+Subject: [PATCH 1/2] PCI: BCM5301X: add PCIe2 driver for BCM5301X SoCs
+
+This driver supports the PCIe controller found on the BCM4708 and
+similar SoCs. The controller itself is automatically detected by bcma.
+
+This controller is found on SoCs usually used in SOHO routers to
+connect the wifi cards to the SoC. All the of the BCM5301X SoCs I know
+of have 2 or 3 of these controllers in the SoC.
+
+I had to use PCI domains otherwise the pci_create_root_bus() function
+in drivers/pci/probe.c would fail for the second controller being
+registered because pci_find_bus() would find the same PCIe bus again
+and assume it is already registered, which ends up in a kernel panic in
+pcibios_init_hw() in arch/arm/kernel/bios32.c
+
+The ARM PCI code assumes that every controller has an I/O space and
+adds a dummy area if the driver does not specify one. This will work
+for the first controller, but when we register the second one this will
+result in an error. To prevent this problem we add an empty I/O space.
+
+Currently I have problems with probing the devices on the bus, because
+pci_bus_add_devices() is called too early in pci_scan_root_bus() in
+drivers/pci/probe.c, before pci_bus_assign_resources() was called in
+pci_common_init_dev() in arch/arm/kernel/bios32.c. When the devices are
+added too early they do not have any resources and adding fails. I have
+to remove the call to pci_bus_add_devices() in pci_scan_root_bus() to
+make registration work, calling pci_bus_add_devices() later again does
+not fix this problem.

+Subject: [PATCH] USB: bcma: remove chip id check
+
+I have never seen any bcma device with an USB host core which was not a
+SoC, the bcma devices have an USB device core with a different core id.
+Some SoC have IDs with 47XX and 53XX in decimal form which would be
+rejected by this check. Instead of fixing this check just remove it.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In OpenWrt we still use old NAND driver instead of "brcm,nandcs", so
+we need to add this DT entry back.

++ * Also, when the page is erased, but OOB data is not, HW ECC will

+Subject: [PATCH] bgmac: add support for the 3rd bus core (device)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+So far we were supporting up to 2 cores but recent devices (e.g. Netgear
+R8000) may use 3rd as well. Lower ones (1st, 2nd) are usually used for
+some offloading then.

+Subject: [PATCH RFC] bcma: use two different initcalls if built-in
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This is needed as we can't initialize bus during fs_initcall.
+Initialization requires SPROM which depends on NVRAM which depends on
+mtd. Since mtd, spi, nand, spi-nor use standard module_init, we have to
+do the same in bcma.
+Without this we'll try to initialize SPROM without having a ready SPROM
+proviver registered using bcma_arch_register_fallback_sprom.
+
+Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
+---
+While this patch seems to work and I can compile bcma as built-in and
+module, I'm not too proud of it. I don't really like these #if(n)def
+tricks and I'm afraid bcma_modinit may be called even if
+bcma_modinit_early failed.
+
+Do you see any better idea of solving this?
