dfu: fix dfu tftp on sandbox

2020-09-01T12:47:43+00:00

The environment variable loadaddr is in the virtual address space of the
sandbox. To get the actual memory address where the FIT image has been
loaded we have to convert this address according to the memory mapping of
the sandbox.

Equally the addresses in the *.its file have to be converted when used in
the dfu_ram driver.

dfu: Add optional timeout parameter

2020-01-07T13:37:50+00:00

When the `dfu` command is called from the U-Boot environment,
it now accepts an optional parameter that specifies a timeout (in seconds).
If a DFU connection is not made within that time the `dfu` command exits
(as it would if Ctrl+C was pressed). If the timeout is left empty or being
zero the `dfu` command behaves as it does now.

This is useful for allowing U-Boot to check to see if anything wants to
upload new firmware before continuing to boot.

The patch is based on the commit
https://github.com/01org/edison-u-boot/commit/5e966ccc3c65c18c9783741fa04e0c45e021780c
by Sebastien Colleur, which has been heavily reworked due to U-Boot changes
in the past.

After the commit 1cc03c5c53c0 ("dfu: Provide means to find difference between
dfu-util -e and -R") the dangling ptototype appeared. Remove it here.

dfu: add partition support for MTD backend

2019-10-31T11:12:31+00:00

Add the support of MTD partition for the MTD backend.

The expected dfu_alt_info for one alternate on the mtd device :
	 part 
         partubi 

"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"

dfu: add backend for MTD device

2019-10-31T11:12:31+00:00

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")
