ddef9cf73b target: align switch and case statements
The coding style requires the 'case' to be at the same indentation
level of its 'switch' statement.

Align the code accordingly.

While there:
- add space around the operators;
- drop useless empty line.

Skip all riscv code, as it is going to be updated soon from the
external fork.

No changes are reported by
	git log -p -w --ignore-blank-lines --patience

003cb92cd5 openocd: drop empty string suffix from format strings
Format strings are often split to allow using the conversion
specifiers macros from <inttypes.h>.
When the format string ends with one of such macros, there is no
need to add an empty string "" after the macro.

In current code we have 203 cases of empty string present, against
1159 cases of string ending with the macro.

Uniform the style across OpenOCD by removing the empty string.

Don't modify the files 'angie.c' and 'max32xxx.c' as they are
already changed by other independent commits.

3b38226370 mips32: add per-cpu quirks feature
Introduce the ability to detect CPUs based on CP0 PRId register and
apply cpu specific quirks, which alter the default ejtag behavior.

First of those is EJTAG_QUIRK_PAD_DRET, which makes sure extra NOPs are
placed after the DRET instruction on exit from debug mode. This fixes
resume behavior on Ingenic JZ4780 SoC.

The proper detection of some (currently unsupported) CPUs becomes quite
complicated, so please consult the following Linux kernel code when
adding new CPUs:
* arch/mips/include/asm/cpu.h
* arch/mips/kernel/cpu-probe.c

fb43f1ff4e target: Rework 'set' variable of break-/watchpoints
The 'set' variable name suggests a boolean data type which determines
whether a breakpoint (or watchpoint) is active. However, it is also
used to store the number of the breakpoint.

This encoding leads to inconsistent value assignments: boolean and
integer values are mixed. Also, associated hardware comparator
numbers, which are usually numbered from 0, cannot be used directly.
An additional offset is required to store the comparator numbers.

In order to make the code more readable and the value assignment more
consistent, change the variable name to 'is_set', its data type to 'bool'
and introduce a dedicated variable for the break-/watchpoint
number.

In order to make the review easier, the data types of various related
variables (e.g. number of breakpoints) are not changed.

While at it, fix a few coding style issues.

In target/openrisc/jsp_server.c, an error is logged if the ptr was

246782229f smp: replace commands smp_on/smp_off with "smp [on|off]"
Seams over-engineered having two separate commands to turn SMP
on/off. Plus it is missing the possibility to dump the current
status of SMP and would be weird adding an additional command
for it. Moreover, such commands are replicated in few targets so
it would make sense centralizing them.

- Deprecate the commands "smp_on" and "smp_off".
- Add a new command "smp" that accepts optional parameters
  "[on|off]" and prints the SMP status when run without
  parameters. This replaces the two commands above.
- Put the deprecated and the new command handlers in smp.c
- Update the documentation, except for mips_m4k, since it is not
  available yet.
- Promote the macro foreach_smp_target to global context and use
  it where possible.

There is no need to implement scan code in functions
mips_ejtag_get_idcode/impcode(), use mips_ejtag_drscan_32().
Impcode/idcode saved in ejtag.info.

2279c23cde mips32, add support for micromips in debug mode
Micromips is 16bit oriented, branch and jumps are
16 bit based. The upper half 16bits of a 32bit instruction
with the major opcode, must go first in the instruction
stream, hence the SWAP16 macro and swap16 array function,
needed if the code is written as 32 bit word in little endian
cores. Endianess info added to ejtag_iinfo. Pointer to
ejtag_info and isa field added to pracc context.
MIPS32 code are renamed to MIPS32_ISA_...
To select the isa, the new code has an additional isa parameter
(1 for micromips, 0 for mips32).
In JR instruction the isa bit must be set to execute
micromips code.
The suffix u is added to the OP codes to avoid signed/unsigned
comparison errors and to make sure the right shift is
performed logically.
The isa in debug mode is updated in the poll function.
Code for miniprograms, in kernel mode, need to be converted.
CFI code only for mips32.

47b8cf8420 target: Add 64-bit target address support
Define a target_addr_t type to support 32-bit and 64-bit addresses at
the same time. Also define matching TARGET_PRI*ADDR format macros as
well as a convenient TARGET_ADDR_FMT.

In targets that are 32-bit (avr32, nds32, arm7/9/11, fm4, xmc1000)
be least invasive by leaving the formatting unchanged apart from the
type;
for generic code adopt TARGET_ADDR_FMT as unified address format.

Don't silently change gdb formatting here, leave that to later.

Add COMMAND_PARSE_ADDRESS() macro to abstract the address type.
Implement it using its own parse_target_addr() function, in the hopes
of catching pointer type mismatches better.

Add '--disable-target64' configure option to revert to previous 32-bit
target address behavior.

8825804273 target: improve robustness of reset command
Before this change jim_target_reset() checked examined state of a target
and failed without calling .assert_reset in particular target layer
(and without comprehensible warning to user).
Cortex-M target (which refuses access to DP under active SRST):
If connection is lost then reset process fails before asserting SRST
and connection with MCU is not restored.
This resulted in:
1) A lot of Cortex-M MCUs required use of reset button or cycling power
after firmware blocked SWD access somehow (sleep, misconfigured clock etc).
If firmware blocks SWD access early during initialization, a MCU could
become completely inaccessible by SWD.
2) If OpenOCD is (re)started and a MCU is in a broken state unresponsive
to SWD, reset command does not work even if it could help to restore communication.
Hopefully this scenario is not possible under full JTAG.

jim_target_reset() in target.c now does not check examined state
and delegates this task to a particular target. All targets have been checked
and xx_assert_reset() (or xx_deassert_reset()) procedures were changed
to check examined state if needed. Targets except arm11, cortex_a and cortex_m
just fail if target is not examined although it may be possible to use
at least hw reset. Left as TODO for developers familiar with these targets.

cortex_m_assert_reset(): memory access errors are stored
instead of immediate returning them to a higher level.
Errors from less important reads/writes are ignored.
Requested reset always leads to a configured action.

arm11_assert_reset() just asserts hw reset in case of not examined target.
cortex_a_assert_reset() works as usual in case of not examined target.

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.
