Hi,
I can boot my (powerpc 440gx) board as a "triple" uImage (kernel + external_initramfs + fdt) using tftp.
(external_initramfs here means an initramfs gzip'd cpio file archive that is not linked into the kernel as one file.)
I can also load the individual components and boot via bootm.
What I can't get to work is a "double" uImage (kernel + external_initramfs) and external fdt. "bootm uImage_addr - fdt_addr" panics when it attempts to mount the initramfs filesystem. I assume that is because bootm isn't passing the address of the initramfs to the kernel.
So, is there a way to do this? Is there a way to tftp the uImage and then obtain pointers to the two file components so that bootm could be supplied the address of the initramfs blob?
Thanks,
Marc Howard
