2019-10-31dfu: add backend for MTD devicePatrick Delaunay1-0/+10
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>
2019-10-31dfu: allow to manage DFU on several devicesPatrick Delaunay1-3/+55
Add support of DFU for several interface/device with one command. The format for "dfu_alt_info" in this case is : - <interface> <dev>'='alternate list (';' separated) - each interface is separated by '&' The previous behavior is always supported. One example for NOR (bootloaders) + NAND (rootfs in UBI): U-Boot> env set dfu_alt_info \ "sf 0:0:10000000:0=spl part 0 1;u-boot part 0 2; \ u-boot-env part 0 3&nand 0=UBI partubi 0,3" U-Boot> dfu 0 list DFU alt settings list: dev: SF alt: 0 name: spl layout: RAW_ADDR dev: SF alt: 1 name: ssbl layout: RAW_ADDR dev: SF alt: 2 name: u-boot-env layout: RAW_ADDR dev: NAND alt: 3 name: UBI layout: RAW_ADDR U-Boot> dfu 0 $> dfu-util -l Found DFU: [0483:5720] ver=9999, devnum=96, cfg=1,\ intf=0, alt=3, name="UBI", serial="002700333338511934383330" Found DFU: [0483:5720] ver=9999, devnum=96, cfg=1,\ intf=0, alt=2, name="u-boot-env", serial="002700333338511934383330" Found DFU: [0483:5720] ver=9999, devnum=96, cfg=1,\ intf=0, alt=1, name="u-boot", serial="002700333338511934383330" Found DFU: [0483:5720] ver=9999, devnum=96, cfg=1,\ intf=0, alt=0, name="spl", serial="002700333338511934383330" Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2019-10-31dfu: sf: add partition support for nor backendPatrick Delaunay1-0/+5
Copy the partition support from NAND backend to SF, support part and partubi option. In case of ubi partition, erase the rest of the partition as it is mandatory for UBI. The added code is under compilation flag CONFIG_DFU_SF_PART activated by default. for example: U-Boot> env set dfu_alt_info "spl part 0 1;\ u-boot part 0 2;u-boot-env part 0 3;UBI partubi 0 4" U-Boot> dfu 0 sf 0:0:10000000:0 Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
