- added "xscale fast_memory_access" which speeds up memory
access by disabling "unecessary" checks. - arm926ejs. Added missing type->mmu and type->virt2phys fn's. for now these are used by working_area when specifying mmu enabled and mmu not enabled address git-svn-id: svn://svn.berlios.de/openocd/trunk@335 b42882b7-edfa-0310-969c-e2dbd0fdcd60
