+ help
+ Many flash memories support erasing small (4096 B) sectors. Depending
+ on the usage this feature may provide performance gain in comparison
+ to erasing whole blocks (32/64 KiB).
+ Changing a small part of the flash's contents is usually faster with
+ small sectors. On the other hand erasing should be faster when using
+ 64 KiB block instead of 16 × 4 KiB sectors.
+
+ Please note that some tools/drivers/filesystems may not work with
+ 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

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:

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.

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

Without this fix kernel was randomly hanging in ~25% of tries during
early init. Hangs used to happen at random places in the start_kernel.

Subject: [PATCH V2] ARM: BCM5301X: select GPIOLIB as optional
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
All routers (or 99% of them) based on BCM5301X use GPIOs to control LEDs
and buttons.
Signed-off-by: Rafał Miłecki <zajec5@gmail.com>

V2: Don't select GPIOLIB. We may still think about making it default at
some point, but we dont' really require it to boot successfully.

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.

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?
