mtd: nand: Remove docg4 driver and palmtreo680 flashing tool
Commit ad4f54ea86b ("arm: Remove palmtreo680 board") removed the only user of the docg4 driver and the palmtreo680 image flashing tool. This patch removes them. Signed-off-by: Scott Wood <oss@buserror.net> Cc: Mike Dunn <mikedunn@newsguy.com> Cc: Simon Glass <sjg@chromium.org>
