but fails in linking.

      spi: Add Analog Devices AXI SPI Engine controller support · b1353d1c
      由 Lars-Peter Clausen 提交于 
      This patch adds support for the AXI SPI Engine controller which is a FPGA
soft-peripheral which is used in some of Analog Devices' reference designs.

The AXI SPI Engine controller is part of the SPI Engine framework[1] and
allows memory mapped access to the SPI Engine control bus. This allows it
to be used as a general purpose software driven SPI controller. The SPI
Engine in addition offers some optional advanced acceleration and
offloading capabilities, which are not part of this patch though and will
be introduced separately.

At the core of the SPI Engine framework is a small sort of co-processor
that accepts a command stream and turns the commands into low-level SPI
transactions. Communication is done through three memory mapped FIFOs in
the register map of the AXI SPI Engine peripheral. One FIFO for the command
stream and one each for transmit and receive data.

The driver translates a spi_message in a command stream and writes it to
the peripheral which executes it asynchronously. This allows it to perform
very precise timings which are required for some SPI slave devices to
achieve maximum performance (e.g. analog-to-digital and digital-to-analog
converters). The execution flow is synchronized to the host system by a
special synchronize instruction which generates a interrupt.

      spi/bcm63xx: move register definitions into the driver · 44d8fb30
      由 Jonas Gorski 提交于 
      Move all register definitions and structs into the driver. This allows
us dropping the platform_data struct and drop any arch specific
includes. Make use of different device names to identify the version of
the block we have.

Since we now have full control over the message width, we can drop the
size check, which was broken anyway, since it never set ret to any error
code.

Also since we now have no arch depedendent resources, we can now allow
compiling it for any arch, hidden behind COMPILE_TEST.
