      [MIPS] R4000/R4400 daddiu erratum workaround · 619b6e18
      Maciej W. Rozycki 提交于
       This complements the generic R4000/R4400 errata workaround code and adds 
      bits for the daddiu problem.  In most places it just modifies handwritten 
      assembly code so that the assembler is allowed to use a temporary register 
      as daddiu may now be treated as a macro that expands to a sequence of li 
      and daddu.  It is the AT register or, where AT is unavailable or used 
      explicitly for another purpose, an explicitly-named register is selected, 
      using the .set at=<reg> feature added recently to gas.  This feature is 
      only used if CONFIG_CPU_DADDI_WORKAROUNDS has been set, so if the 
      workaround remains disabled, the required version of binutils stays 
      unchanged.
      
       Similarly, daddiu instructions put in branch delay slots in noreorder 
      fragments are now taken out of them and the assembler is allowed to 
      reorder them itself as possible (which it does making the whole idea of 
      scheduling them into delay slots manually questionable).
      
       Also in the very few places where such a simple conversion was not 
      possible, a handcoded longer sequence is implemented.
      
       Other than that there are changes to code responsible for building the 
      TLB fault and page clear/copy handlers to avoid daddiu as appropriate.  
      These are only effective if the erratum is verified to be present at the 
      run time.
      
       Finally there is a trivial update to __delay(), because it uses daddiu in 
      a branch delay slot.

      [MIPS] Add basic SMARTMIPS ASE support · 9693a853
      Franck Bui-Huu 提交于
      This patch adds trivial support for SMARTMIPS extension. This extension
      is currently implemented by 4KS[CD] CPUs.
      
      Basically it saves/restores ACX register, which is part of the SMARTMIPS
      ASE, when needed. This patch does *not* add any support for Smartmips MMU
      features.
      
      Futhermore this patch does not add explicit support for 4KS[CD] CPUs since
      they are respectively mips32 and mips32r2 compliant.  So with the current
      processor configuration, a platform that has such CPUs needs to select
      both configs:
      
      	CPU_HAS_SMARTMIPS
      	SYS_HAS_CPU_MIPS32_R[12]
      
      This is due to the processor configuration which is mixing up all the
      architecture variants and the processor types.
      
      The drawback of this, is that we currently pass '-march=mips32' option to
      gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This
      can lead to a kernel image a little bit bigger than required.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
