flash driver:
- Bugfixes:
* internal osc: it's *12* MHz (not 15 MHz) on _current_ chips
+ except new Tempest parts where it's 16 MHz (and calibrated!)
+ or some old Sandstorm ones, where 15 MHz was valid
* crystal config:
+ read and use the crystal config, don't assume 6 MHz
+ know when that field is 4 bits vs 5
* an RCC2 register may be overriding the original RCC
+ more clock source options
+ bigger dividers
+ fractional dividers on Tempest (NYET handled)
* there's a 30 KHz osc on newer chips (for deep sleep)
* there's a 32768 Hz osc on newer chips (for hibernation)
- Cosmetic
* say "rev A0" not "vA.0", to match vendor docs
* don't always report master clock as an "estimate":
+ give the error bound if it's approximate, like "±30%"
+ else don't say anything
* fix whitespace and caps in some messages
* these are not AT91SAM chips!!
Those clock issues might explain problems sometimes reported when
writing to Stellaris flash banks; they affect write timings.
That 12-vs-15 MHz issue is problematic; there's no consolidated doc
showing which chips (and revs!) have which internal oscillator speed.
It's clear that only older silicon had the faster-and-less-accurate
flavor. What's less clear is which chips are "old" like that.
Lightly tested, on a DustDevil part.

For ARMv4/ARMv5:
- better command parameter error checking
- don't require an instruction count; default to one
- recognize thumb function addresses
- make function static
- shorten some too-long lines
For Cortex-M3:
- don't require an instruction count; default to one
With the relevant doc updates.

Nyet done: invoke the thumb2 disassembler on v4/v5,
to better handle branch instructions.

Unify the handling of the req_srst parameter, and rip out a
large NOP branch and its associated FIXME. (There didn't seem
to be anything that needs fixing; but that was unclear since
the constraints were scattered all over the place not unified.)

Unify the handling of the req_tlr_or_trst parameter. Basically,
JTAG TMS+TCK ops ("TLR") is always used ... unless TRST is a safe
option in this system configuration.

- Track whether TRST and/or SRST actually change:
* If they're not changing, don't ask the JTAG adapter to do anything!
(JTAG TCK/TMS ops might still be used to enter TAP_RESET though.)
* Don't change their recorded values until after the adapter says it
did so ... so fault paths can't leave corrupt state.
* Detect and report jtag_execute_queue() failure mode
* Only emit messages saying what really changed; this includes adding
an omitted "deasserted TRST" message.
* Only apply delays after deasserting SRST/TRST if we *DID* deassert!
- Messages say "TLR" not "RESET", to be less confusing; there are many
kinds of reset. (Though "TLR" isn't quite ideal either, since it's
the name of the TAP state being entered by TMS+TCK or TRST; it's at
least non-ambiguous in context.)
So the main effect is to do only the work this routine was told to do;
and to have debug messaging make more sense.

various target-specific
reset operations. Maybe they can't; or it's a "not yet" thing.
Note that the assert/deassert operations can't yet trigger for
OMAP3 because resets currently include JTAG reset in all cases,
resetting the ICEpick and thus disabling the TAP for Cortex-A8.

previous
nonfunctional cortex_a8 code with something that at least basically
works (for halt/step/resume, without MMU) even if it is incomplete.
(With tweaks from Øyvind, and cleanup from Dave.)
This code has mainly been developed and tested against R1606, it has
been built and tested against R2294 where it runs but step and resume
commands are broken due to regression (which should be fixed now).
This code is really written for OMAP3530. It doesn't identify debug
resources using generic DAP calls to scan the ROM table, or perform
topology detection. The OMAP3530 DAP exposes two memory access ports:
- Port #0 is connected to L3 interconnect (the main bus) with
passthrough to the L4 EMU bus ... so it will be used for most
memory accesses.
- Port #1 is connected to a dedicated debug bus (L4 EMU), with
access to L4 Wakeup, and holds the ROM table ... so it must
be used for most debug and control operations.
The are some defines to handle this in cortex_a8.c, which should be
replaced with more general code. Having access to another Cortex-A8
implementation would help get that right.

and seed it with DAP access support using the current ADIv5 code.
(With tweaks and cleanup from Øyvind and Dave.)
The ARMv7-AR architecture manual is not publicly available (even
in subset form like the ARMv7-M spec), so it's hard to distinguish
between the Cortex-A8 implementation and the ARMv7-A architecture.
The register set presumably is architectural, and so it's stored
here; it's like earlier ARMs, with small additions. Ditto the
instruction set, though Thumb2 support is used (extending Thumb
support from ARMv6 with more 32-bit instructions) and there's this
ThumbEE thing too. There is a new "debug monitor" mode, not yet
fully addressed here, to support debugging in environments (like
motor control) where halting debug mode is inadvisable.

ARMv7-M: A5.3.6 Load/store dual or exclusive, table branch
GCC will generate the table branch instructions, usually with inlined
tables that will confuse this disassembler. LDREX and STREX are not
issued by GCC without inline assembly.
This means all Thumb2 instructions implemented by Cortex-M3 can now
be disassembled. Cortex-A8 cores support more Thumb2 instructions,
but most of those aren't yet publicly documented.

- AIRCR_SYSRESETREQ is generic; use it on any system where
SRST won't fly, not just on Stellaris-based ones.
- Reformat and improve comments about the Stellaris quirk; and
xref the only public docs (an email) about the issue.
It seems that *most* Stellaris chips have this problem. Tempest
parts aren't yet in general sampling; and if rev B silicon for
earlier chips exists, it's not very visible yet.

Simplify dumping of register lists by only printing cached values
if they are marked as valid. Most of the time, they are invalid;
so printing *any* value is just misleading.
Note that for ARM7 and ARM9 most EmbeddedICE registers (except for
debug status) could be cached most of the time; and their register
cache isn't maintained properly (many accesses seem to bypass that
cache code).

1. It can only be built with the FTD2XX driver. libftdi supports FT2232H/FT4232H
since version 0.16
2. A speed value of 0 is used as a RTCK request indicator. This clashes with the
valid clock division value 0 that provide the highest fixed clock frequency.
3. The ft2232_speed_div function return the maximum selectable frequency (30MHz)
when RTCK is activated. It should return 0.
4. The ft2232_khz function return ERROR_OK when RTCK is requested even for
devices lacking RTCK support. It should return ERROR_FAIL so the upper driver layers
can detect this and try to fallback to a fixed frequency.
5. FT2232H/FT4232H have a backward compatibility function that divide the clock
by 5 to get the same frequency range as FT2232D. There is no code that disable
this functionality. I can not find anything about if this is enabled or disabled by default.
I think it is safest to actively disable it.

* flash config uses $_TARGETNAME (it might not be target #0)
* simplify one $_TARGETNAME construction
- update work area setup:
* remove VM spec; these chips have no VM!
* fix some wrong sizes (0x4000 == 16K, not 4K)
* simplify: take defaults

and docs. One minor
issue with this is that the core debug support uses this
mechanism, then trashes its state over reset. Users can
Work around that (for now) by re-assigning the desired
config after reset.
Also fixes "target halted due to target-not-halted" goof.
When we can't describe the reason using OpenOCD's limited
vocabulary, say "reason undefined" instead of saying it's
not halted.

handling ... don't use parallel
arrays (error prone) or assume all registers are 32-bits wide (they can
have fewer bits); don't use spaces in register names, so they can be
passed more easily to the "reg" command.
Minor updates for ARM9 vector_catch support: it's an 8-bit value. This
seems to help this core's vector_catch command work a bit better; but its
behavior wih the register cache is still goofy.
