ARM: new DPM interface
First version of interface for sharing code between ARMv6 and ARMv7a
debug modules ... now the architecture includes debug support. (Not
the same as for the trimmed-down v7m or v6m though!) This is a first
version of an interface that will let the ARM11 and Cortex-A8 support
share code, features, and bugfixes. Based on existing code from both
of those cores.
The ARM v7-AR architecture specification calls this commonality the
"Debug Programmer's Model (DPM)", which seemed to be an appropriate
acronym -- a TLA even! -- for use in our code. Made it so. :)
The initial scope of this just supports register access, and is geared
towards supporting top level "struct arm" mechanisms. Later, things
like breakpoint and watchpoint support should be included.
