It seems there is some problem with the rewrite of the TPM: https://review.coreboot.org/q/commit:c07f8fbe6fd13e4245da71574b52b47e9733db84 Workaround: Comment out both lines that has TPM on src/maoinbaord/lenovo/t420/Kconfig In src/mainboard/lenovo/t420/devicetree.cb you need to remove three lines: the "chip drivers/pc80/tpm" line and the other two lines just below ("device pnp 0c31.0 on end" and "end")
