[U-Boot] [PATCH v3 0/4] introduce nand write.trimffs

[Ben Gardiner]

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.

[1] http://www.linux-mtd.infradead.org/doc/ubi.html#L_flasher_algo

Changes since v2:
 * dropped WITH_DEFAULTS in favour of '0'
 * moved copyright header to nand_util patch
 * added write.trimffs variant to README.nand

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

  [v3] nand_util: convert nand_write_skip_bad() to flags
