| H A D | tpm_tis.h | bbadfb2e Fri Apr 14 22:07:53 GMT 2023 Ninad Palsule <ninad@linux.ibm.com> tpm: Extend common APIs to support TPM TIS I2C
Qemu already supports devices attached to ISA and sysbus. This drop adds
support for the I2C bus attached TPM devices.
This commit includes changes for the common code.
- Added support for the new checksum registers which are required for
the I2C support. The checksum calculation is handled in the qemu
common code.
- Added wrapper function for read and write data so that I2C code can
call it without MMIO interface.
The TPM TIS I2C spec describes in the table in section "Interface Locality
Usage per Register" that the TPM_INT_ENABLE and TPM_INT_STATUS registers
must be writable for any locality even if the locality is not the active
locality. Therefore, remove the checks whether the writing locality is the
active locality for these registers.
