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/.

176 Say Y here and pass the nmi_debug command-line parameter to
177 the kernel to turn on NMI debugging. Depending on the value
178 of the nmi_debug option, various pieces of information will
179 be dumped to the console when a Non-Maskable Interrupt

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