d1ae39efc0 etm: prevent segfault when reading bogus information
When I do not have the JTAG adapter connected to the target, I often
end up always reading 1s from the chain. If the OpenOCD is configured
to connect to an ETM-equipped target (i.MX25 ARM9 in my case), this
results in writing garbage values in the etm reg_cache as the ETM bit
fields for the comparators, counters and outputs are wider than the
amount of entries in the corresponding arrays. This later results in a
segfault in the first etm_reg_lookup() call.

3610f2f09b mips32_pracc: jump to 0xff20.0200 if cpu reads wrong addr
On some CPUs, like bcm7401 with EJTAG v2.0 we can have situation where
CPU do not stops execution. For example, all CP0 commands will have this issue.
In this case we should some hove recover our session. Currently
jump to 0xff20.0200 seems to be good option. If it brake some thing on
newer EJTAG, then check for EJTAG v2.0 should be added.

2d146a9321 oocd_trace: fix warnings
gcc (Gentoo Hardened 4.6.3 p1.13) produces a warning about the variable
assigned but not used. write() can sometimes write less than the specified
count so it's marked with warn_unused_result in the system headers and its
return value can't be ignored. The most correct solution would be to have a
loop writing the buffer until all bytes are written or an error is
returned but here it's impractical.

9188a9bc68 target: xscale make reset init work properly
On XScale architecture, to write debug control register DCSR
and activate JTAG debug (ie. to choose Halt Mode), the
enabling can only be done while the board is held in reset
state (ie. PXAxx #RST line held low).

The current implementation writes to the register before
asserting the SRST line. Swap the order to activate the SRST
line before writing to DCSR.

This way, the new xscale command is :
 - xscale vector_catch
   Reads back to the user the current vector catching status
 - xscale vector_catch reset dabt pabt
   Sets the caught vectors to data abort and prefetch abort
   for example.

This is mostly taken from Cortex-M3 openocd code.

b8c44b3fd7 [RFC] mips: Enable bulk write optimization for all writes
mips_m4k_bulk_write_memory was only called from target_write_buffer as an
optimization when the word count was large enough.

Remove mips_m4k_bulk_write_memory from the target type, causing the default
implementation to call the regular mips_m4k_write_memory instead.

Perform the dispatch to bulk write in mips_m4k_write_memory, enabling the
optimization for target_write_memory() writes with size 4, in addition to
target_write_buffer() writes.

It also enables making the choice of bulk write vs regular write
specifically for the architecture and not relying on the generic target
code to make a sensible decision.

However, there're some other places (mips_m4k, arm7_9_common) where
adding RESET_SRST_PULLS_TRST would lead to trying to use SRST even if

d5e564625f mips: m4k alternate pracc code. Patch 3
Functions mips32_pracc_read_mem(), mips32_cp0_read() and mips32_pracc_read_regs() are now modified.
mips32_cp0_read() is very similar to mips32_read_u32() with one store access.
mips32_pracc_read_regs() is the only function that can not be executed from only one queue.
Now this function is modified to use reg8, it saves all the registers but does not restore reg8.
To remedy this, mips_ejtag_config_step() is called after mips32_save_context() in
mips_m4k_debug_entry(). Function mips_ejtag_config_step() is modified to use reg8 and
restore it from ejtag info instead of using DeSave for save/restore.

37c28903a1 mips: m4k alternate pracc code. Patch 2
Each pracc function defines a variable ctx of type struct pracc_queue_info.
To simplify the code tree auxiliary functions are defined: pracc_queue_init(), pracc_add() and
pracc_queue_free().
The second parameter in pracc_add() is the store address if the instruction is a store at dmseg,
otherwise it should be 0.
The code is executed by mips32_pracc_queue_exec(). If ejtag_info->mode is 0 mips32_pracc_exec()
is called and it should work like with current code.
To generate the delay between scans the number of clock ticks are calculated with the help of
jtag_get_speed_khz(). Due to delays in the execution of each single ftdi instruction the number of ticks
are higher as it should be, specially at higher scan rates.
mips32_pracc_read_u32() should now work with the new code.

109f37c161 mips: m4k alternate pracc code. Patch 1
This patch and the following patches define another way of doing processor access without the need to read back
the pracc address as needed in current pracc code.
Current pracc code is executed linearly and unconditionally. The processor starts execution at 0xff200200
and the fetch address is ever incremented by 4, including the last instruction in the delay slot of the branch to start.
Most of the processor accesses are fetch and some are store accesses.
After a previous patch regarding the way of restoring registers (reg8 and reg9), there are no load processor accesses.
The pracc address for a store depends only on the store instruction given before.
m4k core has a 5 stage pipeline and the memory access is done in the 3rth stage. This means that the store access
will not arrive immediately after a store instruction, it appears after another instruction enters the pipeline.
For reference: MD00249 mips32 m4k manual.
A new struct pracc_queue_info is defined to help each function in generating the code. The field pracc_list holds in the
lower half the list of instructions and in the upper half the store addressess, if any. In this way the list can be used by
current code or by the new one to generate the sequence of pracc accesses.
For every pracc access only one scan to register "all" is used by calling the new function mips_ejtag_add_scan_96().
This function does not call jtag_execute_queue(), all the scans needed can be queued before calling for execution.
The pracc bit is not checked before execution, is checked after the queue has been executed.
Without calling the wait function the code works much faster, but the scan frequency must be limited. For pic32mx
with core clock at 4Mhz works  up to 600Khz and with 8Mhz up to 1200. To increase the scan frequency a delay
between scans is added by calling jtag_add_cloks().
A time delay in nano seconds is stored in scan_delay, a new field in ejtag_info, and a handler is provided for it.
A mode field is added to ejtag_info to hold the working mode. If a time delay of 2ms (2000000 ns) or higher is set,
current code is executed, if lower, new code is executed.
Initial default values are set in function mips32_init_arch_info. A reset does not change this settings.

