+FastBoot  Version  0.4
+----------------------
+
+The fastboot protocol is a mechanism for communicating with bootloaders
+over USB.  It is designed to be very straightforward to implement, to
+allow it to be used across a wide range of devices and from hosts running
+Linux, Windows, or OSX.
+
+
+Basic Requirements
+------------------
+
+* Two bulk endpoints (in, out) are required
+* Max packet size must be 64 bytes for full-speed and 512 bytes for 
+  high-speed USB
+* The protocol is entirely host-driven and synchronous (unlike the
+  multi-channel, bi-directional, asynchronous ADB protocol)
+
+
+Transport and Framing
+---------------------
+
+1. Host sends a command, which is an ascii string in a single
+   packet no greater than 64 bytes.
+
+2. Client response with a single packet no greater than 64 bytes.
+   The first four bytes of the response are "OKAY", "FAIL", "DATA", 
+   or "INFO".  Additional bytes may contain an (ascii) informative
+   message.
+
+   a. INFO -> the remaining 60 bytes are an informative message
+      (providing progress or diagnostic messages).  They should 
+      be displayed and then step #2 repeats
+
+   b. FAIL -> the requested command failed.  The remaining 60 bytes 
+      of the response (if present) provide a textual failure message 
+      to present to the user.  Stop.
+
+   c. OKAY -> the requested command completed successfully.  Go to #5
+
+   d. DATA -> the requested command is ready for the data phase.
+      A DATA response packet will be 12 bytes long, in the form of
+      DATA00000000 where the 8 digit hexidecimal number represents
+      the total data size to transfer.
+
+3. Data phase.  Depending on the command, the host or client will 
+   send the indicated amount of data.  Short packets are always 
+   acceptable and zero-length packets are ignored.  This phase continues
+   until the client has sent or received the number of bytes indicated
+   in the "DATA" response above.
+
+4. Client responds with a single packet no greater than 64 bytes.  
+   The first four bytes of the response are "OKAY", "FAIL", or "INFO".  
+   Similar to #2:
+
+   a. INFO -> display the remaining 60 bytes and return to #4
+   
+   b. FAIL -> display the remaining 60 bytes (if present) as a failure
+      reason and consider the command failed.  Stop.
+
+   c. OKAY -> success.  Go to #5
+
+5. Success.  Stop.
+
+
+Example Session
+---------------
+
+Host:    "getvar:version"        request version variable
+
+Client:  "OKAY0.4"               return version "0.4"
+
+Host:    "getvar:nonexistant"    request some undefined variable
+
+Client:  "OKAY"                  return value ""
+
+Host:    "download:00001234"     request to send 0x1234 bytes of data
+
+Client:  "DATA00001234"          ready to accept data
+
+Host:    < 0x1234 bytes >        send data
+
+Client:  "OKAY"                  success
+
+Host:    "flash:bootloader"      request to flash the data to the bootloader
+
+Client:  "INFOerasing flash"     indicate status / progress
+         "INFOwriting flash"
+         "OKAY"                  indicate success
+
+Host:    "powerdown"             send a command
+
+Client:  "FAILunknown command"   indicate failure
+
+
+Command Reference
+-----------------
+
+* Command parameters are indicated by printf-style escape sequences.
+
+* Commands are ascii strings and sent without the quotes (which are
+  for illustration only here) and without a trailing 0 byte.
+
+* Commands that begin with a lowercase letter are reserved for this
+  specification.  OEM-specific commands should not begin with a 
+  lowercase letter, to prevent incompatibilities with future specs.
+
+ "getvar:%s"           Read a config/version variable from the bootloader.
+                       The variable contents will be returned after the
+                       OKAY response.
+
+ "download:%08x"       Write data to memory which will be later used
+                       by "boot", "ramdisk", "flash", etc.  The client
+                       will reply with "DATA%08x" if it has enough 
+                       space in RAM or "FAIL" if not.  The size of
+                       the download is remembered.
+
+  "verify:%08x"        Send a digital signature to verify the downloaded
+                       data.  Required if the bootloader is "secure"
+                       otherwise "flash" and "boot" will be ignored.
+
+  "flash:%s"           Write the previously downloaded image to the
+                       named partition (if possible).
+
+  "erase:%s"           Erase the indicated partition (clear to 0xFFs)
+
+  "boot"               The previously downloaded data is a boot.img
+                       and should be booted according to the normal
+                       procedure for a boot.img
+
+  "continue"           Continue booting as normal (if possible)
+
+  "reboot"             Reboot the device.
+
+  "reboot-bootloader"  Reboot back into the bootloader.
+                       Useful for upgrade processes that require upgrading
+                       the bootloader and then upgrading other partitions
+                       using the new bootloader.
+
+  "powerdown"          Power off the device.
+
+
+
+Client Variables
+----------------
+
+The "getvar:%s" command is used to read client variables which
+represent various information about the device and the software
+on it.
+
+The various currently defined names are:
+
+  version             Version of FastBoot protocol supported.
+                      It should be "0.3" for this document.
+
+  version-bootloader  Version string for the Bootloader.
+
+  version-baseband    Version string of the Baseband Software
+
+  product             Name of the product
+
+  serialno            Product serial number
+
+  secure              If the value is "yes", this is a secure
+                      bootloader requiring a signature before
+                      it will install or boot images.
+
+Names starting with a lowercase character are reserved by this
+specification.  OEM-specific names should not start with lowercase
+characters.
