From: Thierry Reding Date: Fri, 15 Mar 2019 15:32:33 +0000 (+0100) Subject: pci: Scale MAX_PCI_REGIONS based on CONFIG_NR_DRAM_BANKS X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=aec4298ccb337106fd0115b91d846a022fdf301d;p=u-boot.git 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.
