Before UBI got into mainline, there was a slight flash format
change - we did not have sequence number support, then added it.
We have carried full support of those ancient images till this
moment. Now the support is removed, well, not fully removed.
Now UBI will support only _clean_ old images, which were cleanly
detached last time (just before kernel upgrade). This is most
likely the case.
But we will not support unclean ancient images. Surprisingly,
this allows us to remove a big chunk of legacy code.
And the same should be true for downgrading: clean images should
downgrade fine, but unclean ones will not.

UBI: fix kernel-doc errors and warnings2008-07-24T10:36:09ZArtem Bityutskiy2008-07-18T10:34:32Zurn:sha1:ebaaf1af3e9ef05c4fb7c61e4530c15e1ad10e3b
No functional changes, just tweak comments to make kernel-doc
work fine and stop complaining.

UBI: fix mean EC calculation2008-04-19T17:49:41ZArtem Bityutskiy2008-04-19T17:44:31Zurn:sha1:4bc1dca4b0eb4dfbf100895bfc1256f21e3c901a
(a + b) / (c + d) != a / c + b / d. The old code errornously
assumed this incorrect formuld. Instead, just sum all erase
counters in a 64-bit variable and divide to the number of EBs
at the end.
Thanks to Adrian Hunter for pointing this out.

UBI: add layout volume information2008-01-25T14:41:25ZArtem Bityutskiy2008-01-24T09:23:23Zurn:sha1:91f2d53cd75a8fa3557246af965155208c4c69a7
Add more information about layout volume to make userspace tools
use the macros instead of constants. Also rename UBI_LAYOUT_VOL_ID
to make it consistent with other macros.
