BUG=chrome-os-partner:2832
TEST=manual

crossystem tpm_fwver tpm_kernver
On a debug system, this will return 0x00010001 0x00010001

b64faaa7f4 Update PCR state with the state of the firmware keyblock flags too. 
I re-factored the extend call into its own module, since it doesn't necessarily
need to be couple with rollbackfirmwaresetup.

BUG=chrome-os-partner:2372
TEST=Tried emerge-x86-generic and emerge-arm-generic vboot_reference.

95c4031ce9 This is necessary to pass additional information about whether firmware A or B is being run. This change also passes the GBB directly into LoadFirmware() and LoadKernel(). 
Change-Id: I976c11c82c3d665a4feb88226e919f16c2440f60

BUG=chrome-os-partner:1657
TEST=manual - see below

make && make runtests

Then test verifying a test image in both dev mode (-b1, no key specified) and recovery mode (key specified)

build/utility/load_kernel_test -b1 ~/b/USB_images/0.11.224.0-alex/chromiumos_test_image.bin

build/utility/load_kernel_test ~/b/USB_images/0.11.224.0-alex/chromiumos_test_image.bin tests/devkeys/recovery_key.vbpubk

And make sure the firmware with this change actually boots to USB and SSD.

NOTE: u-boot-next needs to change to work with this change.  will attempt a follow-up CL with that change

2447dd256f Add a PCR extend call for measuring the dev mode boot flag. 
BUG=2083
TEST=manual

Compiled with DISABLE_ROLLBACK unset. I need help testing this change - in particular, if the PCR 0 value is actually different in dev mode off vs. dev mode on. This can be done by invoking 'tpm_pcrread -p 0' at the shell. tpm_pcrread is part of the tpm_tools package.

666802822b Change rollback interface so kernel/firmware version numbers are 
packed in the calling code rather than in rollback_index.

4abede35af Add structs for TPM NV simplification. Now uses only 2 NV spaces, one for firmware and one for kernel. 
Changed TlclRead / TlclWrite to take void* / const void* to reduce typecasts.

Much restructuring of rollback_index.c.

Fixed a version-packing bug in rollback_index.c (& --> |)

87c13d806b Added size param to VerifyData() 
Also renamed verify preamble functions, now that they do not need the
'2' at the end to differentiate them from the now-deleted original
implementation.

BUG=4501
TEST=Ran make runtests; all pass.

416f681882 This test sets the TPM to a each of a large amount of "interesting" initial states, and runs the firmware code at user level. 
This code compiles and installs using a modified ebuild (which needs to be committed after this change).
