Without the partition name, the bootloader would have to store all
of the data until the next flash command, which potentially wastes
time.
To help the bootloader deal with the data more efficiently, we now
issue a flashing hint ("preflash:%s", partname).
"preflash:" is used to indicate that the following download
should ignore any previous "preflash:%s".

fastboot_protocol.txt used to live in bootable/bootloader/legacy
which was old, obsolete code. However, fastboot_protocol.txt is
a useful file and belongs with the fastboot code.
