* dcache.c (dcache_read_line): New function.
(dcache_peek_byte): Use it.
(dcache_alloc): Return NULL if write of reclaimed cache line fails.
(dcache_peek_byte, dcache_poke_byte): Return failure if
dcache_alloc() returns a NULL data block pointer.
(dcache_xfer_memory): Don't force writeback unless we were writing.
* monitor.c (monitor_expect): Change places where immediate_quit
is set to 1 or 0 to increments and decrements respectively. This
allows such changes to nest properly.

-------------------------------------------------------------------
* ppc-bdm.c (bdm_ppc_wait): stop printfing ecr, der
* ocd.c: initialize remote_timeout
(ocd_wait): while looping, call ocd_do_command with OCD_AYT
(ocd_get_packet): remove find_packet goto. If there isn't
an 0x55 at the start, something is quite wrong so error out
instead of advancing in the packet and trying again. If checksum
is invalid, print error message instead of trying again.
* ser-ocd.c (ocd_readchar): error if we attempt to read past
the end of the from_wiggler_buffer.
* ocd.c (ocd_insert_breakpoint, ocd_remove_breakpoint): macro
BDM_BREAKPOINT already has braces around it, remove erroneous ones.
* ser-ocd.c (ocd_write): conditionalize on _WIN32 instead of
__CYGWIN32__
* config/powerpc/tm-ppc-eabi.h: remove BDM_NUM_REGS, BDM_REGMAP
* ppc-bdm.c: move BDM_NUM_REGS, BDM_REGMAP here from tm.h file,
fill in doc fields of bdm_ppc_ops.
(bdm_ppc_fetch_registers): don't ask for invalid registers such
as the MQ or floating point regs not present on ppc 8xx boards
(bdm_ppc_store_registers): don't write those same invalid registers
* config/i386/cygwin32.mh: stop including ocd.o ser-ocd.o
* config/powerpc/ppc-eabi.mt:

* config/powerpc/ppc-sim.mt:
* config/powerpc/ppcle-sim.mt: include ser-ocd.o
* ocd.c: move ocd_write_bytes proto to ocd.h since it is used
by ppc-bdm.c, use OCD_LOG_FILE to help debugging, define
BDM_BREAKPOINT if not defined in tm.h
(ocd_error): add new error cases
(ocd_start_remote): send the OCD_INIT command before
OCD_AYT and OCD_GET_VERSION calls, 80 was correct speed after all
(ocd_write_bytes): no longer static
(ocd_insert_breakpoint): no longer static
(ocd_remove_breakpoint): new
* ocd.h: add protos for ocd_write_bytes, ocd_insert_breakpoint,
and ocd_remove_breakpoint
* ppc-bdm.c: change bdm_ppc_ops so we call ocd_insert_breakpoint
and ocd_remove_breakpoint instead of memory_insert_breakpoint
and memory_remove_breakpoint.
(bdm_ppc_open): after calling ocd_open, modify DER
register so interrupts will drop us into debugging mode, finally
disable the watchdog timer on the board so we don't leave BDM
mode unexpectedly.
* ocd.c: move ocd_write_bytes proto to ocd.h since it is used
by ppc-bdm.c, use OCD_LOG_FILE to help debugging, define
BDM_BREAKPOINT if not defined in tm.h
(ocd_error): add new error cases

