this never panned out and there are enough mistakes in
the code that probably nobody used this.
Use the tcl server and implement a standalone http
app instead works fine.

Add comments to assembly flash loader for STM32. Add tiny improvement in
size of the algorithm (40 vs 48 bytes) and tiny speed improvement (~1.5%,
as time is wasted on waiting for end of operation anyway).

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.

If the CPU crashed at some point, poll will discover this.
Previously the poll fn would clear the error and print a warning,
rather than propagating the error.
The new behavior is to report the error back up, but still
clear the error.

This patch introduces support for Cortex A8 based Freescale i.MX51 CPU. This CPU
has the Debug Access Port located at a different address (0x60008000) than TI
OMAP3 series of CPUs.

This patch adds function called "dap_detect_debug_base()", which should be
called to get location of the ROM Table. By walking ROM Table, it's possible to
discover the location of DAP.
Sadly, some CPUs misreport this value, therefore I had to introduce an fixup
table, which will be used in case such CPU is detected.

So far most of the people have been using existing ARM966E in the
place of ARM946E, because they have practically the same scan chains.
However, ARM946E has caches, which further complicates JATG handling
via scan-chain. this was preventing single-stepping for ARM946E when
SW breakpoints are used.
This patch thus introduces :
1) Correct cache handling on memory write
2) Possibility to flush whole cache and turn it off during debug, or
just to flush affected lines (faster and better)
3) Correct SW breakpoint handling and correct single-stepping
4) Corrects the bug on CP15 read and write, so CP15 values
are now correctly R/W
measure_clk indicates ca. 3-4MHz, so 1MHz should be safe.
Added self_test proc used to test that rclk worked.

Provide new helper proc that can set up either an SWD or JTAG DAP
based on the transport which is in use -- mostly for SWJ-DP.
Also update some SWJ-DP based chips/targets to use it. The goal
is making SWD-vs-JTAG transparent in most places. SWJ-DP based chips
really need this flexible configuration to cope with debug adapters
that support different transports, without needing new target configs
for each transport or adapter.
For JTAG-DP, callers will use "jtag newtap" directly, as today; only
one chip-level transport option exists.
For SW-DP (e.g. LPC1[13]xx or EFM32, they'll use "swd newdap" directly
(part of an upcoming SWD transport patch). Again, only one transport
option exists, so hard-wiring is appropriate there.

When usng gdb pipes we need to keep openocd output at a minimum,

Firstly this patch fixes the build issue, but it also disables support
for named pipes under Windows. Windows does not support posix named
pipes.
A cross-platfom access layer will need creating before support can be
enabled again.

depending on whether the connection is over a socket
or pipe, the read is done differently.
pipes can return -1 when writing 0 bytes, make 0 byte
writes a successful no-op. 0 byte writes falls out
naturally of tcl server code.

There is an explicit command "log_output" that can
