Well..
The direction part is setup somewhere else..
but the other defines is done like this

Code: 
#define LCD_RS   (GPIO_PORTA_DATA_R << 7)

which give me these kind of problems
16: error: lvalue required as left operand of assignment
[cc] LCD_EN = 1;

Yout LCD_DATA if defined like this
Code: 
INT32U LCD_DATA =  GPIO_PORTB_DATA_R;
But it is also troublesome because it gives this error message,
error: initializer element is not constant
[cc] INT32U LCD_DATA = GPIO_PORTB_DATA_R;

#define LCD_RS, LCD_RW, LCD_EN
are bits and you should check your compiler manual about how to define Port bits?

#define LCD_PORT ...
is a complete PORT.
