* jtag: cut down on usage of unintended modification of global end stateØyvind Harboe2010-03-1824-99/+4062
| | | | | | | | | | | | | jtag_get/set_end_state() is now deprecated. There were lots of places in the code where the end state was unintentionally modified. The big Q is whether there were any places where the intention was to modify the end state. 0.5 is a long way off, so we'll get a fair amount of testing.

* ADIv5 transport support moves to separate filesDavid Brownell2010-03-165-430/+589
| | | | | | | | | | | | | | | | | | | 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.

* lpc3180: LPC3180(LPC3250) SLC driver implementedrichard vegh2010-03-162-9/+441
| | | | | | | | | | | | | | | | Until this time only basic SLC functionality exists when you want to use SLC to access external nand flash. Basic functionality can be selected with command: lpc3180 select 0 slc It is anyway very slow to write/read to/from nand flash. With the new command, SLC speed improved about 20 times, and hardware ECC info also read/written from/to nand flash OOB area: lpc3180 select 0 slc bulk Speed improvement achieved by using working are in SRAM of the LPC3250 chip and controlling DMA controller to interact between SRAM and SLC peripheral. Here are the patches, and if they are ok than take them. Tested with hitex LPC3250 usb stick. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* image loading: fix problem with offsets > 0x80000000Bradey Honsinger2010-03-164-4/+4
| | | | | | | | | | | | | | | Fixes bug that prevented users from specifying a base address of 0x80000000 or higher in image commands (flash write_image, etm image, xscale trace_image). image.base_address is an offset from the start address contained in the image file (if there is one), or from 0 (for binary files). As a signed 32-bit int, it couldn't be greater than 0x7fffffff, which is a problem when trying to write a binary file to flash above that address. Changing it to a 64-bit long long keeps it as a signed offset, but allows it to cover the entire 32-bit address space. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

| | | | | | | | | | | | The SRST configuration options are not specific to JTAG, so this command may be needed with non-JTAG debug sessions. Just move the command to a different group. (The TRST options are, however, clearly JTAG-specific, but for compatibility, they're now left alone. The flags they control could later be disabled in non-JTAG sessions.)

* split "interface" commands from "jtag" onesDavid Brownell2010-03-114-5/+31
| | | | | | | | | | | | | | | | | | | | | | | | | We'll need to be able to work with debug adapter interfaces (drivers) even when they're not used for JTAG ... for example, while there are multi-transport drivers which support JTAG *and* several other transports (or just one more, like SWD) there are also adapters with more limited goals (and no JTAG support at all). Start decoupling the two concepts ("debug adapter driver", "jtag") by having two command groups, which initialize separately. This will help us support OpenOCD sessions using only non-JTAG transports, in which JTAG commands should not be registered. Update docs to mention that the JTAG, SVF, and XSVF commands won't work without a JTAG transport. Note that at least commands working with SRST are still inappropriately coupled to JTAG ... inappropriate because (a) SRST is not part of the JTAG standard, for all that many platforms (like ARM) expect it; and also (b) because they're used with non-JTAG debug and programming interfaces, too. They should perhaps become generic "interface" operations at some point. (Similarly with the clock rate to be used by a given adapter.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

If we only talk about "dongles" we rule out many valid setups, and help confuse some users (who may be using Dongle-free environments). Also start bringing out the point that JTAG isn't the only transport protocol, even though OpenOCD historically presumes "all is JTAG". (Not all debug adapters are JTAG adapters, or JTAG-only adapters.)
