- 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.

Remove broken whitespace ... mostly at end of line, but
also in some cases blocks of inappropriate empty lines.
And spell "comamnd" right. :)

- replaces all calls to target->type->run_algorithm.
- add documentation in target_s to warn not to invoke callback directly.
git-svn-id: svn://svn.berlios.de/openocd/trunk@1961 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- cleaned up headers to match rest of code
- added missing svn props for previously added files
git-svn-id: svn://svn.berlios.de/openocd/trunk@987 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- DCRDR now used to access special core registers - info is currently omitted from the cortex_m3 TRM ARM have told me this is the preferred access method and the docs will be updated soon.
- now checks for User Thread Mode and Thread mode when halted.
- removed repeated function declarations from command.c
- cortex_m3_prepare_reset_halt removed, updated cortex_m3_assert_reset to suit

uninitialized buffer issue in handle_flash_info_command in flash.c, some formatting.

Small cosmetic fixes in the license header to make them all look the
same, fix some typos, update README.

command and reduce confusion with "flash write_image".
- retired deprecated "flash erase" & "flash write".
- added flash_driver_protect/write/erase() that are wafer thin frontend
functions to low level driver functions. They implement checks
that were inconsistently handled by the drivers, e.g. check for
target halted was done in a spotty fashion.
- use return ERROR_COMMAND_SYNTAX_ERROR to print out
syntax of command instead of having lots of inlined replicas of
the command line syntax(some of which were wrong).
- use logging instead of dubious translation of error values to
human understandable explanations of why things failed.
The lower levels log the precise reason and the higher
levels can ammend context as the error propagates up
the call stack.
- simplified flash API slightly with logging instead of
allocating and returning information that the caller then
has to translate into print statements.

- corrected blocksize handling from GDB "info mem" command
(thanks to Øyvind and Spen for these patches)
git-svn-id: svn://svn.berlios.de/openocd/trunk@278 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- Clean up, remove unused variables and code in armv7, cortex_m3 and stellaris code
- Move restore_context from cortex_m3 to armv7m
- Updated halt handling for cortex_m3
git-svn-id: svn://svn.berlios.de/openocd/trunk@206 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- make ep93xx and at91rm9200 bitbang JTAG interfaces dependant on ARM host (thanks to Vincent Palatin)
- various whitespace fixes
- removed various warnings
- add support for Debian GNU/kFreeBSD (thanks to Uwe Hermann)
- fix OpenOCD compilation for various platforms (thanks to Uwe Hermann and Vincent Palatin)
- switched order of JTAG chain examination and validation (examine first, then multiple validation tries even if examination failed)
- added target_request subsystem to handle requests from the target (debug messages and tracepoints implemented, future enhancements might include
semihosting, all ARM7/9 only for now)
- added support for GDB vFlashXXX packets (thanks to Pavel Chromy)
- added support for receiving data via ARM7/9 DCC
- reworked flash writing. the 'flash write' command is now deprecated and replaced by 'flash write_binary' (old syntax and behaviour) and 'flash
write_image' (write image files (bin, hex, elf, s19) to a target).
- added support for AMD/ST/SST 29F400B non-cfi flashes
