* target: make "examined" flag be per-targetDavid Brownell2009-11-151-13/+6
| | | | | | | | | | | | | | | | | | Previously this flag was stored in "target_type", so that for example if there were two ARM7TDMI targets in a scan chain, both would claim to have been examined although only the first one actually had its examine() method called. Move this state to where it should have been in the first place, and hide a method that didn't need exposure ... the flag is write-once. Provide some doxygen. The examine() method is confusing, since it isn't separating one-time setup from the after-each-reset stuff. And the ARM7/ARM9 version is, somewhat undesirably, not leaving the debug state alone after reset ... probably more of an issue for trace setup than for watchpoints and breakpoints.

* Invalid command syntax errors with MWW.Dean Glazeski2009-11-141-1/+2
| | | | | This fixes an issue due to the new command handler syntax caused by the mw handler playing with the args pointer before using the CMD_NAME macro. Fix is to move this call above the lines changing args.

* add CMD_NAME macro for command handlersZachary T Welch2009-11-131-3/+3
| | | | | By introducing the CMD_NAME macro, this parameter may be integrated as args[-1] in command.[ch], without touching any other call sites.
* use CALL_COMMAND_HANDLER instead of direct callsZachary T Welch2009-11-131-5/+5
| | | | | | By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or even removed in inherited signatures, without requiring revisiting all of the various call sites.

| | | | | Define the numerous helpers that inherit command handler parameters using the COMMAND_HELPER macro.

* add const keyword to some APIsZachary T Welch2009-11-111-1/+1
| | | | | | Add 'const' keyword to 'char *' parameters to allow command handlers to pass constant string arguments. These changes allow the 'args' command handler to be changed to 'const' in a subsequent patch.
* target: MMU-aware init for memory read/writeDavid Brownell2009-11-101-23/+42
| | | | | | | | | | | | | | | | | | Start switching MMU handling over to a more sensible scheme. Having an mmu() method enables MMU-aware behaviors. Not having one kicks in simpler ones, with no distinction between virtual and physical addresses. Currently only a handful of targets have methods to read/write physical memory: just arm720, arm920, and arm926. They should all initialize OK now, but the arm*20 parts don't do the "extra" stuff arm926 does (which should arguably be target-generic). Also simplify how target_init() loops over all targets by making it be a normal "for" loop, instead of scattering its three parts to the four winds.

* Target: minor cleanupDavid Brownell2009-11-101-9/+21

* target.c: remove useless declarationsZachary T Welch2009-11-091-103/+127
| | | | | This patch removes the last batch of forward references from the tree, moving the target command registration routines to the end of the file.
* Revert "target: add target->type->has_mmu fn"David Brownell2009-11-091-33/+5
| | | | | | | | | | | | | | | | This patch introduced a bug preventing flash writes from working on Cortex-M3 targets like the STM32. Moreover, it's the wrong approach for handling no-MMU targets. The right way to handle no-MMU targets is to provide accessors for physical addresses, and use them everywhere; and any code which tries to work with virtual-to-physical mappings should use a identity mapping (which can be defaulted). And ... we can tell if a target has an MMU by seeing if it's got an mmu() method. No such methood means no MMU. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* finish removing deprecated/obsolete commandsDavid Brownell2009-11-091-4/+4
| | | | | | | | | | | | | | | | | | | | It's been about a year since these were deprecated and, in most cases, removed. There's no point in carrying that documentation, or backwards compatibility for "jtag_device" and "jtag_speed", around forever. (Or a few remnants of obsolete code...) Removed a few obsolete uses of "jtag_speed": - The Calao stuff hasn't worked since July 2008. (Those Atmel targets need to work with a 32KHz core clock after reset until board-specific init-reset code sets up the PLL and enables a faster JTAg clock.) - Parport speed controls don't actually work (tops out at about 1 MHz on typical HW). - In general, speed controls need to live in board.cfg files (or sometimes target.cfg files), not interface.cfg ...

* Overhaul time support APIZachary T Welch2009-11-091-53/+30
| | | | | | | | | | | | | | | | | | | This patch changes the duration_* API in several ways. First, it updates the API to use better names. Second, string formatting has been removed from the API (with its associated malloc). Finally, a new function added to convert the time into seconds, which can be used (or formatted) by the caller. This eliminates hidden calls to malloc that require associated calls to free(). This patch also removes the useless extern keyword from prototypes, and it eliminates the duration_t typedef (use 'struct duration'). These API also allows proper error checking, as it is possible for gettimeofday to fail in certain circumstances. The consumers have all been chased to use this new API as well, as there were relatively few cases doing this type of measurement. In most cases, the code performs additional checks for errors, but the calling code looks much cleaner in every case.
* target: don't swap MMU/no-MMU work areasDavid Brownell2009-11-061-16/+17
| | | | | | | | | | | | | | | Resolve serious bug inserted by the "target: require working area for physical/virtual addresses to be specified" patch. It forced use of (invalid) virtual addresses when the MMU was disabled, and vice versa. Observed to break at least Cortex-M3, ARM926, ARM7TDMI whenever work areas are used, such as during bulk writes to flash, DDR2, SRAM, and so on. Also, fix overlong lines and whitespace goofs.

* target: require working area for physical/virtual addresses to be specifiedØyvind Harboe2009-11-031-6/+24
| | | | | | | | | | | | | | | | Fixed bug: if virtual address for working memory was not specified and MMU was enabled, then address 0 would be used. Require working address to be specified for both MMU enabled and disabled case. For some completely inexplicable reason this fixes the regression in svn 2646 for flash write in arm926ejs target.