37a6e40250 mips: change in restoring debug working register
In current devel code there are 3 functions (related to m4k code) that need to restore register 8 from pracc stack:
mips32_pracc_read_u32()
mips32_cp0_read()
mips32_pracc_write_mem_generic()

And mips32_pracc_read_mem() needs to restore regs 8 and 9 from pracc stack.

Values in this registers should be the same as read by mips32_pracc_read_regs() when entering debug
mode and can be modified by mips32_pracc_write_regs() when leaving debug mode.
There is no need to read their values from the processor registers every time.

The fields reg8 and reg9 are added to struct mips_ejtag to store these register values
and the call to mips32_save_context() is shifted in mips_m4k_debug_entry() in order
to store them before any other function needs to restore these registers.
For the same reason in function mips_m4k_step() the call to mips_m4k_set_breakpoint(), if needed,
should be made after calling mips_m4k_debug_entry().
For single word write the number of pracc accesses are now 9 or 8, from 13 or 12 in current code,
single word read takes now 10 instead of 12.

This patch is really the first in a set of patches for an alternate m4k pracc code
much faster that current code. At least for me with pic32mx works fine.

2dde122b66 mips: mips32_pracc_fastdata_xfer() little modification
In this function after loading the handler code and the jump code there is a call
to wait_for_pracc_rw() to verify that a pracc access is pending.
Next the address is read to verify that the handler is running, the address should be at
fastdata area.
Next, another call is made to wait_for_pracc_rw(). This call is not needed, we now already
that a pracc access is pending.
Better we call this function before loading the end address to be sure it is loaded correctly.

c185a5b724 pic32mx: false pending at low core clock
To show up the fail try to step with the core clock set to 31.25Khz
and with a ftdi/hs adapter or with a wiggler, -not with ft2232-.
The scan frequency should be set to 300Khz or higher, at lower frequency probably will not fail.

The code exits with error because the pracc address is at 0x0.

It also fails when using the "all" register, but in this case the code works without any message because the
pracc address is at 0xff202004 when it fails.

I never saw this fail with the core clock set to 500Khz or higher, but ...

The workaround simply puts a 1 ms delay after the execution of the DERET instruction.

no need to save any register, they will be overwritten.
Like in the previous patch, for speed optimization in write code,
same instructions can be saved if the lower half word or the upper
half word is 0.
If the lower half word is 0, it can be loaded with only a lui instruction.
If the higher half word is 0 it can be done with an ori instruction with register 0.
This code saves 10 pracc accesses at a minimum, and 40 at a maximum,
obviously if register 2 to 31 are 0 or a half word is 0
Current code needs 91 pracc accesses.

This function is highly optimized, there is not much to
improve.
Loading the base address for pracc access with the new
defined MIPS32_PRACC_BASE_ADDR saves one instruction.
The memory address is loaded in too steps. First the upper
address is loaded. The lower address is passed as an offset in
the memory load instruction.
The offset is signed, if the lower address is in the range of
0x8000 to 0xffff the offset is a negative value, and the upper
address must be incremented by 1.
Pracc accesses are now 12 instead of 14.

9aad563d15 mips: code clean up in mips_m4k_debug_entry() function
The function mips_ejtag_read_debug() is defined in mips_ejtag.c
and is called only by mips_m4k_debug_entry() for reading the
CP0 debug register. The comment in this function is obviously wrong.
There is a generic function to read CP0 registers with similar code.
A call to mips32_cp0_read() should work in the same way.
The purpose of reading the debug register is to test if the DSS
bit is set and clear the SSt bit.
It is faster and easier if the SSt bit is cleared without any check.
Remark: DSS bit set only means that a debug single-step exception
ocurred, but it is not possible to step over a sdbbp instruction,
in this case DSS will not be set and the SSt bit not cleared by code.
Resume command at another address will step, so really the behavior
is not the same.

"Debug : Interrupt handlers didn't complete within time,

Cause : Given a breakpoint is set on the lower half word and the PC is on
the upper half word. When another breakpoint is now set on the current PC
then resuming the core will not result in a break on the newly set
breakpoint. This has been observed on a STM32F1x, STM32F2x (CM3) but not
on a STM32F0x (CM0). It's not clear if this is a STM32F1/F2 only or a
general CM3 problem.

9c9c06b8ae arm946e: don't use global variables for context
Global variables 'dc' 'ic' had been used in the code
to keep target's state of D-cache and I-cache
on debug entry.

This may lead to incorrect operation in configurations
with multiple cores and unequal cache states.

Fix: move cache state to the appropriate bits of the
'cp15_control_reg' field (already present but unused).
Vaule of cp15 control register stored here on
arm946e_post_debug_entry(), and analyzed later

1274df07f1 Bug in src/target/mips32_pracc.c
The bug shows up with the command "mdw addres count" and only if count>1024 (count>0x400).
The first 1024 values shows as expected, but the rest of the values  are wrong.
Name of variable  bytesread" is changed to "wordsread" to reflect what really does.

7151398cff stlink: fix alignment build warning
The {read,write}_mem32 interface functions was asking a 32 bits buffer
but they don't need 32 bits alignment.
This will change the interface to a 8 bits buffer to remove the
alignment mismatch warning. This was causing build errors on platforms
with strict aliasing rules.
