The patch below fixes step <address> on mips_m4k.
Spencer Oliver <spen@spen-soft.co.uk>:
The current code is used on all other arch's - is
there a underlying issue with those aswell ?
I don't think dsp563xx_once_read_register() would ever
be called with len==0, but it would have been broken in
that case.

Problem is, trying to print "Hello, world!\n" just prints endless H's, because r1 is never incremented.
One way to fix it would be to add a "++" after "r1".
Fix a bunch of typos.
Most are in code comments, so nothing should break. UNKOWN_COMMAND and
CMD_UNKOWN are not used elsewhere, so correcting the spelling should
also not break anything.
only flush write queue just before waiting for more data,
rather than when fetching more data from the buffer.

Found by inspection: the correct thing in the context is to use
usleep() rather than jtag_sleep(). Relates to JTAG over TCP/IP
only.

short sleeps are handled via usleep, longer sleeps we round up
to nearest ms.
There was a bug in jtag_sleep() in that it would round *down*
to nearest ms, thus making all <1ms sleeps 0. Found by inspection
rather than symptom.

Soft breakpoints are currently broken if the MMU is enabled due to incorrect
cache flushing. Until this is fixed, force the use of hardware breakpoints.

as said in the datasheet Section 3.3.2 Organization of buffers
All buffers are big enough to hold 2 KByte of data.

this will allow us to use multiple jlink at the same time as when
the USB-Address is specified the PID change from 0x0101 to
(0x101 + usb_adress)

The default pid of the segger is 0x0101
But when you change the USB Address it will also
pid = ( usb_address > 0x4) ? 0x0101 : (0x101 + usb_address)

This patch fix a possible read buffer overflow in ft2232_execute_queue.
Also the correct read queue size for libftdi and libftd2xx was added and
and tested.
In function ft2232_write a uninitialized value was initialized because we
don't know if this value was set in the ftdi api call.

This patch add rudimentary gdb support. The gdb register list
order is corrected. All registers are now 32bit width. Events are
send to signalize gdb the current target status. Resume and step
function was corrected to consider a modified pc register. Read/write
memory now support L memory type, this means a memory with alternating
y/x memory words. The memspace variable, used by gdb, is now observed
before a default memory access is initiated. Dummy functions for breakpoint
and watchpoint are added.
Use the http protocol for git2cl module, as it makes it easier for the
firewall safe mirror to keep all submodules firewall safe.

This patch tries to make some order in "apsel" mess.
"dap apsel" command was quite useless (and broken) by itself.
With this patch we can use it to select between AHB or APB memory access
(previous patch 05ab8bdb81 was somehow broken).
- moves member apsel (in struct adiv5_dap) to ap_current
- adds apsel member
this strange choice is made trying to keep coherence in "dap apsel" command
and to keep compatibility with other code (for example cortex_a8).

This patch move the dsp563xx_target_create function to the
related code block. Also the target examine function was added
and the register cache is initialized in a separate function. The
missing functionality to invalidate the x memory context on memory
writes was also added.
