+Device Firmware Upgrade (DFU)
+
+Overview:
+
+ The Device Firmware Upgrade (DFU) allows to download and upload firmware
+ to/from U-Boot connected over USB.
+
+ U-boot follows the Universal Serial Bus Device Class Specification for
+ Device Firmware Upgrade Version 1.1 the USB forum (DFU v1.1 in www.usb.org).
+
+ U-Boot implements this DFU capability (CONFIG_DFU) with the command dfu
+ (cmd/dfu.c / CONFIG_CMD_DFU) based on:
+ - the DFU stack (common/dfu.c and common/spl/spl_dfu.c), based on the
+ USB DFU download gadget (drivers/usb/gadget/f_dfu.c)
+ - The access to mediums is done in DFU backends (driver/dfu)
+
+ Today the supported DFU backends are:
+ - MMC (RAW or FAT / EXT2 / EXT3 / EXT4 file system)
+ - NAND
+ - RAM
+ - SF (serial flash)
+
+ These DFU backends are also used by
+ - the dfutftp (see README.dfutftp)
+ - the thordown command (cmd/thordown.c and gadget/f_thor.c)
+
+Configuration Options:
+ CONFIG_DFU
+ CONFIG_DFU_OVER_USB
+ CONFIG_DFU_MMC
+ CONFIG_DFU_NAND
+ CONFIG_DFU_RAM
+ CONFIG_DFU_SF
+ CONFIG_CMD_DFU
+
+Environment variables:
+ the dfu command use 3 environments variables:
+ "dfu_alt_info" : the DFU setting for the USB download gadget with a comma
+ separated string of information on each alternate:
+ dfu_alt_info="<alt1>;<alt2>;....;<altN>"
+
+ "dfu_bufsiz" : size of the DFU buffer, when absent, use
+ CONFIG_SYS_DFU_DATA_BUF_SIZE (8MiB by default)
+
+ "dfu_hash_algo" : name of the hash algorithm to use
+
+Commands:
+ dfu <USB_controller> <interface> <dev> list
+ list the alternate device defined in "dfu_alt_info"
+
+ dfu <USB_controller> <interface> <dev>
+ start the dfu stack on the USB instance with the selected medium
+ backend and use the "dfu_alt_info" variable to configure the
+ alternate setting and link each one with the medium
+ The dfu command continue until receive a ^C in console or
+ a DFU detach transaction from HOST.
+
+ The possible values of <interface> are :
+ (with <USB controller> = 0 in the dfu command example)
+
+ "mmc" (for eMMC and SD card)
+ cmd: dfu 0 mmc <dev>
+ each element in "dfu_alt_info" =
+ <name> raw <offset> <size> raw access to mmc device
+ <name> part <dev> <part_id> raw acces to partition
+ <name> fat <dev> <part_id> file in FAT partition
+ <name> ext4 <dev> <part_id> file in EXT4 partition
+
+ with <partid> is the GPT or DOS partition index
+
+ "nand" (raw slc nand device)
+ cmd: dfu 0 nand <dev>
+ each element in "dfu_alt_info" =
+ <name> raw <offset> <size> raw access to mmc device
+ <name> part <dev> <part_id> raw acces to partition
+ <name> partubi <dev> <part_id> raw acces to ubi partition
+
+ with <partid> is the MTD partition index
+
+ "ram"
+ cmd: dfu 0 ram <dev>
+ (<dev> is not used for RAM target)
+ each element in "dfu_alt_info" =
+ <name> ram <offset> <size> raw access to ram
+
+ "sf" (serial flash : NOR)
+ cmd: dfu 0 sf <dev>
+ each element in "dfu_alt_info" =
+ <name> ram <offset> <size> raw access to sf device
+
+Host tools:
+ When U-Boot runs the dfu stack, the DFU host tools can be used
+ to send/receive firmwares on each configurated alternate.
+
+ For example dfu-util is a host side implementation of the DFU 1.1
+ specifications(http://dfu-util.sourceforge.net/) which works with U-Boot.
+
+Usage:
+ Example for firmware located in eMMC or SD card, with:
+ - alternate 1 (alt=1) for SPL partition (GPT partition 1)
+ - alternate 2 (alt=2) for U-Boot partition (GPT partition 2)
+
+ The U-Boot configuration is:
+
+ U-Boot> env set dfu_alt_info "spl part 0 1;u-boot part 0 2"
+
+ U-Boot> dfu 0 mmc 0 list
+ DFU alt settings list:
+ dev: eMMC alt: 0 name: spl layout: RAW_ADDR
+ dev: eMMC alt: 1 name: u-boot layout: RAW_ADDR
+
+ Boot> dfu 0 mmc 0
+
+ On the Host side:
+
+ list the available alternate setting:
+
+ $> dfu-util -l
+ dfu-util 0.9

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.
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

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

This patch allows the DFU backend to indicate that that it can't
provide no more data to fill the DFU buffer, by setting b_left =0
without error, even if the size of received data is lower of the
expected total size indicated by get_medium_size.
For USB DFU stack point of view, it is acceptable:
the read length < requested size in DFU_UPLOAD and the
transaction is stopped.
That avoid infinite loop issue in dfu_read_buffer_fill because the
size for the DFU read is limited by get_medium_size = r_left
and the DFU stack expects that read is allowed up to this size.
This issue never occurs for current flash device (where chunk are
always completely read, and b_left will be never 0) but it is useful for
virtual partition when the backend only know the max size of this
alternate, the real size of the data are only known in the read
treatment.
PS: for file access on mmc, EOF is never reached as
dfu_get_medium_size_mmc returns the exact size of the file.

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")

Add the support of MTD partition for the MTD backend.
The expected dfu_alt_info for one alternate on the mtd device :
<name> part <part_id>
<name> partubi <part_id>
"partubi" also erase up to the end of the partition after write operation.
For example: dfu_alt_info = "spl part 1;u-boot part 2; UBI partubi 3"
U-Boot> dfu 0 mtd nand0

Generate automatically dfu_alt_info for the supported device.
The simple command "dfu 0" allows to start the dfu stack on usb 0
for the supported devices:
- dfu mtd for nand0
- dfu mtd for nor0
- dfu mmc for SDCard
- dfu mmc for eMMC
- dfu ram for images in DDR
The DUF alternate use the "part", "partubi" and "mmcpart" options
to select the correct MTD or GPT partition or the eMMC hw boot partition.

Select the correct USB product id used by the download gadget
for ST stm32mp1 boards.
The board stm32mp1 select the correct product id, as defined in
http://www.linux-usb.org/usb.ids for the STMicroelectronics
vendor id = 0x0483 (CONFIG_USB_GADGET_VENDOR_NUM):
- dfu = 0xdf11 : STM Device in DFU mode
it is the value used by ROM code and reused for stm32prog
command
- fasboot = 0x0afb : Android Fastboot device
- others = 0x5720 (CONFIG_USB_GADGET_PRODUCT_NUM)
Mass Storage Device
it is used for UMS command / usb_dnl_ums
This patch avoid conflict when the same USB VID/PID is used for
ums, fastboot or dfu command (two different protocols associated
to the same PID).
