Spencer Oliver f54a639b28 jtag: only change state if necessary
All the other drivers will only change the state if required.
This brings all the other drivers inline with this behaviour.

The original issue relates to problems on xscale commit 7989000e09

This does need merging into the existing cortex_m logic, however at the

Spencer Oliver d631b2e5ac flash: add stm32lx loader Hard Fault workaround
An issue has been seen with the stm32lx flash driver that if a
power cycle/reset is applied after a erase, any ram loader will Hard Fault
on execution.

A similar issue is mentioned in the errata for the device.
Two solution's seem to workaround this issue:
1, Handle the exception, this means adding exception vectors to the loader
   and changing the exception address using nvic vtor register.
2. falling back to using slower direct page writes - approx 50% slower.

Using solution 1 would mean restrictions are placed on the loader location.
Solution 2 was chosen mainly as it was simpler too implement.

Handle any leading bytes upto the next 128 byte page, enabling us to safely
use the faster page write.

Rather than use a separate word/byte write to program any trailing bytes
we use a combined write function.

Use memcpy for byte writes and change loader to using bytes.

Szymon Modzelewski b9dbf569b4 flash: stm32f1x: write option bytes using the loader
Some debuggers (stlink) can't issue 16 bit writes and have to use a
loader to write flash memory.

Currently the loader is not used for option bytes, causing
stm32x_write_options to fail silently on such hardware.

Fix this by using stm32x_write_block to write option bytes as well.

Spencer Oliver 2d75ff3151 stlink: enable connect under reset
Currently if the target supports srst_nogate we wait until target assert_reset
until we get a chance to assert the srst.
However sometimes we will not get this far if the target has already failed
the initial scan.

This has been tested on stm32.

Currently if the target supports srst_nogate we wait until target assert_reset
until we get a chance to assert the srst.
However sometimes we will not get this far if the target has already failed
the jtag_examine_chain.

This has been tested on targets that support this behaviour (STM32 and STR9).

Spencer Oliver c91dbd41ba jtag: add connect_type reset_config mode flag
This adds the ability to request to the adapter how we want to connect to
the target, eg. while srst is asserted or not.

This ability can very handy for connecting to unresponsive targets.
A prerequisite is that the target supports srst_nogate.
