Subject: [PATCH V6 3/7] PCI: tegra: Remove PCI_REASSIGN_ALL_BUS flag for Tegra PCIe
Date: Thu, 11 Jan 2018 11:38:04 +0530 [thread overview]
Message-ID: <1515650888-9459-4-git-send-email-mmaddireddy@nvidia.com> (raw)
In-Reply-To: <1515650888-9459-1-git-send-email-mmaddireddy-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
Primary, secondary and subordinate default bus numbers are 0 in Tegra and
it is expecting SW to program these numbers in configration space.
pci_scan_bridge_extend() function programs these numbers in configuration
space if secondary & subordinate bus numbers are 0 or PCI_REASSIGN_ALL_BUS
flag is set. Since secondary & subordinate default bus numbers are 0,
PCI_REASSIGN_ALL_BUS flag can be removed for Tegra PCIe.
