/*
* ======== EK_TM4C1294XL.c ========
* This file is responsible for setting up the board specific items for the
* EK_TM4C1294XL board.
*
* The following defines are used to determine which TI-RTOS peripheral drivers
* to include:
* TI_DRIVERS_EMAC_INCLUDED
* TI_DRIVERS_GPIO_INCLUDED
* TI_DRIVERS_I2C_INCLUDED
* TI_DRIVERS_SDSPI_INCLUDED
* TI_DRIVERS_SPI_INCLUDED
* TI_DRIVERS_UART_INCLUDED
* TI_DRIVERS_USBMSCHFATFS_INCLUDED
* TI_DRIVERS_WATCHDOG_INCLUDED
* TI_DRIVERS_WIFI_INCLUDED
* These defines are created when a useModule is done on the driver in the
* application's .cfg file. The actual #define is in the application
* generated header file that is brought in via the xdc/cfg/global.h.
* For example the following in the .cfg file
* var GPIO = xdc.useModule('ti.drivers.GPIO');
* Generates the following
* #define TI_DRIVERS_GPIO_INCLUDED 1
* If there is no useModule of ti.drivers.GPIO, the constant is set to 0.
*
* Note: a useModule is generated in the .cfg file via the graphical
* configuration tool when the "Add xxx to my configuration" is checked
* or "Use xxx" is selected.
