Commit bf4289cba0 ("ATMEL: fix nand ecc support") indicated that it
wanted to "Move platform data to a common header
include/linux/platform_data/atmel_nand.h" and the new header even had
re-include protectors with:
#ifndef __ATMEL_NAND_H__
However, the file that was added was simply called atmel.h
and this caused avr32 defconfig to fail with:
In file included from arch/avr32/boards/atstk1000/setup.c:22:
arch/avr32/mach-at32ap/include/mach/board.h:10:44: error: linux/platform_data/atmel_nand.h: No such file or directory

Allow the use of another DMA controller driver in atmel-mci sd/mmc driver.
This adds a generic dma_slave pointer to the mci platform structure where
we can store DMA controller information. In atmel-mci we use information
provided by this structure to initialize the driver (with new helper
functions that are architecture dependant).
This also adds at32/avr32 chip modifications to cope with this new access
method.

at32ap_spi_setup_slaves() is exposed to allow the addition of SPI slaves
to a SPI bus that has already been registered. This is especially
useful for add-on cards, which have their own board setup function.
at32ap_spi_add_device() has been slightly re-organized, but should be
transparent to existing users.
So to add a SPI slave, after a SPI bus has already been registered:
/* Configure the list of slaves on SPI controller "id" */
at32_spi_setup_slaves(id,spi_board_info,ARRAY_SIZE(spi_board_info));
/* Register the list of slaves */
spi_register_board_info(spi_board_info,ARRAY_SIZE(spi_board_info));
