Tom Rini 10f7c0a965 UPSTREAM: Revert "spi: atmel: Drop non-dm code"
As we aren't quite able to convert some platforms with a very small size
limit in SPL yet, we need to revert this for now.

This reverts commit 7b0947787358c6b277431d6b76ce043d8bec641d.

Jagan Teki c7aa08536c UPSTREAM:spi: atmel: Drop non-dm code
All board configs are now enabled DM_SPI for SPL and
U-Boot proper, so now its time to drop non-dm code.

Heiko Schocher f11dea4f3d spi, atmel: move CONFIG_SYS_SPI_WRITE_TOUT into common header
move CONFIG_SYS_SPI_WRITE_TOUT into drivers/spi/atmel_spi.h
and define a default value. Delete this define in the board
config files, where it is possible (all boards use currently
the same value).

Hans-Christian Egtvedt 60445cb5c3 atmel_spi: Driver for the Atmel SPI controller
This adds a driver for the SPI controller found on most AT91 and AVR32
chips, implementing the new SPI API.

Changed in v4:
  - Update to new API
  - Handle zero-length transfers appropriately. The user may send a
    zero-length SPI transfer with SPI_XFER_END set in order to
    deactivate the chip select after a series of transfers with chip
    select active. This is useful e.g. when polling the status
    register of DataFlash.
