Philip Nye e5e2408680 gdb: Potential rounding error in reg_packet_size gdb_get_registers_packet
The calculation for reg_packet_size in gdb_get_registers_packet() could
generate a wrong result in the case of multiple registers whose size is
not a multiple of 8.

The current calculation sums the sizes for all registers then rounds the result
up to the next multiple of 8.

Instead it should round each register size up individually and sum the results for all registers.

gdb connect can fail when the flash has not been probed.

During gdb connect, the flash layout is reported, but this
can not be automatically detected for a target that is
powered up and OpenOCD supports connecting to gdb server
even if the target is powered down.

The solution is to turn of the gdb_memory_map feature.

Øyvind Harboe 051e2c99ab gdb_server: improved gdb load performance
by ack'ing memory writes immediately and reporting either
at next memory write or stepi/continue time. GDB will then
send off a new packet that is ready by the time the previous
packet has been written to target memory.

On faster adapters this can be as much as 10% improvement.

The code changes are *reasonably* clean, but perhaps it could be
made a bit more elegant, but I didn't want to change things after
I finished diagnosis/testing & submitting the patch.

The problem was that logging can send the text and the newline
separately in two different requests and the telnet code would
incorrectly remove the prompt from the end of a line.

David Brownell 6f2b88448f gdb_server: correctly report flash sector sizes
Report each region of same-size sectors separately, instead of
incorrectly reporting that every sector has the same size.

This is a longstanding bug on NOR flash chips with non-uniform
sector sizes.  It was largely hidden by other bugs in flash
handling.  When some of those were recently fixed, this one was
exposed as a regression on str710.

David Brownell 73566405b6 NOR: add optional "flash erase_address" sector padding
Add a NOR flash mechanism where erase_address ranges can be padded
out to sector boundaries, triggering a diagnostic:

  > flash erase_address 0x0001f980 16
  address range 0x0001f980 .. 0x0001f98f is not sector-aligned
  Command handler execution failed
  in procedure 'flash' called at file "command.c", line 647
  called at file "command.c", line 361
  >

  > flash erase_address pad 0x0001f980 16
  Adding extra erase range, 0x0001f800 to 0x0001f97f
  Adding extra erase range, 0x0001f990 to 0x0001fbff
  erased address 0x0001f980 (length 16) in 0.095975s (0.163 kb/s)
  >

This addresses what would otherwise be something of a functional
regression.  An earlier version of the interface had a dangerous
problem:  it would silently erase data outside the range it was
told to erase.  Fixing that bug turned up some folk who relied on
that unsafe behavior.  (The classic problem with interface bugs!)
Now they can get that behavior again.  If they really need it,
just specify "pad".

Øyvind Harboe 95f86e8e05 gdb: fix regression in gdb_port command
The gdb_port command can be invoked during normal execution
to report the port used for gdb, whereas it was listed as
CONFIG stage only, which caused an error when excuting
it to return the reported error.

Also in line with the grander goal of making more commands
available during all "modes" (perhaps retiring config mode),
there is no particular reason to limit gdb_port to the
config stage.

Regression was introduced in:

David Brownell b3bf1d12b2 streamline and document helptext mode displays
Most commands are usable only at runtime; so don't bother saying
that, it's noise.  Moreover, tokens like EXEC are cryptic.  Be
more clear: highlight only the commands which may (also) be used
during the config stage, thus matching the docs more closely.
There are

 - Configuration commands (per documentation)
 - And also some commands that valid at *any* time.

Update the docs to note that "help" now shows this mode info.

This also highlighted a few mistakes in command configuration,
mostly commands listed as "valid at any time" which shouldn't
have been.  This just fixes ones I noted when sanity testing.

It's probably good to phase out such usage, given the number of bugs

these even though such usage is actually legal.
