* arm720t: virt2phys callback addedØyvind Harboe2010-02-121-4/+14
| | | | | | | | This is a copy and paste of arm926ejs. Not tested, but ready for testing at least. There is a good chance that it will work if the generic armv4_5 fn's are robust enough... Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* arm7/9: enable check that DCC downloads have been enabledØyvind Harboe2010-01-131-0/+1

* ARM720: help/usage updatesDavid Brownell2010-01-071-2/+4
| | | | | | | | | | Deprecate the "pass an instruction opcode" flavor of cp15 access in favor of the "arm mcr ..." and "arm mrc ..." commands, which offer fewer ways to break things. Use the same EBNF syntax in the code as for the user's guide. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: don't clone arm_arch_state() codeDavid Brownell2009-12-071-8/+2
| | | | | | | | | | | Have various ARM cores delegate to arm_arch_state() to display basic information, instead of duplicating that logic. This shrinks the code, makes them all report when semihosting is active, and highlights which data are specific to this core. (Like ARM720 not having separate instruction and data caches.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: rename some generic routinesDavid Brownell2009-12-071-1/+1
| | | | | | | | | | | | | | | | Rename some (mostly) generic ARM functions: armv4_5_arch_state() --> arm_arch_state() armv4_5_get_gdb_reg_list() --> arm_get_gdb_reg_list() armv4_5_init_arch_info() --> arm_init_arch_info() Cores using the microcontroller profile may want a different arch_state() routine though. (Also fix strange indentation in arm_arch_state: use tabs only! And update a call to it, removing assignment-in-conditional.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: move opcode macros to <target/arm_opcodes.h>David Brownell2009-12-071-0/+1
| | | | | | | | | | | | | | | 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 Brownell2009-12-071-4/+16
| | | | | | | | | | | | 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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: rename armv4_5_state_* as arm_state_*David Brownell2009-12-041-1/+1
| | | | | | And make arm_state_strings[] be const. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* change #include "time_support.h" to <helper/time_support.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "time_support.h" the following form should be used. #include <helper/time_support.h> The exception is from .c files in the same directory.
* target: "mcr" and "mrc" are ARM-specificDavid Brownell2009-12-011-2/+13
| | | | | | | | | | | | | | Switch "mrc" and "mcr" commands to be toplevel ARM operations, as they should initially have been. Correct the usage message for both commands: it matches ARM documentation (as one wants!) instead of reordering them to match the funky mrc() and mcr() method usage (sigh). For Cortex-A8: restore a line that got accidentally dropped, so the secure monitor mode shadow registers will show again. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* remove target_type register_command callbackZachary T Welch2009-11-241-7/+4
| | | | | | Uses chaining of command_registration structures to eliminate all target_type register_callback routines. Exports the command_handler registration arrays for those target types that are used by others.
* arm720t: use register_commands()Zachary T Welch2009-11-241-15/+23
|
* use COMMAND_REGISTER macroZachary T Welch2009-11-241-2/+2
| | | | | Replaces direct calls to register_command() with a macro, to allow its parameters to be changed and callers updated in phases.
