Android/Security

Firmware security for the Android and Sugar build.

• set up for signing using Firmware security,
• copy /boot/kernel and /boot/ramdisk from the Android build,
• sign the Android kernel

sign-os.sh os vmlinuz runos4.zip

• sign the Android ramdisk

sign-os.sh os initrd runrd4.zip

• make a /boot/alt directory,
• place both in /boot/alt,
• link the activation mode to the Sugar activation kernel and ramdisk,

ln -s ../runos4.zip actos4.zip
ln -s ../actrd4.zip actrd4.zip

• test booting using the O game key to select Android, or no O game key to select Sugar, using the X game key to enable security if it is not enabled.

Removes the boot menu, because the boot menu is implemented in olpc.fth, and olpc.fth is not used during secure boot.
