* ARM: move opcode macros to <target/arm_opcodes.h>David Brownell2009-12-0718-249/+281
| | | | | | | | | | | | | | | Move the ARM opcode macros from <target/armv4_5.h>, and a few Thumb2 ones from <target/armv7m.h>, to more appropriate homes in a new <target/arm_opcodes.h> file. Removed duplicate opcodes from that v7m/Thumb2 set. Protected a few macro argument references by adding missing parentheses. Tightening up some of the line lengths turned up a curious artifact: the macros for the Thumb opcodes are all 32 bits wide, not 16 bits. There's currently no explanation for why it's done that way...

* ARM: remove mrc_opcode(), use MRC() or MCR()David Brownell2009-12-073-20/+32
| | | | | | | | | | | | Get rid of mrc_opcode() in favor of ARMV4_5_MRC() or, where arm*20t should have used it, ARMV4_5_MCR() instead. Basically, *writing* coprocessor registers shouldn't have used the *read* opcode ... and both should stick to standard opcode constructors, not rearranging parameter sequence any more than already needed.

* ARM: disassemble two more v6+ instructionsDavid Brownell2009-12-071-12/+71
| | | | | | | | | | | The SRS and RFE instructions speed exception entry/exit by making it easy to save and restore PC and SPSR. This handles both ARM and Thumb2 encodings. Fix minor PLD goofage; that "should never reach this point" can't happen, so remove it. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM DPM: don't write low bits of watchpoint valueDavid Brownell2009-12-071-1/+1
| | | | | | | The low two bits are defined as should-be-zero-or-presereved. We'll take the zero option, it's easier to enforce. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* OMAP2420: define reset-assert eventDavid Brownell2009-12-071-0/+7
| | | | | | | | | Behave like OMAP3530: force global software reset. Given the patch to teach ARM11 how to use these events, and use VCR to catch the reset vector, this works better than either the current reset logic or than using SRST.

* add 'flash list', rewrite 'flash banks'Zachary T Welch2009-12-063-22/+36
| | | | | | | Rename the existing 'flash banks' implementation as 'flash list', and replace the broken 'flash_banks' TCL wrapper with a new command handler. Adds documentation for the new 'flash list' command in the user guide.
* allow 'flash_banks' command to give GDB outputZachary T Welch2009-12-061-1/+1
| | | | | | | | | The 'flash banks' command produces a list that needs to be formatted properly for GDB's 'mem info' to work properly. The flash_banks TCL wrapper provided this formatting, but wrappers no longer work for second-level commands as they did in the past. With this patch, the 'flash_banks' command can be used with the new command syntax and display the required information.
* fix NOR flash regressionZachary T Welch2009-12-061-0/+2
| | | | | When factoring the bank setup command into flash_bank_add(), I forgot to include a call to the new helper.
* misc code review updatesDavid Brownell2009-12-054-14/+11
| | | | | | | | | More updates from the code review by Steve Grubb <sgrubb@redhat.com>. The Jim float-comparision bug just gets a comment not a fix, though. Cc: Steve Grubb <sgrubb@redhat.com>. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* rename nand.h to flash//nand/core.hZachary T Welch2009-12-0420-28/+33
| | | | | | | | | Rename nand.h as flash/nand/core.h, chase consumers. The public APIs need to be sorted out with imp.h, but this allows other changes to begin improving the separation between policy and mechanism. Moves #include <target/target.h> and #include "driver.h" into the internal headers or source files, removing it from <flash/nand/core.h>.
* move remaining nand helper filesZachary T Welch2009-12-048-11/+9
| | | | Move remaining NAND implementation files into src/flash/nand/.
* split nand.c into nand/{core,fileio,tcl}.cZachary T Welch2009-12-047-872/+1005
| | | | | | | Moves commands into nand/tcl.c and core implementation to 'nand/core.c' and 'nand/fileio.c'. Eliminates 'flash/nand.c'. Adds 'nand/imp.h' to share routines between TCL commands and core.
* split NAND driver handling into nand/driver.[ch]Zachary T Welch2009-12-045-104/+205
| | | | | | | This work parallels the NOR directory, encapsulating the NAND drivers into a separate file. This takes an extra step by encapsulating the type of data structure used to manage the drivers, allowing it to be changed from an array to a dynamic list in the future.

