tpm: acpi: Add support for TPM PIRQ
With SPI TPMs there is no SERIRQ for interrupts, instead it is a PIRQ based interrupt. The TCG PC Client Platform TPM Profile Specification says it must be active low and shared. This can be enabled with the CONFIG_TPM_PIRQ option that will specify the interrupt vector to report for the TPM. BUG=chrome-os-partner:40635 BRANCH=none TEST=verify TPM interrupt functionality in /proc/interrupts on glados Change-Id: Iad3ced213d1fc5380c559f50c086206dc9f22534 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: abdd0b8ecdf51ff32ed8bfee0823bbc30d5d3d49 Original-Change-Id: If7d22dfcfcab95dbd4c9edbd8674fc8d948a62d2 Original-Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/304133 Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/12147 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
