back-off algorithm for polling. Double polling
interval up to 5000ms when it fails.

when polling succeeds, reset backoff.

This avoids flooding logs(as much) when working
with conditions where the target polling will fail.

Hi everyone.  I noticed some incorrect information in the user manual
regarding how the vector table is handled on the xscale, so for your
consideration, here's a short patch that corrects it, and adds a
little more detail I thought might be helpful.

The documentation states that OpenOCD does not attempt to synchronize
the vector tables in memory with those stored in the "mini instruction
cache".  In fact, on each resume it does copy from memory to the cache
all entries in the high and low tables that were not previously
defined using the 'xscale vector_table' command. (In
src/target/xscale.c, see xscale_update_vectors(), which is invoked by
xscale_resume().)  I take advantage of this during Linux boot-up.  The
extra detail describes in general terms how I do this.

Corrections, comments are of course gratefully received.

Thanks,
Mike

It is useful to know that the printed errors are *all* the
errors there were.

This is a standard FT2232 device. More info at their web page:

srst_pulls_trst is only true on some (broken) LPC2148 boards, a fact
which is already documented in doc/openocd.texi, so it shouldn't be
set unconditionally in the target tcl.

This patch was needed to reflash when an Abort exception occured very
early after reset, before OpenOCD tried to halt the CPU.

This flash driver works on more than just two chips.
(Though it does need work still, e.g. to protect more than 64K.
(On non-'3748-A0 chips where errata allow that.))

Set up more of the Luminary-specific signals, and stop cloning
a few of the JTAG defaults.  More comments too.

Still leaves the "dap info 0" bugs unresolved (presumably coupled
to this particular adapter family) where TPIU, ITM, DWT, and other
debug modules wrongly display as extra NVICs.
