Subject: [PATCH 09/63] MIPS: BCM63XX: remove SPI2 register
This register was introduced with the support of the BCM6368 CPU in the idea
that its internal layout was different from the other CPUs SPI controller.
The controller is actually the same as the one present on BCM6358 so we can
remove this register and use the usual SPI register instead.

Subject: [PATCH 10/63] MIPS: BCM63XX: define internal registers offsets of the SPI controller
BCM6338, BCM6348, BCM6358 and BCM6368 basically use the same SPI controller
though the internal registers are shuffled, which still allows a common
driver to drive that IP block.

Subject: [PATCH 11/63] MIPS: BCM63XX: add stub to register the SPI platform driver
This patch adds the necessary stub to register the SPI platform driver.
Since the registers are shuffled between the 4 BCM63xx CPUs supported by
this SPI driver we also need to generate the internal register layout and
export this layout for the driver to use it properly.

Subject: [PATCH] mtd: bcm63xxpart: handle Broadcom partition order
The original Broadcom partition order has the root fs in front of the
kernel, which resulted in miscalculated partition sizes.
Detect when such an image is on the flash and also reorder the partitions
accordingly.

Subject: [PATCH] spi/bcm63xx: convert to the pump message infrastructure
This patch converts the bcm63xx SPI driver to use the SPI infrastructure
pump message queue. Since we were previously sleeping in the SPI
driver's transfer() function (which is not allowed) this is now fixed as well.
To complete that conversion a certain number of changes have been made:
- the transfer len is split into multiple hardware transfers in case its
size is bigger than the hardware FIFO size
- the FIFO refill is no longer done in the interrupt context, which was a
bad idea leading to quick interrupt handler re-entrancy

Subject: [PATCH] spi/bcm63xx: don't use the stopping state
We do not need to use a flag to indicate if the master driver is stopping
it is sufficient to perform spi master unregistering in the platform
driver's remove function.

Subject: [PATCH 2/8] MIPS: BCM63XX: Add flash type detection
On BCM6358 and BCM6368 the attached flash type is exposed through a
bootstrapping register. Use it for auto detecting the flash type on
those and default to parallel flash for earlier SoCs.

Subject: [PATCH 3/8] MIPS: BCM63XX: Use the Chip ID register for identifying the SoC
Newer BCM63XX SoCs use virtually the same CPU ID, differing only in the
revision bits. But since they all have the Chip ID register at the same
location, we can use that to identify the SoC we are running on.

Subject: [PATCH 4/8] MIPS: BCM63XX: Add basic BCM6328 support
This includes CPU speed, memory size detection and working UART, but
lacking the appropriate drivers, no support for attached flash.

[PATCH] MIPS: BCM63XX: fix BCM6345 clock bits shifting
BCM6345 has an intermediate 16-bits wide test control register between the
peripheral identifier function, and its clock control register is only 16-bits
wide contrary to other platforms where it is 32-bits wide. By shifting all
clocks bits by 16-bits to the left we ensure they get written to the proper
clock control register, without adding specific BCM6345 handling in the clock
code.

The CFE does not use 4K sectors even if the flash supports it, so
for the fixed partitions like CFE itself or NVRAM the erase block
size is always 64k or bigger.

Subject: [PATCH 3.7] spi/bcm63xx: fix transfer bits_per_words check
Transfers often do not have bits_per_words set, so use the spi device's
bits_per_words in this case.
This fixes the driver rejecting valid transfers e.g. generated by
spi_write() or spi_read().

Subject: [PATCH] spi/bcm63xx: fix multi transfer messages
The BCM63XX SPI controller does not support keeping CS asserted after
sending its buffer. This breaks common usages like spi_write_then_read,
where it is expected to be kept active during the whole transfers.
Work around this by combining the transfers into one if the buffer
allows. For spi_write_then_read, use the prepend byte feature to write
to "prepend" the write if it is less than 15 bytes, allowing the whole
fifo size for the read.
Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com>
---
Tested on a SPI conntected switch which required keeping CS active between
the register read command and reading the register contents.
Based on Mark's spi/next.
Not sure if this is stable material, as it's quite invasive.

Subject: [PATCH 04/59] Revert "MIPS: BCM63XX: Call board_register_device from device_initcall()"
This commit causes a race between PCI scan and SSB fallback SPROM handler
registration, causing the wifi to not work on slower systems. The only
subsystem touched from board_register_device is platform device
registration, which should be safe as an arch init call.
This reverts commit d64ed7ada2f689d2c62af1892ca55e47d3653e36.

Date: Fri, 6 Jan 2012 12:24:18 +0100
Subject: [PATCH 19/63] NET: bcm63xx_enet: move phy_(dis)connect into probe/remove
Only connect/disconnect the phy during probe and remove, not during any
open/close. The phy seldom changes during the runtime, and disconnecting
the phy during close will prevent it from keeping any configuration over
a down/up cycle.

Subject: [PATCH] bcm63xx_enet: reset port link state in bcm_enetsw_open
bcm_enetsw_open disables all ports, but does not reset their link state.
This results in connected ports staying disabled after a ifdown/ifup
cycle, since bcm_enetsw_phy_poll only enables them if their current state
is different from the stored link state.
Fix this by also resetting the port link state.
