* ETM cleanupDavid Brownell2009-11-114-131/+120
| | | | | | | | | | | | | | | | Various cleanups of ETM related code. - Saner error return paths - Simplify arm7_9 init ... no need for extra zeroing! - Shrink some lines - Tweak some diagnostics - Use shorter name for ETM struct type. - Don't exit() and similar. The diagnostics look forward to having this ETM code work with more than just ARM7/ARM9. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ARM720: bugfixDavid Brownell2009-11-101-1/+2
| | | | | | | The "ARM720 uses the new inheritance/nesting scheme" patch wrongly scrubbed a calloc() from arm720t_target_create(). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: MMU-aware init for memory read/writeDavid Brownell2009-11-102-28/+51
| | | | | | | | | | | | | | | | | | 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.cfg: (re)move some bogus reset_config linesDavid Brownell2009-11-105-13/+3
| | | | | | | General rule, this is all board-specific and doesn't belong in target config files. Some of these were just cosmetic. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* stm32.cfg: remove reset_configThomas Kindler2009-11-101-3/+0
| | | | | | | | | | | | | | | Here's a patch for the double-reset problem on STM32. I've tested downloading and debugging with GDB and Eclipse, and everything seems to work fine. This effectively sets reset_config to none. trst_only would also be ok, but that's better left to a board configuration file since not all boards wire it up. The NVIC is used to trigger reset, which at least on this chip also pulses nSRST so the whole system does get rest -- exactly once. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* Revert "target: add target->type->has_mmu fn"David Brownell2009-11-093-48/+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 Brownell2009-11-0913-211/+10
| | | | | | | | | | | | | | | | | | | | 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 Welch2009-11-096-215/+153
| | | | | | | | | | | | | | | | | | | 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.
* Add private header for ARM11 internals.Zachary T Welch2009-11-084-50/+74
| | | | | | | Reduces confusion about location of associated routines and reduces clutter in the arm11 header. Removes extra whitespace around the lines touched by these changes.

* target.cfg: remove "-work-area-virt 0"David Brownell2009-11-0845-46/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semantics of "-work-area-virt 0" (or phys) changed with the patch to require specifying physical or virtrual work area addresses. Specifying zero was previously a NOP. Now it means that address zero is valid. This patch addresses three related issues: - MMU-less processors should never specify work-area-virt; remove those specifications. Such processors include ARM7TDMI, Cortex-M3, and ARM966. - MMU-equipped processors *can* specify work-area-virt... but zero won't be appropriate, except in mischievous contexts (which hide null pointer exceptions). Remove those specs from those processors too. If any of those mappings is valid, someone will need to submit a patch adding it ... along with a comment saying what OS provides the mapping, and in which context. Example, say "works with Linux 2.6.30+, in kernel mode". (Note that ARM Linux doesn't map kernel memory to zero ...) - Clarify docs on that "-virt" and other work area stuff. Seems to me work-area-virt is quite problematic; not every operating system provides such static mappings; if they do, they're not in every MMU context...
