From aec4298ccb337106fd0115b91d846a022fdf301d Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 15 Mar 2019 16:32:33 +0100 Subject: [PATCH] pci: Scale MAX_PCI_REGIONS based on CONFIG_NR_DRAM_BANKS If a platform defines CONFIG_NR_DRAM_BANKS, each DRAM bank will be added as a PCI region. The number of MAX_PCI_REGIONS therefore needs to scale with the number of DRAM banks, otherwise we will end up with too little space in the hose->regions array to store all system memory regions.
