This series adds a nand write variant which implements the procedure
reccomended in the UBI FAQ [1] of dropping trailing pages of eraseblocks
containing entirely 0xff's.

Changes since v1:
* renamed to 'trimffs' from 'ubi'
* wrapped the new feature in #ifdefs
* don't make it default for jffs -- patch dropped
* attribution of the drop_ffs() function from mtd-utils to Artem
Ben Gardiner (4):
[v2] nand_base: trivial: fix comment read/write comment
[v2] nand_util: convert nand_write_skip_bad() to flags
[v2] nand_util: drop trailing all-0xff pages if requested
[v2] cmd_nand: add nand write.trimffs command
