From 6d5e10c05d99c475e63bbe95012066f9c585cfb3 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Wed, 14 Mar 2018 19:57:16 -0700 Subject: [PATCH] soc/intel/apollolake and mainboards: Use pcie_rp_clkreq_pin array This change uses an array pcie_rp_clkreq_pin for accepting CLKREQ# from mainboards instead of defining a separate property for each root port. This allows us to use memcpy to copy the entire array into FSP params as well as new properties for PCIe root ports can be added as arrays in future CLs.
