avr32: add support for EarthLCD Favr-32 board
This patch adds support for the Favr-32 board made by EarthLCD.
This kit, which is also called ezLCD-101, has a 10.4" touch screen LCD panel,
16 MB 32-bit SDRAM, 8 MB parallel flash, Ethernet, audio out, USB device,
SD-card slot, USART and various other connectors for cennecting stuff to SPI,
