* ARM: ADIv5 export cleanupDavid Brownell2010-01-022-31/+35
| | | | | | | | | Make some private functions "static". Remove their public declarations, and what is now an obviously unused function. Shrinks this object's size (about 5% on x86_64) while making the code's scope easier to understand. Shrink the affected lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: ADIv5 symbol and comment cleanupDavid Brownell2010-01-022-29/+94
| | | | | | | | | | | Instead of magic numbers, use their AP_REG_* constants. Rename the ROM address symbol as BASE to match ARM's documentation. Comment various other symbols in the header; add some missing ones. Remove an unused struct. Add some doxygen for stuff including the DAP structure and initialization.

* streamline and document helptext mode displaysDavid Brownell2010-01-027-16/+29
| | | | | | | | | | | | | | | | | | | Most commands are usable only at runtime; so don't bother saying that, it's noise. Moreover, tokens like EXEC are cryptic. Be more clear: highlight only the commands which may (also) be used during the config stage, thus matching the docs more closely. There are - Configuration commands (per documentation) - And also some commands that valid at *any* time. Update the docs to note that "help" now shows this mode info. This also highlighted a few mistakes in command configuration, mostly commands listed as "valid at any time" which shouldn't have been. This just fixes ones I noted when sanity testing.

* Fix usage/help search for subcommands.Dean Glazeski2010-01-021-7/+34
| | | | | | | | This makes it so that the usage/help command properly uses the whole command, including subcommand, in the search for help information. This previously caused erroneous output from the usage command handler. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Add the current command to the command informationDean Glazeski2010-01-021-0/+1
| | | | | | | | | | | I wanted to make it so I can be ignorant of a commands invocation string, so I tried to use CMD_CURRENT (aka cmd->current) which is supposed to house a pointer to the current command.  It turns out that this wasn't being set. This patch adds the current command structure to the command invocation structure before sending it along to the command handler. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* Fix Luminary FT2232 layout docs/configsDavid Brownell2009-12-281-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of this patch updates documentation and comments for various Luminary boards, supporting two bug fixes by helping to make sense of the current mess: - Recent rev C lm3s811 eval boards didn't work. They must use the ICDI layout, which sets up some signals that the older boards didn't need. This is actually safe and appropriate for *all* recent boards ... so just make "luminary.cfg" use the ICDI layout. - "luminary-lm3s811.cfg", was previously unusable! No VID/PID; and the wrong vendor string. Make it work, but reserve it for older boards where the ICDI layout is wrong. - Default the LM3748 eval board to "luminary.cfg", like the other boards. If someone uses an external JTAG adapter, all boards will use the same workaround (override that default). The difference between the two FT2232 layouts is that eventually the EVB layout will fail cleanly when asked to enable SWO trace, but the ICDI layout will as cleanly be able to enable it. Folk using "luminary.cfg" with Rev B boards won't see anything going wrong until SWO support is (someday) added. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NOR: last_addr also needs correction when checking alignmentPiotr Esden-Tempski2009-12-281-0/+1
| | | | | | | Otherwise the new alignment checking algorithm thinks that the address is not aligned, because it is way beyond the last sector. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NOR: make flash_write_unlock() pad to sector endDavid Brownell2009-12-271-2/+42
| | | | | | | | | | | | | | Resolve a regression when using newish automagic "write_image" modes, by always padding to the end of affected sectors. Also document some issues associated with those automagic options, in the User's Guide and also some related code comments. We might need similar padding at the *beginning* of some sectors, but this is a minimalist fix for the problems which have currently been reported (plus doc updates).

* cygwin 1.7 build fixesDavid Brownell2009-12-266-14/+16
| | | | | | | | | | | It's less accepting of signed char ... insisting that e.g. tolower() not receive one as a parameter. It's probably good to phase out such usage, given the number of bugs that lurk in the vicinity (assumptions that char is unsigned), so fix these even though such usage is actually legal.

* AT91SAM9 NAND flash driver.Dean Glazeski2009-12-193-1/+754
| | | | | | | | | | This creates the TCL interface for configuring an AT91SAM9 NAND flash controller and implements the necessary functions to correctly work with a NAND flash device connected to the chip.

