When a device have bootloader on flash, user can set a offset that may try erase and/or override the bootloader. Add an exception to abort on any of that conditions. Signed-off-by: Gerson Fernando Budke <nandojve@gmail.com>
The SAM4L SoC have a special flash controller on the whole family. Add CalwFlash controller to allow bossac work with SAM4L SoC family. Signed-off-by: Gerson Fernando Budke <nandojve@gmail.com>
This enables SAM4L SoC family support on BOSSA. Note: SAM4L SoC family doesn't have SAM-BA boot rom. User needs compile and set all configuration to allow use any SAM-BA host like BOSSA. Signed-off-by: Gerson Fernando Budke <nandojve@gmail.com>
The SAM4L doesn't have an user interface to access the reset controller. Add Cortex-M4 NVIC reset instructions to allow use of parameter -R. Signed-off-by: Gerson Fernando Budke <nandojve@gmail.com>

Add FlashOverrideSambaError exception. This is necessary to signal to user that he is trying to erase a region where bootloader is instaled. SAM4L doesn't have ROM bootloader and sam-ba is in flash area
Add SAM4L flashcalw controller
Introduce SAM4L support
Tested with SAM4LC4B
I made an workaround to allow readChipId. I hope discuss a better approach related to that to allow proper SAM4L detection.
