-Subject: [PATCH 1/3] ARM: BCM5301X: initial support for the BCM5301X/BCM470X
- SoCs with ARM CPU
-
-This patch adds support for the BCM5301X/BCM470X SoCs with an ARM CPUs.
-Currently just booting to a shell is working and nothing else, no
-Ethernet, wifi, flash, ...
-I have some pending patches to make Ethernet work for this device.
-Mostly device tree support for bcma is missing.
-
-This SoC is used in small office and home router with Broadcom SoCs
-it's internal name is Northstar. This code should support the BCM4707,
-BCM4708, BCM4709, BCM53010, BCM53011 and BCM53012 SoC. It uses one or
-two ARM Cortex A9 Cores, some highlights are 2 PCIe 2.0 controllers,
-4 Gigabit Ethernet MACs and a USB 3.0 host controller.
-
-This SoC uses a dual core CPU, but this is currently not implemented.
-More information about this SoC can be found here:
-http://www.anandtech.com/show/5925/broadcom-announces-bcm4708x-and-bcm5301x-socs-for-80211ac-routers

-Subject: [PATCH 3/3] ARM: BCM5301X: workaround suppress fault
-
-Without this patch I am getting a unhandled fault exception like this
-one after "Freeing unused kernel memory":
-
-Freeing unused kernel memory: 1260K (c02c1000 - c03fc000)
-Unhandled fault: imprecise external abort (0x1c06) at 0xb6f89005
-Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000007
-
-The address which is here 0xb6f89005 changes from boot to boot, with a
-new build the changes are bigger. With kernel 3.10 I have also seen
-this fault at different places in the boot process, but starting with
-3.11 they are always occurring after the "Freeing unused kernel memory"
-message. I never was able to completely boot to userspace without this
-handler. The abort code is constant 0x1c06. This fault just happens
-once in the boot process I have never seen it happing twice or more.
-
-I also tried changing the CPSR.A bit to 0 in init_early, with this code
-like Afzal suggested, but that did not change anything:
-asm volatile("mrs r12, cpsr\n"
- "bic r12, r12, #0x00000100\n"
- "msr cpsr_c, r12" ::: "r12", "cc", "memory");
-
-Disabling the L2 cache by building with CONFIG_CACHE_L2X0 unset did not
-help.
-
-This workaround was copied from the vendor code including most of the
-comments. It says it they think this is caused by the CFE boot loader
-used on this device. I do not have any access to any datasheet or
-errata document to check this.

-Subject: [PATCH] ARM: BCM5301X: Add IRQs to Broadcom's bus-axi in DTS file
-
-IRQ support for Broadcom's bus-axi driver bcma was merged into John
-Linville's wireless tree and will show up in 3.19. This patch makes use
-of this feature in the DTS file for the the BCM5301X SoCs. I left the
-PCIe controller out, because this still needs some discussion.

-Subject: [PATCH 03/17] bcm47xx-sprom: add Broadcom sprom parser driver
-
-This driver needs an nvram driver and fetches the sprom values from the
-nvram and provides it to any other driver. The calibration data for the
-wifi chip the mac address and some more board description data is
-stores in the sprom.
-
-This is based on a copy of arch/mips/bcm47xx/sprom.c and my plan is to
-make the bcm47xx MIPS SoCs also use this driver some time later.

-Probing is done before the PCIe bridge is fully activated and the
-address spaces does not get assigned to the PCIe devices. Without the
-address space the driver can not register to this device. With this
-patch the driver reregistration is done later.

-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 V2] spi: bcm53xx: driver for SPI controller on Broadcom bcma
- SoC
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Broadcom 53xx ARM SoCs use bcma bus that contains various cores (AKA
-devices). If board has a serial flash, it's connected over SPI and the
-bcma bus includes a SPI controller. Example log from such a board:
-bus0: Found chip with id 53010, rev 0x00 and package 0x02
-(...)
-bus0: Core 18 found: SPI flash controller (manuf 0x4BF, id 0x50A, rev 0x01, class 0x0)
-
-This patch adds a bcma driver for SPI core, it registers SPI master
-controller and "bcm53xxspiflash" SPI device.
-
-Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
----
-Since RFC: Add Signed-off-by
- Update to compile on top of for-next
-V2: Use wait timeout
- Describe bcm53xxspi_calc_timeout a bit
- Use devm_spi_register_master
-
-Thanks Mark for your comments!

-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?
