* arm_adi_v5: add/move apsel member in struct adiv5_dapLuca Ellero2011-02-171-57/+50
| | | | | | | | | | | | | | | This patch tries to make some order in "apsel" mess. "dap apsel" command was quite useless (and broken) by itself. With this patch we can use it to select between AHB or APB memory access (previous patch 05ab8bdb813acdcd74afa71d6656c2df816cb230 was somehow broken). - moves member apsel (in struct adiv5_dap) to ap_current - adds apsel member this strange choice is made trying to keep coherence in "dap apsel" command and to keep compatibility with other code (for example cortex_a8).

* fix segfault from stack corruption in ahbap_debugport_initAndreas Fritiofson2011-01-261-5/+4
| | | | | | | | | | | | ahbap_debugport_init was queueing reads to a local stack variable but didn't execute the queue before returning. Since the result of the reads are not used anyway, it's better to pass NULL as the destination instead of a dummy variable. I changed this throughout the function, even for the reads that were actually executed.

* initial SWD transport (SWD infrastructure #2)David Brownell2010-12-241-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This piggy backs on JTAG so it's not yet pretty, but that seems unavoidable so far given today's OpenOCD internals. SWD init and data transfer are unfinished and untested, but that should cause no regressions, and will be addressed by the time drivers start using this infrastructure. Checking in whould get the code working better sooner, and turn up any structural/architectural issues while they're easier to fix. The debug adapter drivers will provide simple SWD driver structs with methods that kick in as needed (instead of JTAG). So far just one adapter driver has been updated (not yet ready to use or circulate). The biggest issues are probably - fault handling, where the ARM Debug Interface V5 pipelining needs work in both JTAG and SWD modes and - missing rewrite of block I/O code to work on both of our Cortex-ready transports (Current code is hard-wired to JTAG); relates also to the pipelining issue. - omitted support to activate/deactivate SWO/SWV trace (this is technically trivial, but configuring what to trace is NOT.

* ADIv5: Introduce function to detect ROM Table locationMarek Vasut2010-11-051-26/+53
| | | | | | | | | | | This patch adds function called "dap_detect_debug_base()", which should be called to get location of the ROM Table. By walking ROM Table, it's possible to discover the location of DAP. Sadly, some CPUs misreport this value, therefore I had to introduce an fixup table, which will be used in case such CPU is detected. Signed-off-by: Marek Vasut <marek.vasut@gmail.com>

* remove more duplicationDavid Brownell2010-03-181-25/+0
| | | | | | | | Not sure how the original "move code to adi_v5_swd.c" patch left some code in the "arm_adi_v5.c" file, but a recent patch was only a partial fix -- it didn't remove all the duplication. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ADIv5 transport support moves to separate filesDavid Brownell2010-03-161-423/+11
| | | | | | | | | | | | | | | | | | | Unclutter arm_adi_v5.c by moving most transport-specific code to a transport-specific files adi_v5_{jtag,swd}.c ... it's not a full cleanup, because of some issues which need to be addressed as part of SWD support (along with implementing the DAP operations on top of SWD transport): - The mess where mem_ap_read_buf_u32() is currently coded to know about JTAG scan chains, and thus needs rewriting before it will work with SWD; - Initialization is still JTAG-specific Also move JTAG_{DP,ACK}_* constants from adi_v5.h to the JTAG file; no other code should care about those values.

* jtag: retire tap fieldØyvind Harboe2010-03-081-5/+2
| | | | | | | | | | | | | | | | | jtag_add_dr/ir_scan() now takes the tap as the first argument, rather than for each of the fields passed in. The code never exercised the path where there was more than one tap being scanned, who knows if it even worked. This simplifies the implementation and reduces clutter in the calling code. use jtag_add_ir/dr_plain_scan() for more fancy situations. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* ADIv5 share DAP command supportDavid Brownell2010-03-051-23/+116
| | | | | | | | | | | | | | Get rid of needless and undesirable code duplication for all the DAP commands (resolving a FIXME) ... there's no need for coreas to have private copies of that stuff. Stick a pointer to the DAP in "struct arm", letting common code get to it. Also rename the "swjdp_info" symbol; just call it "dap". This is an overall code shrink. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* rename "swjdp_common" as "adiv5_dap"David Brownell2010-03-041-32/+32
| | | | | | | | | | | | | This partially corrects an inappropriate name choice (and its associated FIXME). There are still too many variables named "swjdp", bug little current code actually relies on them referencing an SWJ-DP instead of some other flavor of DAP. Only the two new dap_to{swd,jtag}() calls could behave differently on an SWJ-DP instead of a SW-DP or a JTAG-DP. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ADIv5: use new DAP ops for AP read/writeDavid Brownell2010-03-021-98/+67
| | | | | | | | | | | | | | | | | | | Make ADIv5 internals use the two new transport-neutral calls for reading and writing DP registers; and do the same for external callers. Also, bugfix some of their call sites to handle the fault returns, instead of ignoring them. Remove most of the JTAG-specific calls, using their code as the bodies of the JTAG-specific implementation for the new methods. NOTE that there's a remaining issue: mem_ap_read_buf_u32() makes calls which are JTAG-specific. A later patch will need to remove those, so JTAG-specific operations can be removed from this file, and so that SWD support will be able to properly drop in as just a transport layer to the ADIv5 infrastructure. (The way read results are posted may need some more attention in the transport-neutrality interface.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | Make ADIv5 use one of the new transport-neutral interfaces: call dap_run(), not jtagdp_transaction_endcheck().

* ARM: start abstracting ADIv5 transports (JTAG/SWD)David Brownell2010-03-021-0/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | To support both JTAG and SWD, ADIv5 needs DAP operations which are transport-neutral, instead being of JTAG-specific. This patch: - Defines such a transport-neutral interface, abstracting access to DP and AP registers through a conceptual queue of operations. - Builds the first implementation of such a transport with the existing JTAG-specific code. In contrast to the current JTAG-only interface, the interface adds support for two previously-missing (and unused) DAP operations: - aborting the current AP transaction (untested); - reading the IDCODE register (tested) ... required for SWD init. The choice of transports may be fixed at the chip, board, or JTAG/SWD adapter level. Or if all the relevant hardware supports both transport options, the choice may be made at runtime, This patch provides basic infrastructure to support whichever choice is made. The current "JTAG-only" transport choice policy will necessarily continue for now, until SWD support becomes available in OpenOCD. Later patches start phasing out JTAG-specific calls in favor of transport-neutral calls. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ADIv5: use right ID for Cortex-M3 ETMDavid Brownell2010-03-021-4/+4
| | | | | | | | | Correct a mistake made copying the ID of the Cortex-M3 ETM module from the TRM, so that "dap info" on a CM3 with an ETM will now correctly describe ROM table entries for such modules. (They are included on LPC17xx and some other cores.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
