Hello Jason Liu,
Is there a glossary for the defines used in the
/include/configs/<board_name.h> files?
Regards,
Bud Miljkovic

I find it far easier to just grep the code.

The symbols should be documented in README or under doc/ (though some
are probably missing).

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