OCD_AYT and OCD_GET_VERSION calls

and ocd_remove_breakpoint
* ppc-bdm.c: change bdm_ppc_ops so we call ocd_insert_breakpoint
and ocd_remove_breakpoint instead of memory_insert_breakpoint
and memory_remove_breakpoint.
(bdm_ppc_open): after calling ocd_open, modify DER
register so interrupts will drop us into debugging mode, finally
disable the watchdog timer on the board so we don't leave BDM
mode unexpectedly.
Changes to OCD support to support wiggler box as well as
target boxes:
* ocd.c: change speed in init command to 0 from 80,
add (temporary) logging commands to help debugging,
(ocd_open): if "target ocd wiggler lpt" then use special
ser-ocd.c serial interface which communicates with Wigglers.dll,
otherwise do as we did before
(ocd_get_packet): add OCD_LOG_FILE and OCD_SET_CONNECTION to
switch of known commands of len 0
* ocd.h: add OCD_LOG_FILE
* serial.c (serial_open): do serial_interface_lookup on ocd
in the case of ocd
* ser-ocd.c: add buffer to contain responses from sending a
command to the Wigglers.dll.
(ocd_readchar): return curr char from buffer and increment ptr
(ocd_write): send buffer to Wigglers.dll, storing response in
return buffer and initializing curr location ptr to start of
buffer.
Nomenclature change. BDM is a specific type of OCD
(On chip debugging). Wiggler is the parallel port box controlled
by Wigglers.dll. The faster target box from Macraigor Systems
is not a wiggler.
* ocd.c:
* ocd.h:
* ppc-bdm.c:
* ser-ocd.c:
Replace all instances of "wiggler_" with "ocd_" and change most other
instances of "wiggler" to "ocd" or "ocd device" depending on context.
* config/m68k/monitor.mt: remove remote-wiggler.o from TDEPFILES
until OCD with that target is supported again.
* Makefile.in: add DLLTOOL = @DLLTOOL@, pass on DLLTOOL to
sub makes, change clean rule to also remove *.a to remove
libwigglers.a, in dependencies: add ppc-bdm.o ocd.o ser-ocd.o and
remove remote-wiggler.o
* configure.in: add DLLTOOL support
* configure: regenerate
* wigglers.def: new file for imports for wigglers.dll
* ser-ocd.c: new file which is layer between ocd.c and either the
wigglers.dll or the target box, only stub so far
* config/powerpc/ppc-eabi.mt: add ppc-bdm.o to TDEPFILES
* config/powerpc/ppc-sim.mt: add ppc-bdm.o to TDEPFILES
* config/i386/cygwin32.mh: add ocd.o ser-ocd.o libwigglers.a
to XDEPFILES, add rules to build libwigglers.a
checking in changes of Stu Grossman <grossman@cygnus.com>:
* remote-wiggler.c: delete
* ocd.c: new, was remote-wiggler.c
always include sys/types.h, include ocd.h, move WIGGLER
commands and many wiggler prototypes to ocd.h, make wiggler_desc
static, stop making local wiggler functions static,
define write_mem_command for wiggler_write_bytes
(wiggler_start_remote): stop hardcoding the target type,
instead set and use a target_type variable.
(wiggler_open): add new target_type and ops args
(wiggler_wait): now no longer takes pid and target_status as args,
stop trying to set target_status struct, remove BGND insn
checks
(read_bdm_registers): renamed to wiggler_read_bdm_registers
(wiggler_read_bdm_registers): numregs arg changed to reglen arg,
remove pktlen check, set reglen instead of numregs
(dump_all_bdm_regs): delete
(wiggler_fetch_registers): delete
(wiggler_prepare_to_store): now just an empty function
(wiggler_store_registers): delete
(wiggler_read_bdm_register): new
(wiggler_write_bdm_registers): new
(wiggler_write_bdm_register): new
(wiggler_write_bytes): use write_mem_command variable instead of
WIGGLER_WRITE_MEM
(get_packet): renamed to wiggler_get_packet, change refs throughout
(put_packet): renamed to wiggler_put_packet, change refs throughout
(wiggler_get_packet): add break to default case of switch,
change length of WIGGLER_GET_VERSION len to 10 from 4 to match
specs
(wiggler_mourn): unpush_target with current_ops, not &wiggler_ops
(flash_xfer_memory): delete
(noop_store_registers): new placeholder replacement for
target_store_registers() which prevents generic_load from trying to
set up the PC.
(bdm_update_flash_command): add store_registers_tmp variable,
make handling of wiggler_ops more generic -- define wiggler_ops
in a target-specific file instead (such as ppc-bdm.c in the case
of the ppc), use current_target to deal with registers again
making this file less target-specific.
(bdm_read_register_command): new
(_initialize_remote_wiggler): stop doing add_target (&wiggler_ops),
comment out add_cmd ("read-register", ...)
* ocd.h: new, contains common wiggler prototypes, command definitions

structure for ppc bdm
(bdm_ppc_open): new
(bdm_ppc_wait): new