* ETM: add "etm trigger_debug" commandDavid Brownell2009-12-191-4/+62
| | | | | | | | | | | | | | | | In conjunction with manual register setup, this lets the ETM trigger cause entry to debug state. It should make it easier to test and bugfix the ETM code, by enabling non-trace usage and isolating bugs specific to thef ETM support. (One current issue being that trace data collection using the ETB doesn't yet behave.) For example, many ARM9 cores with an ETM should be able to implement four more (simple) breakpoints and two more (simple) watchpoints than the EmbeddedICE supports. Or, they should be able to support complex breakpoints, incorporating ETM sequencer, counters, and/or subroutine entry/exit criteria int criteria used to trigger debug entry.

* ETM: more ETM_CTRL bit cleanupDavid Brownell2009-12-192-56/+49
| | | | | | | | | | | | | | | | | | | Change handling of the CYCLE_ACCURATE, BRANCH_OUTPUT, and TRACE_* flags; also the CONTEXTID size values. - Convert to symbols matching the actual register bits, instead of some random *other* bits (and then correcting that abuse). - Get rid of a now-needless enum. - Keep those values in etm->control, and remove etm->tracemode. These values all affect the trace data that's recorded by a trace pod or in the ETB. I modified the file format used to dump ETB data; since it's fairly clear nobody can use this mechanism now, this can't cause anyone trouble. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ETM: start cleaning up ETM_CTRL bit handlingDavid Brownell2009-12-193-36/+63
| | | | | | | | | | | | | | | | | | | | | Provide better comments for the ETM_CTRL bits; use the correct bit for half/full clock mode; and define a few more of the bits available from the earliest ETM versions. The new bit defintions use ETM_CTRL_* names to match their register (instead of ETM_PORT_* or ETMV1_*). For clarity, and better matching to docs, they are defined with bitshifting not pre-computed masks. Stop abusing typdefs for ETM_CTRL values; such values are not limited to the enumerated set of individual bit values. Rename etm->portmode to etm->control ... and start morphing it into a single generic shadow of ETM_CTRL. Eventually etm->tracemode should vanish, so we can just write etm->control to ETM_CTRL. Restore an "if" that somehow got dropped. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ETM trigger_percent becomes an ETB commandDavid Brownell2009-12-194-52/+58
| | | | | | | | This command was misplaced; it's not generic to all traceport drivers, only the ETB supports this kind of configuration. So move it, and update the relevant documentation. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NOR FLASH: only erase/unlock whole sectorsDavid Brownell2009-12-181-8/+36
| | | | | | | | | | | | | | | Much to my surprise, I observed a "flash erase_address ..." command erasing data which I said should not be erased. The issue turns out to be generic NOR flash code which was silently, and rather dangerously, morphing partial-sector references into unrequested whole-sector ones. This patch removes that low-level morphing. If desired, it can and should be done in higher level code. (We might need to fix some stuff in the GDB server code.)

* stellaris: update bulk flash writesDavid Brownell2009-12-181-20/+45
| | | | | | | | | | | | | | | | | | | | | | | Try to right-size the SRAM buffers, by not: - using them for very small writes - giving up when a large buffer isn't available - allocating buffers much larger than their data Also don't: - bother loading the code unless we allocate the writebuffer too - be so verbose with messaging: * be more concise * reduce importance (e.g. DEBUG not WARNING) * remove duplication The minimum buffer size is something of a guess. It's eight times smaller than before, almost the same size as the code being downloaded. It probably deserves some tuning. Also, note an erratum affecting flash protection on some chips; and narrow many over-wide lines affected by the above changes. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NAND write data page refactoring.Dean Glazeski2009-12-182-59/+69
| | | | | | | | | | | Refactored the write page raw function into two new functions for writing data to a NAND device and then another function to finish up a write to a NAND device.

* NAND read data page refactor.Dean Glazeski2009-12-182-45/+25
| | | | | | | | | | | | | | Added a new function to encapsulate reading a page of data from a NAND device using either the read_block_data function of a NAND controller or to use direct reading of data from the NAND device. This also adds some performance enhancements and uses the read_data function if the read_block_data function fails safely (because it can't allocate a buffer in the working area).

* 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.
