The Hammerhead platform is built around a AVR32 32-bit microcontroller from Atmel.
It offers versatile peripherals, such as ethernet, usb device, usb host etc.
The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered
Device (PD).
Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
will cover even the most exceptional need of memory bandwidth. Together with the onboard
video decoder the board is ready for video processing.

# Hammerhead customization
if BOARD_HAMMERHEAD
config BOARD_HAMMERHEAD_USB
bool "Philips ISP116x-hcd USB support"
help
This enables USB support for Hammerheads internal ISP116x
controller from Philips.
Choose 'Y' here if you want to have your board USB driven.
config BOARD_HAMMERHEAD_LCD
bool "Atmel AT91/AT32 LCD support"
help
This enables LCD support for the Hammerhead board. You may
also add support for framebuffer devices (AT91/AT32 LCD Controller)
and framebuffer console support to get the most out of your LCD.
Choose 'Y' here if you have ordered a Corona daugther board and
want to have support for your Hantronix HDA-351T-LV LCD.
config BOARD_HAMMERHEAD_SND
bool "Atmel AC97 Sound support"
help
This enables Sound support for the Hammerhead board. You may
also go trough the ALSA settings to get it working.
Choose 'Y' here if you have ordered a Corona daugther board and
want to make your board funky.
config BOARD_HAMMERHEAD_FPGA
bool "Hammerhead FPGA Support"
default y
help
This adds support for the Cyclone III FPGA from Altera
found on Miromico's Hammerhead board.
Choose 'Y' here if you want to have FPGA support enabled.
You will have to choose the "Hammerhead FPGA Device Support" in
Device Drivers->Misc to be able to use FPGA functionality.
