commit a545d910afa121beafb9a12ee6cad546792f70f5 Author: Furquan Shaikh furquan@chromium.org Date: Thu Sep 29 19:37:49 2016 -0700
Revert "soc/intel/apollolake: Add pmc_ipc device support"
This reverts commit 28821dbb2261267462a7e9b0cc1c23b51af2d3ee. (https://review.coreboot.org/16649)
This change causes the kernel to boot really slow. Maybe there is an interrupt storm that prevents the kernel from making any progress. Reverting until the proper kernel dependency is met.
BUG=chrome-os-partner:57364 BRANCH=None TEST=Kernels boots to prompt fine on DVT.
