Can you try to replace initrd=0x80800000,16M with noinitrd?
Also, do you have only 16M on your board?
Are you booting with a JTAG cable connected to your MX35 board? If not, you can remove nohlt option from the kernel command line.
On the MX31ADS you can boot a mainline kernel as follows:

Maybe you can LTIB tool from Freescale to generate your rootfs.
Hope it helps.
