      sh: Use MMU.TTB register as pointer to current pgd. · 6e4662ff
      Stuart Menefy authored
      Add TTB accessor functions and give it a sensible default
      value. We will use this later for optimizing the fault

      sh: Preliminary support for SH-X2 MMU. · 21440cf0
      Paul Mundt authored
      This adds some preliminary support for the SH-X2 MMU, used by
      newer SH-4A parts (particularly SH7785).
      This MMU implements a 'compat' mode with SH-X MMUs and an
      'extended' mode for SH-X2 extended features. Extended features
      include additional page sizes (8kB, 4MB, 64MB), as well as the
      addition of page execute permissions.
      The extended mode attributes are placed in a second data array,
      which requires us to switch to 64-bit PTEs when in X2 mode.
      With the addition of the exec perms, we also overhaul the mmap
      prots somewhat, now that it's possible to handle them more

      [PATCH] sh: Drop hp690 discontig support · 65463b73
      Paul Mundt authored
      There was only one board using this (hp690 specifically), and it just so
      happens that it's only physically discontiguous at the "normal" P1 offset.  If
      we bump up the P1 offset, it's possible to hit a shadowed region of memory
      where we suddenly become magically contiguous.
      As people have been using this shadowed region workaround for quite some time
      (and without any adverse effects), it's time to drop the left over discontig
      bits that no longer have any practical use (it was always very much
      hp690-centric to begin with).

      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!
