      Kumar Gala 提交于
      The new e500mc core from Freescale is based on the e500v2 but with the
      following changes:
      
      * Supports only the Enhanced Debug Architecture (DSRR0/1, etc)
      * Floating Point
      * No SPE
      * Supports lwsync
      * Doorbell Exceptions
      * Hypervisor
      * Cache line size is now 64-bytes (e500v1/v2 have a 32-byte cache line)

      [PATCH] powerpc: Merge cacheflush.h and cache.h · 26ef5c09
      David Gibson 提交于
      The ppc32 and ppc64 versions of cacheflush.h were almost identical.
      The two versions of cache.h are fairly similar, except for a bunch of
      register definitions in the ppc32 version which probably belong better
      elsewhere.  This patch, therefore, merges both headers.  Notable
      points:
      	- there are several functions in cacheflush.h which exist only
      on ppc32 or only on ppc64.  These are handled by #ifdef for now, but
      these should probably be consolidated, along with the actual code
      behind them later.
      	- Confusingly, both ppc32 and ppc64 have a
      flush_dcache_range(), but they're subtly different: it uses dcbf on
      ppc32 and dcbst on ppc64, ppc64 has a flush_inval_dcache_range() which
      uses dcbf.  These too should be merged and consolidated later.
      	- Also flush_dcache_range() was defined in cacheflush.h on
      ppc64, and in cache.h on ppc32.  In the merged version it's in
      cacheflush.h
      	- On ppc32 flush_icache_range() is a normal function from
      misc.S.  On ppc64, it was wrapper, testing a feature bit before
      calling __flush_icache_range() which does the actual flush.  This
      patch takes the ppc64 approach, which amounts to no change on ppc32,
      since CPU_FTR_COHERENT_ICACHE will never be set there, but does mean
      renaming flush_icache_range() to __flush_icache_range() in
      arch/ppc/kernel/misc.S and arch/powerpc/kernel/misc_32.S
      	- The PReP register info from asm-ppc/cache.h has moved to
      arch/ppc/platforms/prep_setup.c
      	- The 8xx register info from asm-ppc/cache.h has moved to a
      new asm-powerpc/reg_8xx.h, included from reg.h
      	- flush_dcache_all() was defined on ppc32 (only), but was
      never called (although it was exported).  Thus this patch removes it
      from cacheflush.h and from ARCH=powerpc (misc_32.S) entirely.  It's
      left in ARCH=ppc for now, with the prototype moved to ppc_ksyms.c.
