Er, so if you're cross-building your file system on an IA64, it gets a page
size of 16KiB by default? No likee :)
Anyway, page size isn't even always 16KiB on IA64 either, is it? Stick to
4KiB default -- it's safer. If you know the target system has a larger page
size, you can specify it on the command line. Same logic as keeping the
erase size small by default.
How about changing cpu_to_target32() et al. to be cpu_to_je32() to match the
JFFS2 code?
Also, could we have an option to write cleanmarkers to the beginning of
each block?
