Add the necessary files and changes to support vboot.
TEST=Build and run on Galileo Gen2 with a SparkFun CryptoShield
1. Obtain and install a SparkFun CryptoShield.
https://www.sparkfun.com/products/13183
2. Edit src/mainboard/intel/galileo/Kconfig to select
VBOOT_WITH_CRYPTO_SHIELD
3. Use make menuconfig to update the config values and select a
payload that will fit. I used SeaBIOS which does not boot.
4. Build coreboot
5. Use the command file below to generate the signed coreboot image.
6. Flash build/coreboot.rom onto the Galileo board
7. The test is successful if verstage detects that it needs recovery
after Phase 1. This is expected because the image does not contain
the GBB section.
8. Flash build/coreboot.signed.bin onto the Galileo board
9. The test is successful if verstage reaches Phase 4 and selects SLOT
A to load the rest of the files.

# The necessary tools were built and installed using the following
commands:
#
# pushd 3rdparty/vboot
# make
# sudo make install
# popd
#
# The keys were made using the following command
#
# 3rdparty/vboot/scripts/keygeneration/create_new_keys.sh \
# --4k --4k-root --output $PWD/keys
#
#
# Create the GBB area blob
#
gbb_utility -c 0x100,0x1000,0x7ce80,0x1000 gbb.blob
#
# Add the empty GBB to the coreboot.rom image

------------------------------------------------------------------------------- coreboot README ------------------------------------------------------------------------------- coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload. With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required. coreboot was formerly known as LinuxBIOS. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot. See http://www.coreboot.org/Payloads for a list of supported payloads. Supported Hardware ------------------ coreboot supports a wide range of chipsets, devices, and mainboards. For details please consult: * http://www.coreboot.org/Supported_Motherboards * http://www.coreboot.org/Supported_Chipsets_and_Devices Build Requirements ------------------ * make * gcc / g++ Because Linux distribution compilers tend to use lots of patches. coreboot does lots of "unusual" things in its build system, some of which break due to those patches, sometimes by gcc aborting, sometimes - and that's worse - by generating broken object code. Two options: use our toolchain (eg. make crosstools-i386) or enable the ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case). * iasl (for targets with ACPI support) Optional: * doxygen (for generating/viewing documentation) * gdb (for better debugging facilities on some targets) * ncurses (for 'make menuconfig' and 'make nconfig') * flex and bison (for regenerating parsers) Building coreboot ----------------- Please consult http://www.coreboot.org/Build_HOWTO for details. Testing coreboot Without Modifying Your Hardware ------------------------------------------------ If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU. Please see http://www.coreboot.org/QEMU for details. Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
