* stellaris: commentsDavid Brownell2009-12-161-0/+21
| | | | | | | | | | | Someday revisit various issues: Tempest parts support writing more than one word at a time; for some target firmware it might be necessary to save and restore flash IRQ configuration. (The safest policy is likely to always reset after flash updates.) Plus swap some undesirable TAB characters with SPACE. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* stellaris: probe() cleanupsDavid Brownell2009-12-161-86/+42
| | | | | | | | | | | | | | Fix potential memory leak: make sure the per-bank data structures are only allocated in probe(), and that calling probe() multiple times is a NOP. Use it for auto_probe(). Require probe() to have done its thing: don't make access routines cope with it not having been called. Shrink a bunch of failure paths; and in some cases, correct them. Don't needlessly insist on a halted target for probe(). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* stellaris: remove needless codeDavid Brownell2009-12-161-50/+1
| | | | | | | No point in reading and discarding a status value when fetching part description data. Or having that needless "#if 0" code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* stellaris: avoid chip writesDavid Brownell2009-12-161-13/+10
| | | | | | | | | | | | Previously "reading" clock info (and part info) also, as a side effect, wrote the flash timing register. Instead, be more safe: "reading" should only read. Write paths still refresh timing, coping with changes the application code may have made. Also rename the routine which sets flash timing, indicating what it's really doing; it's got nothing to do with a "mode". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* stellaris: device IDsEric Wetzel2009-12-141-150/+168
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I added the remaining devices and device IDs to stellaris.c, and removed several devices that don't exist on the Stellaris web page. Additionally, I found a few devices with duplicate IDs ... the DID1 Version Number for LM3Sxxx parts have DID1 Version = 0x0, and for LM3Sxxxx have DID1 Version = 0x1. So I extended the comparison to use the VER and FAM fields from DID1 also. ID=0x33: LM3S812 (DID1v0) and LM3S2616 (DID1v1) ID=0x39: LM3S808 (DID1v0) and LM3S2276 (DID1v1) These are the parts I removed from the file for lack of documentation (no data sheet to confirm part ID): LM3S318, LM3S1101, LM3S1108, LM3S1615, LM3S1616, LM3S2016, LM3S2101, LM3S2108, LM3S3759, LM3S3768, LM3S5757, LM3S5767, LM3S5768, LM3S5769, LM3S6815, LM3S6816, LM3S6915, LM3S6916, LM3S6111, LM3S6118. Also, sort devices according to part number. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* stellaris: flash protection updates, minor fixesDavid Brownell2009-12-091-67/+109
| | | | | | | | | | | | | | | | | | | | | | | | | Bugfix the read side of flash protection: - read the right register(s)! - handle more than 64K - record the results in the right places - don't display garbage. Partially bugfix the write side: - use 2KB lock regions instead of 1KB pages (!) - validate input range - don't try to _remove_ protection (it's write-once) - #define values we'll need to commit writes. - ... still doesn't handle pages over 64KB mark, or commit writes And minor cleanup and fixes: - get rid of some forward decls - properly locate a doxygen comment - fix some bad indentation - remove superfluous #include - add a new part ID (many are still missing) - make the downloaded algorithm code be read-only Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* remove target.h from flash.hZachary T Welch2009-12-041-1/+2
| | | | | The flash.h header does not require the target.h header file, but its implementation source files do. Move it to flash/nor/imp.h.
* change #include "armv7m.h" to <target/armv7m.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "armv7m.h" the following form should be used. #include <target/armv7m.h> The exception is from .c files in the same directory.
* change #include "algorithm.h" to <target/algorithm.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "algorithm.h" the following form should be used. #include <target/algorithm.h> The exception is from .c files in the same directory.

* move nor drivers to src/flash/norZachary T Welch2009-12-021-0/+1195
Moves NOR flash drivers to 'src/flash/nor/'. Adds 'src/flash/nor/Makefile.am'. Builds 'libocdflashnor.la'.
