* | target: don't swap MMU/no-MMU work areasDavid Brownell2009-11-061-16/+17
|/ | | | | | | | | | | | | | | Resolve serious bug inserted by the "target: require working area for physical/virtual addresses to be specified" patch. It forced use of (invalid) virtual addresses when the MMU was disabled, and vice versa. Observed to break at least Cortex-M3, ARM926, ARM7TDMI whenever work areas are used, such as during bulk writes to flash, DDR2, SRAM, and so on. Also, fix overlong lines and whitespace goofs.

* ARM: shrink offsetsDavid Brownell2009-11-056-8/+8
| | | | | | | | | | | | | | | | | | 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.

* Cortex-M3: use the new inheritance/nesting schemeDavid Brownell2009-11-054-135/+113
| | | | | | | | | | | | Use new target_to_cm3() and target_to_armv7m() inlines, instead of a series of x->arch_info conversions. Remove arch_info, since nothing uses it. Also fix an omission: the Cortex-M3 commands didn't verify that they were operating on that kind of target. Add comment about the ARMv7M version of that omission.

* target: provide container_of()David Brownell2009-11-0512-0/+91
| | | | | | | | | | | | | | | | | | | | | | | | | 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>
* ARM7TDMI: remove forward declsDavid Brownell2009-11-052-92/+88
| | | | | | | | | | | | 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. Also shrink a few overly-long lines with function declarations or definitions; get rid of arm7tdmi_register_commands(), it's not needed (just delegated); minor whitespace declutter.

* ARM720: remove exports and forward declsDavid Brownell2009-11-051-119/+95
| | | | | | | | | | | | | | Unneeded exports cause confusion about the module interfaces. Make all 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. Remove unneeded indirection for the write_memory() method. Make a table static, remove a can't-happen case with nasty exit(). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | | | | | | | Unneeded exports cause confusion about the module interfaces. Make most functions static. 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. Also remove needless arm966e_init_target(), in favor of the arm9tdmi routine to which it delegates its work. This saved over 100 bytes of code on x86_32.

* ARM926: more cleanupDavid Brownell2009-11-051-37/+22
| | | | | | | | | | | | An init_target() wrapper isn't needed, and target_create() can shrink a bit. Add a header comment and some doxygen. Remove arm926ejs_catch_broken_irscan() which has been a NOP for quite a few months now, and in any case duplicates logic in the JTAG core to validate IR capture data. But force the capture mask to 0x0f, so those tests are most effective. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM920: remove exports and forward declsDavid Brownell2009-11-052-112/+150
| | | | | | | | | | | | | | | 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...

* watchpoint_add() cleanupDavid Brownell2009-11-054-32/+40
| | | | | | | | | | | | Fail watchpoint_add() if it's the same address but the parameters are different ... don't just assume having the same address means the same watchpoint!

* Cortex-M3: expose most DWT registersDavid Brownell2009-11-052-21/+144
| | | | | | | | | | | | | | | | | | | | | | | Expose most DWT registers via Tcl; there are a few more, but those are mostly for profiling along with the ITM. Having this set available enables operations which aren't possible with just the standard watchpoint operations. The cycle counter may be interesting. Turn it on after reset by setting the LSB of the dwt_ctrl register, and it counts CPU clocks. You can program the comparator 0 watchpoint to trigger on a given cycle count, rather than a data address. Likewise, comparator 1 may be able to match data values given address matches from one or two other comparators. (Not all hardware supports this capability though; try it. That is something the standard watchpoint methods should eventually handle, for the single address case.) Minor cleanup: remove needless functional indirection for exposing the v7m architctural registers. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
