Valentin Longchamp	8203b201ea	kw_spi: fix clock prescaler computation ... The computation was not correct with low clock values: setting a 1MHz clock would result in an overlap that would then configure a 25Mhz clock. This patch implements a correct computation method according to the kirkwood functionnal spec. table 600 (Serial Memory Interface Configuration Register).

Valentin Longchamp	ac486e3ba1	kw_spi: support spi_claim/release_bus functions ... These two function nows ensure that the MPP is configured correctly for the SPI controller before any SPI access, and restore the initial configuration when the access is over. Since the used pins for the SPI controller can differ (2 possibilities for each signal), the used pins are configured with CONFIG_SYS_KW_SPI_MPP.

Peter Tyser	819833af39	Move architecture-specific includes to arch/$ARCH/include/asm ... This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with.
