2013-10-15arm7_9: Avoid infinite loops in bulk write dispatchingAndreas Fritiofson
Add a mandatory field in struct arm7_9_common for regular, non-optimized memory writes. Together with the existing bulk_memory_write field, this allows variants to select any combination of implementations for regular and bulk writes, without risking infinite loops from accidentally using bulk writes for implementing bulk writes. ARM 7/9 targets may now select arm7_9_memory_write_opt as their target.write_memory implementation, which will dispatch to arm7_9_common.bulk_write_memory if possible, or fallback to arm7_9_common.write_memory otherwise. To avoid loops, bulk write implementations mustn't call any other functions than arm7_9_write_memory_no_opt() to write memory; it will unconditionally call arm7_9_common.write_memory. If they fail, they should simply return error to allow the caller to fallback to regular writes. Tested on a regular ARM7TDMI only.

2013-09-13[RFC] target: Move bulk_write_memory to arm7_9Andreas Fritiofson
The only remaining user is arm7_9 so remove it from the target API and add it to struct arm7_9_common to support all its variants with minimal changes. Many of the variants are likely not correct in the cache/mmu handling when the bulk write is triggered. This patch does nothing to change that, except for arm946e, where it was easier to do what might be the right thing.

2009-12-13target files shouldn't #include <target/...h>David Brownell
Make these ".h" files adopt the same policy the ".c" files already follow: don't use <subsystem/...h> syntax for private interfaces. If we ever get reviewed/supported "public" interfaces they should come exclusively from some include/... directory; that'll be the time to switch to <...> syntax for any subsystem's own interfaces.

2009-11-05ARM: shrink offsetsDavid Brownell
Move various embedded target structs to the beginnings of their containers ... pretty much the way C++ or Obj-C would for single inheritance. This shrinks code that accesses those embedded structs by letting common offsets use smaller instructions. Sample before/after sizes (on amd64): 17181 312 0 17493 4455 arm920t.o 16810 312 0 17122 42e2 arm920t.o Where the "after" is the smaller number, with this patch over the ones leveraging that embedding knowledge.

2009-11-05target: provide container_of()David Brownell
Provide a cleaner way to handle single inheritance of targets in C, using the same model Linux does: structs containing other structs, un-nested via calls to a "container_of()" macro that are packaged in typesafe inline functions. Targets already use this containment idiom, but make it much more complicated because they un-nest using embedded "void *" pointers ... in chains of up to five per target, which is all pure needless complication. (Example: arm92x core, arm9tdmi, arm7_9, armv4_5 ... on top of the base "target" class.) Applying this scheme consistently simplifies things, and gets rid of many error-prone untyped pointers. It won't change any part of the type model though -- it just simplifies things. (And facilitates more cleanup later on.) Rule of thumb: where there's an X->arch_info void* pointer, access to that pointer can and should be removed. It may be convenient to set up pointers to some of the embedded structs; and shrink their current "*_common" names (annoyingly long). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-11-05ARM920: remove exports and forward declsDavid Brownell
Unneeded exports cause confusion about the module interfaces. Make most functions static. Add a short header comment. The forward decls are just code clutter; remove them, by moving their references after definitions. This is another file which never needed even one internal forward declaration. This saved almost 900 bytes of code on x86_32; it seems the compiler can leverage its knowledge that these functions are not called from the outside world...
