Vadim Bendebury f5ef699f40 tpm2: implement and use pcr_extend command
TPM PCRs are used in Chrome OS for two purposes: to communicate
crucial information from RO firmware and to protect FW and kernel
rollback counters from being deleted.

As implemented in a TPM1 compatible way, the PCR extension command
requires a prebuilt digest to calculate a new PCR value.

TPM2 specification introduces a PCR_Event command, where the TPM
itself calculates the digest of an arbitrary length string, and then
uses the calculated digest for PCR extension. PCR_Event could be a
better option for Chrome OS, this needs to be investigated separately.

BRANCH=none
BUG=chrome-os-partner:50645
TEST=verified that the two PCRs are successfully extended before the
     RW firmware is called.

Vadim Bendebury 7ee057c700 tpm2: use pcr0 dependent nvram space policy definitions
The TPM2 specification allows defining NV ram spaces in a manner
that makes it impossible to remove the space until a certain PCR is in
a certain state.

This comes in handy when defining spaces for rollback counters: make
their removal depend on PCR0 being in the default state. Then extend
PCR0 to any value. This guarantees that the spaces can not be deleted.

Also, there is no need t create firmware and kernel rollback spaces
with different privileges: they both can be created with the same set of
properties, the firmware space could be locked by the RO firmware, and
the kernel space could be locked by the RW firmware thus providing
necessary privilege levels.

BRANCH=none
BUG=chrome-os-partner:50645, chrome-os-partner:55063
TEST=with the rest of the patches applied it is possible to boot into
      Chrome OS maintaining two rollback counter spaces in the TPM NV
      ram locked at different phases of the boot process.

Vadim Bendebury bc927107a0 tpm2: avoid comparison between signed and unsigned ints
The marshaling/unmarshaling code is using integer values to represent
room left in the buffer, to be able to communicate three conditions:
positive number means there is room left in the buffer, zero means
that the exact amount of data in the buffer was unmarshaled and
negative value means that the result of the operation did not fit into
the buffer.

The implementation is wrong though, as it compares directly signed and
unsigned values, which is illegal, as signed values get promoted to
unsigned by the compiler.

This patch changes the marshaling code to use size_t for the size, and
use zero as marshaling failure indication - after all the buffer where
the data is marshaled to should definitely be large enough, and it is
reasonable to expect at least some room left in it after marshaling.

The unmarshaling situation is different: we sure want to communicate
errors to the caller, but do not want to propagate error return values
through multiple layers. This patch keeps the size value in int, but
checks if it is negative separately, before comparing with positive
values.

Aaron Durbin b72c67b713 soc/intel/apollolake: set gpio interrupt polarity in ITSS
For APIC routed gpios, set the corresponding interrupt polarity
for the associated IRQ based on the gpio pad's invert setting.
This allows for the APIC redirection entries to match the hardware
active polarity once the double inversion takes place to meet
apollolake interrupt triggering constraints.

Aaron Durbin 1318e88352 soc/intel/apollolake: add initial ITSS support
The interrupt and timer subsystem (ITSS) sits between the APIC
and the other logic blocks. It only supports positive polarity
events, but there's a polarity inversion setting for each IRQ such
that it can pass the signal on to the APIC according to the
expected APIC redirection entry values. This support is needed
in order for the platform/board to set the expected interrupt
polarity into the APIC for gpio signals.

Internally, apollolake routes its interrupts as active high.
This includes SCI, SMI, and ACPI. Therefore, provide helper
macros such that the user can describe an interrupt's active
high/low polarity more easily. It helps for readability when
one is comparing gpio configuration next to APIC configuration
in different files. Additionally, the gpio APIC macros always
use a LEVEL trigger in order to let the APIC handle the
filtering of the IRQ on its own end.

if set from BIOS. As per ACPI spec _GPE is defined as the Named

has no mechanism to acheive the same.

When using "make menuconfig", if "add pxe rom" is selected, then

This problem seems to be due to the use of the 'optional' Kconfig

Vadim Bendebury 10ea104476 vboot2: tpm2 factory initialization.
This patch adds a TPM2 specific path in the vboot2 initialization
sequence when the device is turned on in the factory for the first
time, namely two secure NVRAM spaces are created, with different
access privileges.

The higher privilege space can be modified only be the RO firmware,
and the lower privilege space can be modified by both RO and RW
firmware.

The API is being modified to hide the TPM implementation details from
the caller.

Some functions previously exported as global are in fact not used
anywhere else, they are being defined static.

BRANCH=none
BUG=chrome-os-partner:50645
TEST=when this code is enabled the two secure spaces are successfully
     created during factory initialization.

squashed:

mock tpm: drop unused functions

safe_write() and safe_define_space() functions are defined in
secdata_mock.c, but not used in mocked TPM mode.

The actual functions have been redefined as static recently and their
declarations were removed from src/include/antirollback.h, which now
causes compilation problems when CONFIG_VBOOT2_MOCK_SECDATA is
defined.

Dropping the functions from secdata_mock.c solves the problem.

BRANCH=none
BUG=none
TEST=compilation in mock secdata mode does not fail any more.

Lin Huang e3d78b82a7 rockchip/rk3399: calculate clocks based on parent clock speed
Currently aclkm pclkdbg atclk clocks use apll_l as a parent, but the
apll_l frequency may change in firmware, so we need to caculate the div
value based on the apll_l frequency.
