2013-09-25hla: cleanup read/write apiSpencer Oliver
This is the first part in moving the adapter specific api back into the driver. The next task is to also move the hla read/write buffer size handling.

2013-08-29stlink: Add workaround for intermittent FW info retrieval failureAndrey Smirnov
It appears that on some host USB configurations(2012 MacBook Air) multiple restarts of openocd tool cause the FW on STLINKv2 dongle to go into a weird state in which it will no longer respond to STLINK_GET_VERSION command. This patch adds code that, if said request fails for the first time, attempts to reset the device and retry to initialize it and obtain FW information one more time.

2013-08-07stlink: add SWO tracing supportAndrey Yurovsky
Enable reading the SWO trace output via STLinkv2 dongles that support it. This adds an optional initialization parameter "trace" with which the user specifies a destination file where SWO trace output is appended as it comes in as well as the trace module's source clock rate. STLink will be configured for a 2MHz SWO data rate (STLink's highest supported rate) if the source clock is > 2MHz, otherwise the source clock is used as the data rate directly. For example: trace swo.log 168000000 If "trace" is specified with a usable file path, the stlink_usb driver will attempt to configure and read SWO trace data as follows: - on _run(), the target's TPI and TMI are configured and the STLinkv2 is told to enable tracing. Only generic ARM TPI and TMI registers are configured, any MCU-specific settings (ex: pin routing) are the responsibility of the target firmware. The configuration applied is based on the STLinkv2's capabilities (UART emulation). - on _v2_get_status(), the trace data (if any) is fetched from the STLink after the target status is checked and the target is found to be running. - on _halt(), the STLink is told to disable tracing. When fetching trace data, the entire trace frame is written to the output file and that data is flushed. An external tool may be used to parse the trace data into a more human-readable format. Tested on ARM Cortex M4F and M3 MCUs (STM32F407 and STM32L152).
