From fd3df8e24b69c4871932c03f8a0b13c73dac4ca7 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Wed, 27 Jan 2021 12:38:42 +0100 Subject: sb/intel/ibexpeak: Drop invalid ME finalisation function Was copied from bd82x6x and none of the PCI IDs matches that of Ibex Peak (PCI_DID_INTEL_IBEXPEAK_HECI1 = 0x3b64). Remove the code. This allows dropping the me_8.x.c dependency, which never made sense.
