Re: [U-Boot] [PATCH 3/9 v4] i.MX31: support GPIO as a chip-select in the mxc_spi driver

Some SPI devices have special requirements on chip-select handling. With this patch we can use a GPIO as a chip-select and strictly follow the SPI_XFER_BEGIN and SPI_XFER_END flags.

Changes since v1: long lines split, mx31_gpio_* calls now also defined if CONFIG_MX31_GPIO is not defined (see patch 2/9), '!!' removed. Changes since v2: added braces in a multiline if, switched to ARRAY_SIZE(). Changes since v3: moved GPIO chipselect initialisation into a separate function, as suggested by Wolfgang Denk
