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 MAX32650/1/2
+
+This BSP is for working with the Analog Devices
+[MAX32650](https://www.analog.com/en/products/max32650.html),
+[MAX32651](https://www.analog.com/en/products/max32651.html) and
+[MAX32652](https://www.analog.com/en/products/max32652.html)
+microcontrollers.  The following boards are supported:
+ * [MAX32650EVKIT](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32650-evkit.html)
+ * [MAX32650FTHR](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32650fthr.html)
+ * [MAX32651EVKIT](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/max32651-evkit.html) (Secure Bootloader)
+
+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 microcontrollers utilize 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
+
+### MAX32650 and MAX32652
+
+The default flashing behavior in this BSP for the MAX32650 and MAX32652 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.
+
+Both the Evaluation Kit and Feather boards are 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.
+
+### MAX32651
+
+The MAX32651 features an integrated secure bootloader which requires the
+application image be signed prior to flashing.  Both the Makefile and CMake
+scripts account for this signing automatically when building for the
+MAX32651EVKIT.
+
+To flash the signed image, the MSDK's OpenOCD variant must be used.  To flash
+the MAX32651EVKIT please install the bundled MSDK, and utilize the `flash-msdk`
+and `<target>-msdk` rule and target.

+# 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.
