+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.
