This is the preliminary v05 TPM driver from Infineon. With a wrapper layer added to auto detect v03 and v05 chips. This is a version that just work. Cleanup will start after the initial push.
BUG=chromium-os:10497
TEST=Manual
Build
1. build a compatible lib first
emerge-tegra2_seaboard vboot_reference-firmware
2. use MAKEALL script to check all cfg
CROSS_COMPILE=armv7a-cros-linux-gnueabi- VBOOT=/build/tegra2_seaboard/usr ./MAKEALL chromeos
3. check result. 25 passed, no warning, no error
u-boot command
1. build a compatible version
USE-debug VBOOT_DEBUG=1 emerge-tegra2_seaboard -av vboot_reference-firmware chromeos-u-boot-next
2. flash it using proper tools
[board specific]
3. reset system and boot into command prompt
4. test with cros_tpm_test command sets:
cros_tpm_test enable
cros_tpm_test fast_enable
