
      don't check the clang version number & just presume ZC is usable when
      the compiler is not GCC.

      MIPS: Remove GCC_IMM_ASM & GCC_REG_ACCUM macros · 57810ecb
      Paul Burton authored
      asm/compiler.h defined GCC_IMM_ASM & GCC_REG_ACCUM macros, both of which
      are defined differently for GCC pre-3.4 or GCC 3.4 & higher. We only
      support building with GCC 4.6 & higher since commit cafa0010 ("Raise
      the minimum required gcc version to 4.6"), which makes the pre-3.4
      definition dead code.
      
      Rather than leave the macro definitions around, inline the GCC 3.4 &
      higher definitions into the single file that uses them & remove the
      macros entirely.
