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.

With the new JIMTCL, "puts" only writes to stdout.
To write on telnet port too, "echo" must be used.
This patch gives to "echo" similar commandline option of "puts".

Initial support for ST SPEAr310 and for the evaluation
board EVALSPEAr310 Rev. 2.0.
Scripts are split in generic for SPEAr3xx family and
specific for SPEAr310. This should easily allow adding
new members of the family.

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.
i.MX51 configuration file based on OMAP3 configuration file and an email from
Alan Carvalho de Assis <acassis@gmail.com>.

Implement autodetection of debug base. Also, implement a function solving
various hardware quirks (like iMX51 ROM Table location bug).

This patch implements "dap_lookup_cs_component()", which allows to lookup CS

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.
