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

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

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