CRIS: Segmented addressing only for kernel mode.

Segmented translation through the CRIS MMU is only done for
accesses in kernel mode. In user-mode, all accesses are treated
as paged regardless of the mode config in RW_MM_CFG.

Clean up debugging code #ifdefs (Eduardo Habkost)

Use macros to avoid #ifdefs on debugging code.

This patch doesn't try to merge logging macros from different files,
but just unify the debugging code #ifdefs onto a macro on each file. A
further cleanup can unify the debugging macros on a common header, later...

CRIS: Improve ASID related TLB flushes.

  • Speedup and correct ASID (PID) related TLB flushes.
  • Use 64bit tcg load/stores to emulate movem.
  • Remove unused helpers and other minor cleanups.

cf1d97f0 05/13/2008 01:59 pm edgar_igl CRIS: Improve TLB management and handle delayslots at page boundaries.
  • Dont flush the entire qemu tlb when the $pid changes. Instead we go through
    the guests TLB and choose entries that need to be flushed.
  • Add env->dslot and handle delayslots at pageboundaries....

CRIS: Add support for the pseudo randomized set that the mmu provides with TLB refill faults. This makes linux guests use the four way TLB set associativty.

dceaf394 05/07/2008 06:24 pm edgar_igl CRIS: More TCG conversion.
  • Convert moves to/from support function regs (including TLB updates) to TCG.
  • SCC no longer requires T0 to strictly be 0 or 1, relaxed to 0 or non-zero.
  • Convert the the condition code evaluation to TCG.
  • Convert rfe into a helper and TCG....

  • Add support for exec faults and for the k protection bit.
  • Abort if search_pc causes recursive mmu faults.

b41f7df0 05/03/2008 01:16 am edgar_igl CRIS updates:
  • Support both the I and D MMUs and improve the accuracy of the MMU model.
  • Handle the automatic user/kernel stack pointer switching when leaving or entering user mode.
  • Move the CCS evaluation into helper funcs.
  • Make sure user-mode cannot change flags only writeable in kernel mode....

Replace is_user variable with mmu_idx in softmmu core,
allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
and #ifdef TARGET_xxx in softmmu core functions....
