*.public - public keys for the OLPC security mechanism.  When an OLPC 
system is configured for secure mode, OFW will only boot images that 
have been signed by an OLPC private key.  There are separate keys for 
bootable images, firmware update images, and OS update images.

verify.img - this is a binary module that contains the crypto code that 
processes the aforementioned keys.  It is compiled from C source at 
http://dev.laptop.org/git?p=bios-crypto .  That code is recompiled 
infrequently and binary versions are released at 
http://dev.laptop.org/pub/firmware/crypto/

usb8388.bin - this is the firmware for ARM microprocessor that controls 
the wireless network module.  OFW needs it to do wireless network access.

ec_vXXX.img - the firmware for the 8042 embedded controller that 
controls the system power and handles the keyboard and mouse.  It lives 
in the same SPI FLASH ROM as OFW.

Thanks, I just checked in a new copy of the Makefile with an explicit 
rule for random.o

Yes, it is safe.  The "no-stack-protector" flag is needed for some 
distributions that have different default compilation options.  If your 
compiler doesn't support the flag, the flag is not needed.
