Updates for atevk1100 support

These patches makes it possible to load code into external SRAM on the atevk1100.

Also included is a patch to use the internal flash. Before this can be done, U-Boot must be relocated to SRAM.

The GPIO implementation is made cpu dependent due to differences between at32uc and ap700x.

Gunnar Rangoy (6):
AVR32: Make GPIO implmentation cpu dependent
AVR32: Support for external SRAM on at32uc3
AVR32: Use SRAM as main memory on the atevk1100 board
AVR32: Enable relocation of code for at32uc3
AVR32: Support for writing to internal flash on at32uc3
AVR32: Set boot parameters for atevk1100
