default n
help
Enable this option to enable LPC TPM support in coreboot.
If unsure, say N.

hex
default 0xfed40000
depends on LPC_TPM
help
This can be used to adjust the TPM memory base address.
The default is specified by the TCG PC Client Specific TPM
Interface Specification 1.2 and should not be changed unless
the TPM being used does not conform to TPM TIS 1.2.

help
This can be used to specify a PIRQ to use instead of SERIRQ,
which is needed for SPI TPM interrupt support on x86.
config TPM_INIT_FAILURE_IS_FATAL
bool
default n
depends on LPC_TPM
help
What to do if TPM init failed. If true, force a hard reset,
otherwise just log error message to console.

config TPM_RDRESP_NEED_DELAY

Certain TPMs seem to need some delay when reading response
to work around a race-condition-related issue, possibly
caused by ill-programmed TPM firmware.
