BSP Cleanup

- Added MSDK flash rules for CMake
 - Removed partial IAR support. Uniform GCC support across MAX32 parts
 - Updated build scripts for correctly signing the MAX32651
 - Added README files for the BSPs to describe flashing and limitiations

+# Analog Devices MAX78002
+
+This BSP is for working with the Analog Devices
+[MAX78002](https://www.analog.com/en/products/max78002.html) AI microcontroller.
+The following boards are supported:
+ * [MAX78002EVKIT](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max78002evkit.html)
+
+This part family leverages the Maxim Microcontrollers SDK (MSDK) for the device
+interfaces and hardware abstraction layers. This source code package is fetched
+as part of the get-deps script.
+
+The microcontroller utilizes the standard GNU ARM toolchain.  If this toolchain
+is not already available on your build machine, it can be installed by using the
+bundled MSDK installation.  Details on downloading and installing can be found
+in the [User's Guide](https://analogdevicesinc.github.io/msdk//USERGUIDE/).
+
+## Flashing
+
+The default flashing behavior in this BSP is to utilize JLink.  This can be done
+by running the `flash` or `flash-jlink` rule for Makefiles, or the
+`<target>-jlink` target for CMake.
+
+The Evaluation Kit is shipped with a CMSIS-DAP compatible debug probe. However,
+at the time of writing, the necessary flashing algorithms for OpenOCD have not
+yet been incorporated into the OpenOCD master branch.  To utilize the provided
+debug probes, please install the bundled MSDK package which includes the
+appropriate OpenOCD modifications.   To leverage this OpenOCD instance, run the
+`flash-msdk` Makefile rule, or `<target>-msdk` CMake target.
