In the FWU Multi Bank Update feature, the information about the updatable images is stored as part of the metadata, on a separate region. Add a driver for reading from and writing to the metadata when the updatable images and the metadata are stored on a raw MTD region. The code is divided into core under drivers/fwu-mdata/ and some helper functions clubbed together under lib/fwu_updates/ Signed-off-by: Masami Hiramatsu <masami.hiramatsu@linaro.org> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