* ARM: remove 'armv4_5_common_s' migration #defineDavid Brownell2009-11-221-2/+2
| | | | | | Finish migrating from the old symbol to the new one. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: arm_set_cpsr() handles T and J bitsDavid Brownell2009-11-221-1/+0
| | | | | | | | | | | | | | Have arm_set_cpsr() handle the two core state flags, updating the CPU state. This eliminates code in various debug_entry() paths, and marginally improves handling of the J bit. Catch and comment a few holes in the handling of the J bit on ARM926ejs cores ... it's unlikely our users will care about Jazelle mode, but we can at least warn of Impending Doom. If anyone does use it, these breadcrumbs may help them to find the right path through the code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: define two register utilitiesDavid Brownell2009-11-221-5/+7
| | | | | | | | | | | | | | Define arm_reg_current() ... returning handle to a given register, and encapsulating the current mode's register shadowing. It's got one current use, for reporting the current register set to GDB. This will let later patches clean up much ARMV4_5_CORE_REG_MODE() nastiness, saving a bit of code. Define and use arm_set_cpsr() ... initially it updates the cached CPSR and sets up state used by arm_reg_current(), plus any SPSR handle. (Later: can also set up for T and J bits.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: simplify CPSR handlingDavid Brownell2009-11-221-4/+4
| | | | | | | | | | | | | | Stash a pointer to the CPSR in the "struct arm", to help get rid of the (common) references to its index in the register cache. This removes almost all references to CPSR offsets outside of the toplevel ARM code ... except a pair related to the current ARM11 "simulator" logic (which should be removable soonish). This is a net minor code shrink of a few hundred bytes of object code, and also makes the code more readable. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: add arm_mode_name()David Brownell2009-11-171-1/+1
| | | | | | | | | | | | | | | Add and use arm_mode_name() to map from PSR bits to user meaningful names. It uses a new table which, later, can be used to hold other mode-coupled data. Add definitions for the "Secure Monitor" mode, as seen on some ARM11 cores (like ARM1176) and on Cortex-A8. The previous mode name scheme didn't understand that mode. Remove the old mechanism ... there were two copies, caused by Cortex-A8 needing to add "Secure Monitor" mode support. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* command_handler: change 'cmd_ctx' to CMD_CTXZachary T Welch2009-11-171-7/+7
| | | | Convert all command handler 'cmd_ctx' parameter usage with CMD_CTX.
* command_handler: change 'args' to CMD_ARGVZachary T Welch2009-11-171-2/+2
| | | | | This patch converts all instances of 'args' in COMMAND_HANDLER routines to use CMD_ARGV macro.
* command_handler: change to 'argc' to CMD_ARGCZachary T Welch2009-11-171-3/+3
| | | | | This patch converts all instances of 'argc' in COMMAND_HANDLER routines to use CMD_ARGC.
* ARM7TDMI: remove now-needless "struct arm7tdmi"David Brownell2009-11-171-10/+9
| | | | Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: no implicit #includes of "register.h"David Brownell2009-11-161-0/+1
| | | | | | | | | | | | Same deal: "register.h" got needlessly included all over the place because of being in a few widely included headers. So take it out of the header files which included it, and put it in files which use it ... reduce needless interdependencies. Also, don't need that extra "types.h" inclusion. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: memory utils aren't ARM7/ARM9 dependentDavid Brownell2009-11-151-2/+3
| | | | | | | | | | | | | | | | The arm7_9_checksum_memory() and arm7_9_blank_check_memory() routines are not actually specific to the ARM7 and ARM9 core generations ... they can work for any core which can run algorithms using basic ARM (not Thumb) instructions. Rename them; move the declarations to a more generic site; likewise move the code (and tidy it a bit in the process). NOTE: the blank_check() method falsely returned a success status (0) on one error path, when the algorithm failed. Fixed this bug. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM7/ARM9: use shared examine() methodDavid Brownell2009-11-131-2/+1
| | | | | | | | | No point in having two identical examine methods for the ARM7TDMI and ARM9TDMI drivers; move, rename, shrink, share. Add a bit of doxygen; stop needlessly exporting a method. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | Remove misleading typedef and redundant suffix from struct arm720t_common.
* scan_field_t -> struct scan_fieldZachary T Welch2009-11-131-1/+1
| | | | Remove useless structure typedef.
* jtag_tap_t -> struct jtag_tapZachary T Welch2009-11-131-1/+1
| | | | | Search and destroy the jtag_tap_t typedef. This also cleans up a layering violation, removing the declaration from types.h.
* add CMD_NAME macro for command handlersZachary T Welch2009-11-131-1/+1
| | | | | By introducing the CMD_NAME macro, this parameter may be integrated as args[-1] in command.[ch], without touching any other call sites.

| | | | | | | | Use target_to_arm720(), replacing needless pointer traversals and simplifying a bunch of nasty code. Stop setting arch_info for arm720 type parts, it's not used any longer. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM720: remove exports and forward declsDavid Brownell2009-11-051-119/+95
| | | | | | | | | | | | | | Unneeded exports cause confusion about the module interfaces. Make all functions static. Add a short header comment. The forward decls are just code clutter; remove them, by moving their references after definitions. This is another file which never needed even one internal forward declaration. Remove unneeded indirection for the write_memory() method. Make a table static, remove a can't-happen case with nasty exit(). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
