initrd support in uclinux

I am using U-boot for booting uclinux-2.6.x kernel on nios2 architecture.

In doing so I was NOT able to find initrd support in uclinux. I enabled the initrd support in make menuconfig, but the build failed, and disabling initrd support the build passed.

I tried looking for other boot parameters (board info, initrd_start , initrd_stop, cmd line parameters start and end ) passing from U-boot to kernel but not able to find them used in uclinux code.

For example in previous projects, the boot loader will pass /dev/nfs with nfs serverip etc,. in command line string to have nfs mounted as root filesystem, and /dev/ram for initrd support without changing the kernel support.

So my question is does uClinux takes kernel parameters like board info, initrd_start, end, command line start and end, which a normal Linux kernel will take
