2015-01-15stlink: add reconfigurable speed supportSpencer Oliver
The ability to change the speed has been added to firmware versions J22 and above. Any attempt to change on earlier versions will be ignored without error, as the existing code does. For supported firmware versions the driver will attempt to get as close as possible to supported speeds (never higher). The default stlink speed on power up is 1.8MHz. The driver will now also print supported clocl speeds during init.

2014-11-24flash/nor/lpcspifi.c: fix bug that prevented clean reset after flash writeAnders
After SPI flash was written by the assembly language stub, the last SPI command was not terminated by raising CS. This left the SPI device in a hung state that prevented the flash from being read by the M4 SPIFI controller, even after the M4 was fully reset. To access the flash via SPIFI, it was necessary to completely power cycle the board. This fix adds the missing instructions to raise CS and terminate the SPI command after the last byte. This allows the M4 to be resumed or reset cleanly after flashing. The SPIFI memory is now immediately accessable at address 0x1400 0000 after flashing is complete.

2014-10-06at91samd: fix protect, add EEPROM and boot commandsAndrey Yurovsky
There were two problems with the _protect() feature: 1. The address written was off by a factor of two because the address register takes 16-bit rather than 8-bit addresses. As a result the wrong sectors were (un)protected with the protect command. This has been fixed. 2. The protection settings issued via the lock or unlock region commands don't persist after reset. Making them persist requires modifying the LOCK bits in the User Row using the infrastructure described below. The Atmel SAMD2x MCUs provide a User Row (the size of which is one page). This contains a few settings that users may wish to modify from the debugger, especially during production. This change adds commands to inspect and set: - EEPROM size, the size in bytes of the emulated EEPROM region of the Flash. - Bootloader size, the size in bytes of the protected "boot" section of the Flash. This is done by a careful read-modify-write of the special User Row page, avoiding erasing when possible and disallowing the changing of documented reserved bits. The Atmel SAMD20 datasheet was used for bit positions and descriptions, size tables, etc. and testing was done on a SAMD20 Xplained Pro board. It's technically possible to store arbitrary user data (ex: serial numbers, MAC addresses, etc) in the remaining portion of the User Row page (that is, beyond the first 64 bits of it). The infrastructure used by the eeprom and bootloader commands can be used to access this as well, and this seems safer than exposing the User Row as a normal Flash sector that openocd understands due to the delicate nature of some of the data stored there.

2014-10-06at91samd: add erase/secure commands, minor fixAndrey Yurovsky
Reference code for the SAMD2x disables caching in the NVM controller when issuing NVM commands. Let's do this as well to be consistent and safer. Add a "chip-erase" for the Atmel SAMD targets that issues a complete Chip Erase via the Device Service Unit (DSU). This can be used to "unlock" or otherwise unbrick a chip that can't be halted or inspected, allowing the user to reflash with new firmware. Add a "set-security" command which issues an SSB. Once that's done and the device is power-cycled, the flash cannot be written to until a "chip-erase" is issued. The chip-erase cannot be issued by openocd at this time because the device will not respond to a request for the DAP IDCODE.
