HOW To boot the hole raspberry pi tftp or nfs from nas ??

[patrikg]

Compiled u-boot in raspbian to make it possible to tftp nfs the kernel and initramfs ramdisk.

kernel_addr_r=0x01000000
ramdisk_addr_r=0x02100000

It working great with raspbian to install, because it not using initramfs just kernel.img 
Just to set bootargs and fatload mmc 0:1 ${kernel_addr_r} kernel.img
and bootz ${kernel_addr_r}

I see in orginal boot system the config.txt picore loads first kernel.img and after 7.0.gz.
And how do i pass to the kernel the address to the 7.0.gz file ?
Does any body knows how to do this... i have seen Simon on this forum to
do something with this..but nobody has answered.

Maybe it's only mem addr failure in Simon case.
