* 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.)

* Subject: flash fill[bwh] should use bulk i/oDavid Brownell2009-12-181-2/+4
| | | | | | | | | It's currently allocating a big buffer but writing it out in units of sizeof(host's pointer) ... sub-optimal. Plus fix a couple minor coding style goofs. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* stellaris: fix min buffer length checksDavid Brownell2009-12-181-7/+4
| | | | | | | Word count == size/4; cope. And increase buf_min so it's large enough to cover the overhead in my tests. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* XScale: better {read,write}_phys()David Brownell2009-12-181-2/+14
| | | | | | | | We can actually do the right thing if the MMU is off; save the error message for the phys-but-MMU-enabled path, which is what isn't yet supported. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* 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. This includes some new updates to introduce more error checking to existing code. [dbrownell@users.sourceforge.net: fix fault handling, whitespace] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* 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).

* JTAG: shrink "scan_chain" outputDavid Brownell2009-12-161-8/+8
| | | | | | | | | | Tweak the "scan_chain" output by removing column separators. Also remove the "current instruction" state ... which changes constantly. Now its style resembles the "targets" output, and can even fit on one line in standard terminals and in the PDF docs. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* stellaris: commentsDavid Brownell2009-12-162-12/+34
| | | | | | | | | | | 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>

* server: server loop will exhaust data inputs before sleepingØyvind Harboe2009-12-161-17/+31
| | | | | | | | | | By exhausting data on input, the performance will be more consistent + the code more clearly distinguishes between polling and processing.

* ARM11: improved reset supportDavid Brownell2009-12-141-48/+55
| | | | | | | | | | | | | | Teach ARM11 how to use: - the new "reset-assert" event - vector catch to implement "reset halt" - use SRST more like other cores do - ... including leaving post-SRST delays up to config scripts This gives OMAP2420 the ability to reset, and doesn't seem to cause new iMX31 problems.

* 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>
* jtag: add '-ignore-version' optionDavid Brownell2009-12-143-6/+38
| | | | | | | | | | Add a "-ignore-version" to "jtag newtap" which makes the IDCODE comparison logic optionally ignore version differences. Update the "scan_chain" command to illustrate this by showing the "*" character instead of the (ignored) version nibble. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target files shouldn't #include <target/...h>David Brownell2009-12-1325-39/+38
| | | | | | | | | | | Make these ".h" files adopt the same policy the ".c" files already follow: don't use <subsystem/...h> syntax for private interfaces. If we ever get reviewed/supported "public" interfaces they should come exclusively from some include/... directory; that'll be the time to switch to <...> syntax for any subsystem's own interfaces. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: further shrink Jim-awarenessDavid Brownell2009-12-134-7/+10
| | | | | | | | | | | | | Don't include <helper/jim.h> from target.h ... not everything which touches targets needs to be able to talk to Jim. Plus, most files include this header by another path. Also, switch the affected files to use the classic sequence for #included files: all <framework/headers.h> first, then the "local_headers.h". This helps prevent growth of problematic layering, by minimizing entanglement. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ARM DPM: support updating HW breakpointsDavid Brownell2009-12-112-52/+75
| | | | | | | | | | | Abstract the DPM breakpoint and watchpoint data structures to have a shared core for housekeeping.

* ARM11: minor cleanup, mostly ITR commentsDavid Brownell2009-12-112-28/+43
| | | | | | | | | | | | | ITR register handling seemed to be giving me problems, so I updated the comments to better say what the code is trying to do ... and to note the preconditions (one of which seems to be an issue) as listed in the ARM1136 TRM. Also removed the unused "ARM11_TAP_DEFAULT" from the ITR scan code; all the callers already specify an exit path, since this register isn't usable with such vague semantics.
