2013-02-02armv7m: use generic arm::core_modeSpencer Oliver
To simplify things change over to using the generic core_mode struct rather than maintaining a armv7m specific one.

2013-01-21flash: add stm32lx loader Hard Fault workaroundSpencer Oliver
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.

2013-01-21flash: reduce stm32lx loader timeoutSpencer Oliver
Waiting 20secs is a bit much excessive, we could probably reduce to 5. Change-Id: Iffb97adb99c2541a075fe78dbc88a53ddf340214 Signed-off-by: Spencer Oliver <spen@spen-soft.co.uk> Reviewed-on: http://openocd.zylin.com/1009 Tested-by: jenkins
2013-01-21flash: cleanup stm32lx driverSpencer Oliver
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.

2012-12-30flash: stm32lx fallback to slow memory writes when no working areaSpencer Oliver
The current stm32lx driver will fail if no working area is provided - fallback to using slow writes if this is the case.

Working area pointers shouldn't be re-used, so there's no point in storing them in the flash bank struct. Make all such pointers local.

2012-07-30flash: reduce code duplication in stm32 flash probeAndreas Fritiofson
Remove a lot of the repetitive code in stm32f1x flash probe by converting the large if-selector to a switch, moving the common checks outside it and concentrating the failure handling to a single point. Do the same with stm32f2x and stm32lx for consistency.
