From 6408ada4a20ca2811de8a158d0579b421f56d8fe Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Thu, 12 Nov 2020 17:33:00 +0100 Subject: soc/intel/xeon_sp: move get_iiostack_info() to a common place All this function does is looping over IIO stacks in the FSP HOB. The only 'SOC/FSP specific' thing is the way to detect if the stack is an IIO stack so add a callback to determine this.
