Subject: block2mtd booting impossible?
Date: Fri, 23 Jun 2006 00:14:54 +0900	[thread overview]
Message-ID: <449AB3EE.5000306@radfordnz.net> (raw)

Hi,

(Sorry to bother the devs but I can't find *any* info about this yet)

I have an x86 machine that up until 2.6.16.x was booting from JFFS2 
filesystems via blkmtd (CF card in an IDE adapter). The kernel 
parameters were:
ro root=/dev/mtdblock0 blkmtd_device=/dev/hda2,/dev/hda5,/dev/hda6 
rootfstype=jffs2

That worked well. Is it possible to get the same functionality from 
block2mtd (compiled in, not a module) now that blkmtd has been removed 
in 2.6.17?

My attempt at doing so failed miserably:
ro root=/dev/mtdblock0 block2mtd=/dev/hda2 block2mtd=/dev/hda5 
block2mtd=/dev/hda6 rootfstype=jffs2

I gave multiple block2mtd arguments because I don't see a 
multiple-device capability in the code. Even with just one block2mtd 
argument for the root FS, I just get the no-root panic. Am I missing 
something here? Is JFFS2 block-device translation going to make the 
whole block2mtd, mtdblock arrangement obsolete?

Thanks,
Paul
