Here is a uboot setup that works with a freescale kernel: bootdelay=5 baudrate=115200 preboot=echo;echo Type "run flash_nfs" to mount root filesystem over NFS;echo autoload=no ethact=FEC ETHERNET ramargs=setenv bootargs root=/dev/ram rw jffs2args=setenv bootargs root=/dev/mtdblock0 rw rootfstype=jffs2 addip=setenv bootargs $(bootargs) ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask):$(hostname):$(netdev):off panic=1 flash_nfs=run nfsargs addip;bootm $(kernel_addr) flash_self=run ramargs addip;bootm $(kernel_addr) $(ramdisk_addr) flash_jffs2=run jffs2args;bootm $(kernel_addr) net_nfs=tftp 200000 $(bootfile);run nfsargs addip;bootm netdev=eth0 ethaddr=00:04:9f:22:33:44 bootfile=/tftpboot/uImage kernel_addr=ffd00000 rootpath=/tftpboot/ltib filesize=c9d700 fileaddr=1000000 gatewayip=172.27.255.254 netmask=255.255.0.0 ipaddr=172.27.152.99 serverip=172.27.152.5 bootcmd=run net_nfs nfsargs=setenv bootargs console=ttyS0,115200 root=/dev/nfs rw nfsroot=$(serverip):$(rootpath) stdin=serial stdout=serial stderr=serial
Change ip info, bootfile, rootpath etc to fit you config. If you want it to work with Sylvain's kernel then you need to change ttyS0 to ttyPSC0. Also add a printenv just before the bootm so you can verify that your bootargs really are getting set correctly.
