dfu: add backend for MTD device
Add DFU backend for MTD device: allow to read and write on all MTD device (NAND, SPI-NOR, SPI-NAND,...) For example : > set dfu_alt_info "nand_raw raw 0x0 0x100000" > dfu 0 mtd nand0 This MTD backend provides the same level than dfu nand backend for NAND and dfu sf backend for SPI-NOR; So it can replace booth of them but it also add support of spi-nand. > set dfu_alt_info "nand_raw raw 0x0 0x100000" > dfu 0 mtd spi-nand0 The backend code is based on the "mtd" command introduced by commit 5db66b3aee6f ("cmd: mtd: add 'mtd' command") Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
