Simon Smiganovski 0d055602c3 flash/nor/stm32f1x: adjust size of the flash loader buffer
target_run_flash_async_algorithm expects the source_buffer to have
at least 2 words reserved for read and write pointers in addition to the
FIFO buffer. If the size of the data to be flashed is <= 8 bytes then
the flash function will fail with "corrupted fifo read pointer" error.

Ensure the allocated buffer is big enough to hold both FIFO buffer and
read/write pointers.

Tomas Vanek 6939187853 target/armv7m: prevent saving and restoring non existent regs
armv7m_start_algorithm() saves register values to arch_info->context.
armv7m_wait_algorithm() restores register values from arch_info->context.
Exclude registers with flag exist = false from both loops.

While on it refactor the register restore: introduce 'struct reg' pointer
and dereference it instead of numerous accesses by a full path
from armv7m pointer.

Antonio Borneo fb23c9c10b rtos: hwthread: fix clang error core.NullDereference
Clang spots a potential NULL pointer dereferencing that is instead
an incorrect use of an array of pointers:

	src/rtos/hwthread.c:254:32: warning: Dereference of null pointer
	  [core.NullDereference]
		(*rtos_reg_list)[j].number = (*reg_list)[i].number;
		                             ^~~~~~~~~~~~~~~~~~~~~
The error has not been spotted before because:
- this function is not called for the first core of the SMP node,
- for the other cores on Cortex-A it still returns valid register
  value for the first 12 ARM registers, then it diverges.

Also Valgrind does not spot any issue at runtime.

Address the array correctly.

While there, use DIV_ROUND_UP() macro for the computation.

Commit 0cedf10f8f ("Remove duplicate of a counter in

In the second foreach_smp_target() loop, variable "threads_found"

counting of threads_found from the second loop, the
incorrect thread counter value gets passed to hwthread_fill_thread().

Tomas Vanek 3da0c2504c jtag/drivers/cmsis_dap: prevent CDC missdetect as CMSIS-DAP bulk
The autodetection of CMSIS-DAP v2 bulk interface is tricky
as not all adapters conform CMSIS-DAP specs.

If an interface has a string descriptor containing CMSIS-DAP,
then OpenOCD did not insisted on the correct interface class
LIBUSB_CLASS_VENDOR_SPEC.

However the relaxed test caused false autodetection of v2 bulk
interface on some CMSIS-DAP v1 adapters with an additional serial
interface with the string descriptor stupidly containing
CMSIS-DAP text.

Make the test less relaxed, refuse autodetection of the interfaces
with the class number of well known functions including CDC and MSC.

Antonio Borneo 7a09635735 openrisc: fix clang error core.CallAndMessage
Clang assumes that size could assume a value that is not 1 nor 2
nor 4. In such condition the buffer in t is allocated (size != 1)
and not initialized. This triggers an error:
  src/target/openrisc/or1k_du_adv.c:655:14: warning: 2nd function
    call argument is an uninitialized value [core.CallAndMessage]
                crc_calc = adbg_compute_crc(crc_calc, data[i], 8);
                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Add the default case to cover other values of size.

After this fix, clang still complains on the same line, this time
misunderstanding the limits of the loop and considering that
buf_bswap16() only swaps the first 16 bits, thus passing not
initialized value data[2] to adbg_compute_crc()

Replace malloc() with calloc() to silent it.

step over BP/WP before resuming.
For example; in the case of WPs (DEBUGCAUSE_DB), in the current

`TARGET_EVENT_HALTED` after the original one caused by WP itself.

This patch moves the halted event cb call after
the step is done successfully.

Jonathan Bell ee87f2b4a9 jtag/drivers: bcm2835gpio: implement memory barriers when bitbashing
This GPIO driver is common to SoCs that have in-order ARM cores
(BCM2835) as well as superscalar (BCM2836-7) and speculative
out-of-order cores (BCM2711).

For BCM2837 and BCM2711, the processor can dual-issue stores and
is free to merge writes to peripheral memory for pages mapped
MT_NORMAL_NC, which is the default provided by /dev/[gpio]mem.

This can cause glitches (or missing edges) on GPIO pins when
toggled with no delay, as pipelined writes to the same address
can get arbitrarily squelched.

To prevent this happening, make sure the preceding write ops are
flushed outside the shareable domain by using a memory barrier.

Keith Packard af75d70dc5 flash/nor/at91samd: Use 32-bit register writes for ST-Link compat
ST-Link v2 dongles can be used with many cortex-m parts, but they have
one limitation -- they can only perform 8-bit and 32-bit writes to the
target. 16-bit writes are done using a pair of 8-bit writes. While not
usually an issue, in the case of the at91samd flash driver, the 16-bit
'command' register must have both halves written in the same
operation.

Fortunately, this register has two pad bytes above it in the address
space, making it safe to always access with 32-bit operations.

This is a real error cause by running the command "riscv

initialized and is passed to and used by r->authdata_write().

Reorganize the code to:
- detect the correct amount or command's arguments;
- drop the LOG_ERROR() on ERROR_COMMAND_SYNTAX_ERROR;
- drop the 'else' after 'return'.

Scan-build reports:
	Logic error: Result of operation is garbage or undefined
	riscv.c:1614 The result of the left shift is undefined due
		to shifting by '4294967281', which is greater or
		equal to the width of type 'target_addr_t'

This is a false warning due to clang that considers the impossible
case of 32 bits hart (xlen = 32) in SATP_MODE_SV48 mode
(info->va_bits = 48).
Under such case:
	riscv.c:1614 ... ((target_addr_t)1 << (xlen - (info->va_bits - 1))) ...
the shift amount wraps around the unsigned type and assumes the
value 4294967281 (0xfffffff1).

Use assert() to prevent clang from complaining.
