2017-03-28vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by defaultJulius Werner
The virtualized developer switch was invented five years ago and has been used on every vboot system ever since. We shouldn't need to specify it again and again for every new board. This patch flips the Kconfig logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the latter for Lumpy which seems to have been omitted incorrectly, and hide it from menuconfig since it's a hardware parameter that shouldn't be configurable.) Since almost all our developer switches are virtual, it doesn't make sense for every board to pass a non-existent or non-functional developer mode switch in the coreboot tables, so let's get rid of that. It's also dangerously confusing for many boards to define a get_developer_mode() function that reads an actual pin (often from a debug header) which will not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set. Therefore, this patch removes all those non-functional instances of that function. In the future, either the board has a physical dev switch and must define it, or it doesn't and must not. In a similar sense (and since I'm touching so many board configs anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC. Instead, it should just be assumed by default whenever a Chrome EC is present in the system. This way, it can also still be overridden by menuconfig.

2017-03-16mainboard/intel/galileo: Add vboot supportLee Leahy
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. commands: gbb_utility -c 0x100,0x1000,0x7ce80,0x1000 gbb.blob dd conv=fdatasync ibs=4096 obs=4096 count=1553 \ if=build/coreboot.rom of=build/coreboot.signed.rom dd conv=fdatasync obs=4096 obs=4096 seek=1553 if=gbb.blob \ of=build/coreboot.signed.rom dd conv=fdatasync ibs=4096 obs=4096 skip=1680 seek=1680 \ count=368 if=build/coreboot.rom of=build/coreboot.signed.rom gbb_utility \ --set --hwid='Galileo' \ -r $PWD/keys/recovery_key.vbpubk \ -k $PWD/keys/root_key.vbpubk \ build/coreboot.signed.rom 3rdparty/vboot/scripts/image_signing/sign_firmware.sh \ build/coreboot.signed.rom \ $PWD/keys \ build/coreboot.signed.rom Change-Id: I02eb0ef647cd34c13a5fe8be0bdbe1bb38524d0c Signed-off-by: Lee Leahy <leroy.p.leahy@intel.com> Reviewed-on: https://review.coreboot.org/18821 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
