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

187 the kernel to turn on NMI debugging. Depending on the value
188 of the nmi_debug option, various pieces of information will

201 to the kernel, you may specify one here. As a minimum, you should specify
202 the memory size and the root device (e.g., mem=8M, root=/dev/nfs).
