* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and the
* matching application logic. The value could be such things as a

* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.

* Name: xmc4_spi[n]select, xmc4_spi[n]status, and xmc4_spi[n]cmddata

* SPI interface defined by struct spi_ops_s (see include/nuttx/spi/spi.h).
* All other methods including xmc4_spibus_initialize()) are provided by

*
* 1. Provide logic in xmc4_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide xmc4_spi[n]select() and xmc4_spi[n]status() functions
* in your board-specific logic. These functions will perform chip
* selection and status operations using GPIOs in the way your board
* is configured.
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
* xmc4_spi[n]cmddata() functions in your board-specific logic. These
* functions will perform cmd/data selection operations using GPIOs in
* the way your board is configured.
* 3. Add a call to xmc4_spibus_initialize() in your low level application
* initialization logic
* 4. The handle returned by xmc4_spibus_initialize() may then be used to
* bind the SPI driver to higher level logic (e.g., calling
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
* the SPI MMC/SD driver).

/****************************************************************************
* Name: xmc4_spi[n]select

* Description:
* PIO chip select pins may be programmed by the board specific logic in

* peripherals. In that case, the pins are completely controlled by the
* SPI driver. This method still needs to be provided, but it may be only
* a stub.
*
* An alternative way to program the PIO chip select pins is as a normal
* GPIO output. In that case, the automatic control of the CS pins is
* bypassed and this function must provide control of the chip select.
* NOTE: In this case, the GPIO output pin does *not* have to be the
* same as the NPCS pin normal associated with the chip select number.

* devid - Identifies the (logical) device
* selected - TRUE:Select the device, FALSE:De-select the device
