15 AVR32 is a high-performance 32-bit RISC microprocessor core,
16 designed for cost-sensitive embedded applications, with particular
17 emphasis on low power consumption and high code density.
19 There is an AVR32 Linux project with a web page at
20 http://avr32linux.org/.

163 If you don't have a boot loader capable of passing a command line string
164 to the kernel, you may specify one here. As a minimum, you should specify
165 the memory size and the root device (e.g., mem=8M, root=/dev/nfs).
