Rename FunctionAttributes.h to Attributes.h, as some attributes are applicable to variables also. Add new ATTR_NOINIT attribute for global variables.

Add the beginnings of a SDP implentation to the incomplete BluetoothHost demo.

Add const attribute to the Mass Storage Host driver functions where it was applicable, but missing.

+/**

+ *  \page Page_SoftwareBootloaderStart Entering the Bootloader via Software

+ *

+ *  A common requirement of many applications is the ability to jump to the programmed bootloader of a chip

+ *  on demand, via the code's firmware (i.e. not as a result of any physical user interaction with the

+ *  hardware). This might be required because the device does not have any physical user input, or simply

+ *  just to streamline the device upgrade process on the host PC.

+ *

+ *  The following C code snippet may be used to enter the bootloader upon request by the user application.

+ *  By using the watchdog to physically reset the controller, it is ensured that all system hardware is

+ *  completely reset to their defaults before the bootloader is run. This is important; since bootloaders

+ *  are written to occupy a very limited space, they usually make assumptions about the register states based

+ *  on the default values after a hard-reset of the chip.

+ *

+ *  \code

+ *  #include <avr/wdt.h>

+ *  #include <avr/io.h>

+ *  #include <util/delay.h>

+ *

+ *  #include <LUFA/Common/Common.h>

+ *  #include <LUFA/Drivers/USB/USB.h>

+ *

+ *  uint32_t Boot_Key ATTR_NO_INIT;

+ *

+ *  #define MAGIC_BOOT_KEY            0xDC42ACCA

+ *  #define BOOTLOADER_START_ADDRESS  ({FLASH_SIZE_BYTES} - {BOOTLOADER_SEC_SIZE_BYTES})

+ *  

+ *  int Bootloader_Jump_Check(void) ATTR_INIT_SECTION(3);

+ *  int Bootloader_Jump_Check(void)

+ *  {

+ *      // If the bootloader key is correct, clear it and jump to the bootloader

+ *      if (Boot_Key == MAGIC_BOOT_KEY)

+ *      {

+ *          Boot_Key = 0;

+ *          ((void (*)(void))BOOTLOADER_START_ADDRESS)(); 

+ *      }

+ *  }

+ *

+ *  void Jump_To_Bootloader(void)

+ *  {

+ *      // If USB is used, detatch from the bus and wait 2 seconds for the host to register it

+ *      USB_ShutDown();

+ *      for (uint8_t i = 0; i < 128; i++)

+ *        _delay_ms(16);

+ *

+ *      // Set the bootloader key to the magic value and force a reset

+ *      Boot_Key = MAGIC_BOOT_KEY;

+ *      wdt_enable(WDTO_250MS);

+ *      for (;;); 

+ *  }

+ *  \endcode

+ *

+ *  Note that the bootloader magic key can be any arbitrary value. The {FLASH_SIZE_BYTES} and

+ *  {BOOTLOADER_SEC_SIZE_BYTES} tokens should be replaced with the total flash size of the AVR

+ *  in bytes, and the allocated size of the bootloader section for the target AVR.

+ *