* ARM: misc generic cleanupDavid Brownell2009-12-044-13/+28
| | | | | | | | | | | Remove an undesirable use of the CPSR symbol ... it needs to vanish. Flag mode-to-number stuff as obsolete; say why ... should also vanish. Get rid of no-longer-used mode and state typedefs. Comment a few of the implicit ties to "classic ARM". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ARM11: tweak TAP ops and debuggingDavid Brownell2009-12-042-23/+61
| | | | | | | | | | | | | | | | | | Tweak scanchain 7 debug messaging: - show register addresses in decimal, matching ARM docs; - remove some pointless noise Avoid some needless roundtrips: - skip SCAN_N when SCREG already holds that number (speeds up polling and other common operations) - avoid zeroing vcr twice on resume Show the IR opcode as a label ("RESTART") too; and in decimal, matching ARM docs.

* reorder build order of src directoryZachary T Welch2009-12-041-1/+9
| | | | Descend into the library modules in order, from bottom-to-top.
* remove flash.h from treeZachary T Welch2009-12-0418-63/+4
| | | | | Remove the now vestigial <flash/flash.h> header from the tree, replacing a few references with <flash/nor/core.h>
* split flash.h into into flash/nor/*.hZachary T Welch2009-12-046-326/+358
| | | | | | | | | Move the bulk of the flash.h file into flash/nor/core.h, leaving an empty husk that will be removed in the next patch. The NOR driver structure is an implementation detail, so move it into its own private header file <flash/nor/driver.h> along with helper declaration for finding them by name.
* remove target.h from flash.hZachary T Welch2009-12-0421-20/+31
| | | | | The flash.h header does not require the target.h header file, but its implementation source files do. Move it to flash/nor/imp.h.
* split NOR and NAND flash headersZachary T Welch2009-12-044-12/+15
| | | | | Moves common flash errors to <flash/common.h> to decouple these two mostly unrelated trees of code.
* eliminate src/flash/flash.cZachary T Welch2009-12-043-221/+187
| | | | | Move remaining NOR flash implemenation into flash/nor/core.c Removes flash.c from the build, leaving only its header to split.
* add flash/nor/drivers.cZachary T Welch2009-12-044-55/+79
| | | | | Encapsulates access to the flash_drivers array, providing a base of operations for future dynamic driver module loading features.
* move more nor flash implementation detailsZachary T Welch2009-12-045-999/+1011
| | | | | | | | Splits the exec mode commands out of flash.c into the flash/nor/ files. The routines used by these high-level commands are moved into nor/core.c, with their internal declarations placed in nor/imp.h. Fixes distribution of <flash/nor/core.h> header.
* ARM: semihosting entry cleanupDavid Brownell2009-12-041-8/+39
| | | | | | | | | Clean up arm_semihosting() entry a bit, comment some issues and just which SVC opcodes are getting intercepted. Microcontroller profile cores will need a new entry, since they use BKPT instead (and don't have either SVC mode or an SPSR register). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: remove semihosting globalsDavid Brownell2009-12-045-33/+48
| | | | | | | | Store a flag and errno in in "struct arm". Have "poll" output report when semihosting is active. Shrink some of the affected lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* add flash/nor/core.[ch]Zachary T Welch2009-12-045-62/+149
| | | | | | | | | | | | | | | The newly moved flash TCL routines access the internals of the module too much. Fix the layering issues by adding new core NOR flash APIs: <flash/nor/core.h>: - flash_driver_find_by_name() - self-descriptive <flash/nor/imp.h>: - flash_bank_add() - encapsulates adding banks to bank list - flash_bank_list() - encapsulates retreiving bank list This allows the externs in flash/nor/imp.h to be removed, and these mechanisms may now be re-used by other flash module code.
* add flash/nor/{tcl.c,imp.h} from flash/flash.cZachary T Welch2009-12-044-175/+235
| | | | | | Moves the top-level 'flash' command handlers into flash/nor/tcl.c, with flash/nor/imp.h providing an internal implementation header to share non-public API components.
* separate Jim from jtag/core.cZachary T Welch2009-12-042-11/+11
| | | | | | After previous efforts, only one Jim routine remained in jtag/core.c, and moving it to jtag/tcl.c painlessly finishes separating these layers. The headers need separating, but the implementation is clean.
* switch 'rm' command away from using JimZachary T Welch2009-12-041-18/+11
| | | | | Commands that do not need to use Jim should be registered as high-level command handlers.
* check top-level command registrationsZachary T Welch2009-12-041-16/+34
| | | | | | | When calling module_register_commands, the return value needs to be checked for failures. Instead of duplicating code, use an array of function pointers to the identical registration functions to iterate over during startup.
* allow 'jtag init' to be run in any modeZachary T Welch2009-12-041-1/+1
