[PATCH 0/2] Support skipping bad blocks when seeking to start address

[Mike Crowe]

I found myself needing to write and verify part of a partition that
will be read by the bootloader by skipping blocks from the start of
the partition. Initially I added separate --input-skip and
--output-skip options but David Oberhollenzer suggested in
<cdfdbe5d-1aa8-e424-7691-338d0d63f7b1 at sigma-star.at>
http://lists.infradead.org/pipermail/linux-mtd/2016-December/070855.html
that a simple flag to indicate that the start address should skip bad
blocks would avoid ambiguity.

David also suggested that I skip the bad blocks in a separate step
before the already-cluttered main loop.

This version uses is_virt_block_bad in nandwrite, so the series now depends
on David Oberhollenzer's virtual block handling fixes from
