Hi Arnout,

I use the buildroot system to build the uImage and rootfs.cpio file, I am
not building image linked with rootfs file system.

CONFIG_BLK_DEV_INITRD=y
CONFIG_INITRAMFS_SOURCE=""

I want to pass boot arguments to kernel to use my file system(rootfs.cpio)

Ex: uImage located on DRAM address = 0x60080000
       rootfs.cpio  DRMA        address   = 0x61000000

my boot arguments
===============
root=/dev/mem rw initrd=0x61000000,8M init=/init console=ttyS1
ip=192.168.1.12:::::eth0:off



init file 
==========

/bin/mount -t devtmpfs devtmpfs /dev

exec 0</dev/console
exec 1>/dev/console
exec 2>/dev/console

exec /sbin/init $*


Thanks & regards,
Raj
