Remove non-USB boards
Removes boards from boards.txt, bootloaders for those boards, and variants for those boards. As none of these boards support USB there's no reason to keep them around.

-Title: STK500v2 compatible bootloader
- Modified for Wiring board ATMega128-16MHz
-Author: Peter Fleury <pfleury@gmx.ch> http://jump.to/fleury
-Compiler: avr-gcc 3.4.5 or 4.1 / avr-libc 1.4.3
-Hardware: All AVRs with bootloader support, tested with ATmega8
-License: GNU General Public License
-
-Modified: Worapoht Kornkaewwattanakul <dev@avride.com> http://www.avride.com
-Date: 17 October 2007
-Update: 1st, 29 Dec 2007 : Enable CMD_SPI_MULTI but ignore unused command by return 0x00 byte response..
-Compiler: WINAVR20060421
-Description: add timeout feature like previous Wiring bootloader
-
-DESCRIPTION:
- This program allows an AVR with bootloader capabilities to
- read/write its own Flash/EEprom. To enter Programming mode
- an input pin is checked. If this pin is pulled low, programming mode
- is entered. If not, normal execution is done from $0000
- "reset" vector in Application area.
- Size fits into a 1024 word bootloader section
- when compiled with avr-gcc 4.1
- (direct replace on Wiring Board without fuse setting changed)
-
-USAGE:
- - Set AVR MCU type and clock-frequency (F_CPU) in the Makefile.
- - Set baud rate below (AVRISP only works with 115200 bps)
- - compile/link the bootloader with the supplied Makefile
- - program the "Boot Flash section size" (BOOTSZ fuses),
- for boot-size 1024 words: program BOOTSZ01
- - enable the BOOT Reset Vector (program BOOTRST)
- - Upload the hex file to the AVR using any ISP programmer
- - Program Boot Lock Mode 3 (program BootLock 11 and BootLock 12 lock bits) // (leave them)
- - Reset your AVR while keeping PROG_PIN pulled low // (for enter bootloader by switch)
- - Start AVRISP Programmer (AVRStudio/Tools/Program AVR)
- - AVRISP will detect the bootloader
- - Program your application FLASH file and optional EEPROM file using AVRISP
-
-Note:
- Erasing the device without flashing, through AVRISP GUI button "Erase Device"
- is not implemented, due to AVRStudio limitations.
- Flash is always erased before programming.
-
- AVRdude:
- Please uncomment #define REMOVE_CMD_SPI_MULTI when using AVRdude.
- Comment #define REMOVE_PROGRAM_LOCK_BIT_SUPPORT to reduce code size
- Read Fuse Bits and Read/Write Lock Bits is not supported
-
-NOTES:
- Based on Atmel Application Note AVR109 - Self-programming
- Based on Atmel Application Note AVR068 - STK500v2 Protocol

-//* these are used to test issues
-//* http://code.google.com/p/arduino/issues/detail?id=505
-//* Reported by mark.stubbs, Mar 14, 2011
-//* The STK500V2 bootloader is comparing the seqNum to 1 or the current sequence
-//* (IE: Requiring the sequence to be 1 or match seqNum before continuing).
-//* The correct behavior is for the STK500V2 to accept the PC's sequence number, and echo it back for the reply message.
