++----------------------------
++
++What: pci_scan_bus_parented()
++When: 3.5
++Why: The pci_scan_bus_parented() interface creates a new root bus. The
++ bus is created with default resources (ioport_resource and
++ iomem_resource) that are always wrong, so we rely on arch code to
++ correct them later. Callers of pci_scan_bus_parented() should
++ convert to using pci_scan_root_bus() so they can supply a list of
++ bus resources when the bus is created.
++Who: Bjorn Helgaas <bhelgaas@google.com>

-Subject: [PATCH 23/31] bcma: add the core unit number
-
-Some SoCs have two pcie or gmac cores and we need to know the number of
-the specific core on the bus. This is the case for the BCM4706.

-Subject: [PATCH 26/32] bcma: make some functions __devinit
-
-bcma_core_pci_hostmode_init() has to be in __devinit as it will call a
-function in that section and so all functions calling it also have to
-be in __devinit.

-Subject: [PATCH 25/34] bcma: add PCIe host controller
-
-Some SoCs have a PCIe host controller to make it possible to attach
-some other devices to it, like an other Wifi card.
-This code was tested with an Netgear WNDR3400 (bcm4716 based), but
-should work with all bcma based SoCs.

+Subject: [PATCH 25/34] bcma: add PCIe host controller
+
+Some SoCs have a PCIe host controller to make it possible to attach
+some other devices to it, like an other Wifi card.
+This code was tested with an Netgear WNDR3400 (bcm4716 based), but
+should work with all bcma based SoCs.
