OMG, again same question,

Andrea, check ml archive, I already sent patch half-year ago
(http://ozlabs.org/pipermail/linuxppc-embedded/2006-April/022566.html)
Problem is in alignment/memcpy: JFFS2 code assumed that memory at
unaligned addresses could be touched, but access to an external MMIO
on MPC5200 _must_ be aligned (i.e. you could not read u32 from odd address).

P.S. Artem, I repeat, I sent this patch _HALF_YEAR_AGO_
how about to fix scan.c?
