console
The console settings. When using this
option, you will need to specify the serial console port and baud rate.
For example: console=ttyS0,38400 where ttyS0 is the serial console port
and 38400 is the baud rate for the serial port. Another example:
console=ttyS0,384008N1 where 8 is is data bits, N is odd parity and 1
is stop bits.
maxcpus=
Allows to limit the number of processors to be used on a multiprocessor systems.
nfsroot
If
the root filesystem for a board is mounted from a remote NFS server,
this option can be used to specify the NFS server and the NFS
filesystem. This option can be used as: nfsroot=:.
For example: nfsroot=10.0.0.139:/opt/mips_le_fs, where 10.0.0.139 is
the NFS server name and /opt/mips_le_fs is the remote filesystem
exported by the NFS server.
nofpu
Can be used to disable the
FPU entirely. In this the kernel FPU emulation will take over floating
point processing. Useful if a FPU is known to be defective, has
accuracy problems and wrongly detected as present even though none
exists.
nosmp
Disable SMP. Same as maxcpus=0.
nowait
Disable the use of the wait instruction for powersaving.
rd_start
The base address of a loaded ramdisk image. This option was added in Linux 2.6.10-rc2. See also rd_size.
rd_size
The size of a loaded ramdisk image. This option was added in Linux 2.6.10-rc2. See also rd_start.
root
This
option is used to specify the root filesystem. For example, if the root
filesytem resides on the second partition of a SCSI device /dev/sda,
then this can be specified as: root=/dev/sda2. Similarly, when the root
filesystem is mounted over NFS, root=/dev/nfs can be used.
