+ * This board file is used for the following setup:
+ * An ILI9488 display controller connected to an STM32F446VET micro controller through a 16-bit
+ * parallel interface (Intel 8080 compatible). The FMC interface of the STM32 micro controller is used.
+ * LCD_CS is hooked up to NE1 (first SRAM bank) and LCD_RS is hooked up to A16.
