da96d3d41b target: riscv-011: don't change 'debug_level' during target polling
In the riscv fork, [1] has disable the debug log during target
polling, with message:
	Improve low-level logging.

	Now logging is consistent and more readable.
	I did remove most logging during riscv_poll() since it clutters
	up the log/screen and is not generally helpful.

This is questionable, because if the user enables the debug log,
the messages should all be logged.

Drop the code that overwrites the 'debug_level'.

56141bb349 target: riscv: Drop new typedefs added by the updated riscv-debug-spec files
The advantage of this patch is that it brings the new code closer to
OpenOCD coding style - the disadvantage is that it involves modifying
autogenerated files, making it harder to drop in new versions when
riscv-debug-spec changes.

Checkpatch-ignore TRAILING_SEMICOLON is added to allow a construct in

1b0ffa97ea target: get_gdb_arch() accepts target via const pointer
The function in question does not need to change target state. It is a
target-type-dependant function, however, IMHO, it is safe to assume that
any target type would not need to change type-independant state of a
target to figure out the arch.

a5108240f9 target: fix messages and return values of failed op because not halted
Lot of messages was logged as LOG_WARNING, but the operation failed
immediately. Sometimes no error message was logged at all.
Add missing messages, change warnings to errors.

Sometimes ERROR_TARGET_INVALID was returned. Some command handlers
returned ERROR_OK! Always return ERROR_TARGET_NOT_HALTED.

While on it use LOG_TARGET_ERROR() whenever possible.
Prefix command_print() message with 'Error:' to get closer
to LOG_TARGET_ERROR() variant.

Error message was not added to get() and set() methods of
struct xxx_reg_type - the return value is properly checked and a message
is logged by the caller in case of ERROR_TARGET_NOT_HALTED.

44ed26a1db target/riscv: fix use of uninitialized value
Scan-build reports:
	Logic error: Uninitialized argument value
	riscv.c:2688 2nd function call argument is an uninitialized value

This is a real error cause by running the command "riscv
authdata_write" without arguments. In such case 'value' is not
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'.

fd2a44ab55 target/riscv: fix undefined operation
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.

aff48a6a31 target/riscv: fix dead assignment

	Unused code: Dead nested assignment
	riscv.c:459 Although the value stored to 'ir_user4_raw' is
		used in the enclosing expression, the value is
		never actually read from 'ir_user4_raw'

This is caused by the value reassigned in 'ir_user4_raw':

but never used.

Drop the DIY conversion in favor of h_u32_to_le() that does not

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.
