From 0613ccbd1357b1f6aecab27a2e72dde328d36f6d Mon Sep 17 00:00:00 2001 From: Maurice Ma Date: Mon, 17 Oct 2016 10:48:04 -0700 Subject: [PATCH] CorebootPayloadPkg/PciHostBridgeLib: Fix the wrong PCI resource limit The current PCI resource limit calculation in CorebootPayloadPkg PciHostBridgeLib is wrong. Adjusted it to match the PciHostBridge driver's expectation.
